INTRODUCTION

LIES is a Library Information and Enquiry System thatprovides a user friendly interface and fast access to both thecatalogue and borrower information stored in the system.

This manual is intended to be read in conjunction wi th the L.I.E.SSystem Design document.

RUNNING THE SYSTEM

To start the L.I.E.S system type the commandLIES

at the UNIX system prompt. This command invokes the menu driver programof the system ( L01.x). All menus are contained in this module. ALLmenu seLections invoke the related programs via UNIX system caLLs.The seperation of the individual functions into seperate programsinvoked by UNIX system caLls as opposed to running the whole systemas one (1) program means we are able to dupLicate variabLe andprocedure names within the system thus making programing easier.

OVERVIEW

The L.I.E.S system is designed for the following users:* One Library Manager* One Librarian* Any number of borrowers

The Library Manager and Librarian can both perform functions whichupdate files. Since no file locking is provided these functions must besingle user to avoid corruption of files or a possible system crash. Forthe same reason the Library Manager and Librarian cannot both be usingthe system at the same time. Since borrowers only read access theCatalogue file any number of them can run at the same time, along wi ththe Librarian or the Library manager.

This system allows the users of the system to interactively

2. FILE SYSTEMS

2.1 DESIGN

The L.I.E.S system utilises thirteen (13) files. The filesare divided into four (4) categories; data files, transactionfiles,index files and memory resident data file.

The data files for the system ar~

Ca tal ogue F i l e.Bo r rowe r F i l e .On-Loan F i l e.

Item numberBor r~wEn N"iJ'mberItem_number + Copy_number

Each data file contains fixed length data records inorder of the unique pr imary key. Access to the filesboth sequential and direct. The primary key for eachf 0 l lows:

CatalogueBorrowerOn-Loan Fi leo

The index files for the system are

Author Index File.Ti tle Index File.Subject Index File.Borrower Name Index File.

ascendingcan bedata file is as

and provide an inverted file design approach to indexing. Theindex files are sorted on a non-unique key. Each index recordwill contain a record posi lion of the corresponding datarecord in the data files. The data file can then be accesseddirectly. -The primary key for each index file is as follows:

Author Index Data_author.surnameTi tle Index Ti tle_nameSubject Index Subject_identityBorrower Name Data_borrower.surname

The transaction files for the system are

Catalogue Transact ion File.Borrower Transaction File.Daily (On-Loan) Transaction File.Subject Transaction Fi leo

and will contain all the transactions for the respective data file th~1have been accrued since the last update of the data file. The recordsWill be in date/time order.

The memory resident data file is the

Subject Reference File.

This file is a relative file which initially resides on disk.Had our system been treated as one large program this fileat system startup would have been read into main memory andtreated as an array. By implementing the system as many independantprogram. this is no longer possible and so each time a programwhich requires to use this array (L04.c, L0201.c, L0203.c) is invokedit must call L0101.c to read the file into memory. The subject tablehas been defined as an N-way tree structure, but implemented as astatic array for the following reasons:

- subjects are pre-defnied and, as such, the relationshipsbetween subjects are pre-defined.- the subject heirachy does not change often, and as such adynamio data structure was considered unneoessary.- a subject search is usually linear. In the worst caseaocessing an array linearly is quicker than accessing adynamic data structure.

All file structure defintions ( App 11.1 ) are in separate files.This allows for easy maintenance since a change to any filestructure need only be done in one place and the appropriatemodules recompiled.

2.2 UPDATES

The L.I.E.S system processes mos.t updates in BATCH mode. Themajor file update sequences are

Catalogue Updates.Borrower Updates.On Loan Updates.

These updates cannot be run whi le the system is in use and so must bedone overnight.

These updates are each SHELL procedures which invoke a series of Cprograms and UNIX system commands to perform the update sequence.

The Catalogue Update sequence (L020401.sh) is a sequence of eight(8)procedures that wi II update the Catalogue Data Fi le from the transact ionfiles and recreate all the index files. The sequence steps are

1. Copy all files to a backup copy for safe keeping.2. Sort the Catalogue Transaction file by item_number and

date/time of transaction. Select only the latest transactionfor each item_number and rewri te the transaction file.

3. Use a standard merge algorithm to merge the CatalogueTransaction file with the Catalogue Data File.

4. Update the Catalogue Data File wi th any changes to thesubjects that appear on the Subject Transaction File.

5~ Create the Catalogue Index Fi les ( Author, Ti tle, Subject)/ by processing the Catalogue Data Fi leo6. Sort the Catalogue Index Files.7. For each subject in the Subject Reference Fi le, update the

record offset pointer into the Subject Index File. (Thiswill save binary searching the Subject Index File.)

8. Copy all the new files into position for use in the system.

The Borrower Update sequence (L020402.sh) is a sequence of SIX (6)procedures that wi II update the Borrower Data File fromthe transact ion fiLe and recreate the Borrower name IndexFile. The sequence steps are :-

1. Copy all files to a backup copy for safe keeping.2. Sort the Borrower Transaction file by borrower number and

datel time of transact ion. Select only the latest transact ionfor each borrower and rewrite the transaction file.

3. Use a standard merge algori thm to merge the Borroweransaction File with the Borrower Data File.

4. Create the Borrower Name Index File by processIng the

IBorrower Data File.

5. Sort the Borrower Name Index File.6. Copy all the new files into position for use in the system.

The On Loan Update sequence <L020403.sh) is a sequence of four(4)procedures that will update the On Loan data File fromthe transaction file. The sequence steps are :-

1. COpy all files to a backup copy for safe keeping.2. Sort the On Loan (daily) Transaction File by i tern_number I

copy_number and date/time of transaction. Select only thelatest transaction for each i tem_number/copy_number andrewrite the On Loan (daily) Transaction File.

3. Use a standard merge algorithm to merge the On LoanTransaction File wi th the On Loan Data File and carefullydetect any exceptions.

4. COpy all the new files into posi tion for use in the system.

L020404.sh runs all these updates processes.

To check that these updates have run and completed successfully thelibrary manager must exi t from the LIES system and examine a UNIX file.When an update is submi tted informatory messages are piped from theshell procedure into a UNIX file of the name

"the prefix of the shell fite".lis.For instance the catalogue updates go to

L020401.lis.A message will appear for each of the steps signifying it completedsuccessfully. When the entire procedure has completed successfully themessage

'''filename'' update completed successfully'will be the last message displayed. If this does not appear then thelast step completed can be detected from the messages and the userwill know the problem occured somewhere in the following step. For moreinformation the file

If the pre f j x 0 f the she l l f'i l e" . e n-will contain furhter messages pinpointing where the problem occured.

If any update fails to complete all steps successfully j t will the olddata can be recovered by copying the backup files back into the originaldata files. All backup files have an extension of .OLD.

3. USER INTERFACE

The L.I.E.S user interface is entirely screen based. All userinteraclion with lhe system is via menus or screen functions.

3.1 SCREEN HANDLING

Screen handling is controlled by the CURSES package. It pet-mits theprogram to posi t ion text on the screen, to pas; t ion the CUt-sOtappropriately for the input of data fields, and to allow the movementof output fields, messages and highl ighted fields to the screen.

To maintain consistency and ease of operation, a standard screenhas been used in the L.I.E.S system. ( APP 11.3).A set of standard control keys are also used throughout the system.These are:

CNTL-ACNTL-CCNTL-ECNTL-PTABRETURN

Corresponding to all input screens is a data structure SCREEN_CURRENT, where lhe input from the screen is stored forsubsequent processing. All input to the screen is placed initially incharacter fields. Data which is required to be numeric is then checkewhether numeric and converted to its corresponding numerIc field usinEDIT_CONV_INT. Each screen containing numeric data Will also have anumeric screen data structure corresponding to its string/characterdata structure. Integer fields are stored in this structure to bepassed to the processing phase of the function.

1 FIELD INPUT

All input of fields is handled by a common function - GETFIELD. Tilfunction is invoked by:

code_return = GETFIELD ( field, length)field = current screen field or data item.length = length of field in characters.code return - GETFIELD wi II return a code to indicate the type a

control key used to terminate the input field. Itmay be set to the values

CD_RETURN, orCD_CANCEL, these are initialised in the

constants file - constants.h. This field may thenbe c he c ked by the cal ling fun c t ion t 0 see how i tshould proceed.

field - upon return to the call ing program it will contain whathas been input to the screen by the user. If no validcharacter input was entered or the field was blanked outor cleared it will contain a null character.

- DEL- HOME- ESC- CLEAR

All characters typed on the screen are filtered by GETFIELD. Thisis achieved by setting the terminal device in RAW mode. Thus, ratherthan characters such as QUIT, interrupt and suspend generating asignal the characters are passed through uninterpreted. This allowsthe function total control over what the user types ( ego the usercannot break out of the system ).

All characters are converted to upper case. This bypasses anyambiguity associated with searching on upper or lower case fields.

When a field is terminated GETFIELD returns the characters tvoedinto that field to the calling function. GETFIELD will be terminatedin one of 5 ways:

- detection of TABterminates the field and returns to the calling function.

- detection of RETURNreturns to the calling function and sels lheglobal field code_return to CD_RETURN so the calling functIoncan recognise that screen input has been terminated.

- detection of CNTL-Eresets the terminals to normal operating mode and exi ts thecurrent process back to the process that invoked it. Uses theUNIX system command - exit.

- When the fie l dis fullreturns to the calling function.

- detection of CNTL-Creturns to the calling function-and sets code_return toCD CANCEL so the calling function can recognise that screeninput has been cancelled.

FIELD EDITING

GETFIELD allows various edi ts to be performed on the field bv theuser. The CURSES package allows the following keys to be recognisedand GETFIELD determines what function is to be performed whenthe key is pressed:

- BACKSPACE delete last character typed- LEFT ARROW : as for backspace- RIGHT ARROW: moves the cursor right until the last character

of the field is reacheddelete current charactermove to beginning of fieldclear to end of fielderase entire field and place the cursor at thebegining of the field.

It is possible to recognise the DEL and ESC keys because the deviceis set in RAW mode.

1

VALIDITY CHECKS

GETFIELD checks for a set of valid characters. These include anysingle character which can be typed from the keyboard, and the help(CNTL-A), exi t (CNTL-E) and cancel (CNTL-C) control keys. Leadinablanks are ignored for any field longer than one character. Trailingb l an k s are t r i mne d be for e the fie l dis ret 1I r ned. An' I NVALID KEY'message is issued if any other key is hI t.

3.2 INPUT DATA COLLECTION

The collection of input is concerned with collecting the user inputfrom the function's input screen and placing it in the screen datastructure to be passed on for processing. All screen function performthe same basic processing in this area. screen function.

Once a screen funct ion is invoked the input screen for thatfunction is displayed to the user. On all the functions the cursorwill initially be positioned at the first input field for that screen,awaiting user input. Simple field validation is handled by placinga loop around the retrieval and consequent validation of the field.Whi le the val idat ion requi rements for that field are not met or thecancel key or function termination keys are not hit then the cursorwill be positioned back at that field and a sui table error messagedisplayed, until it is valid. The field terminator (TAB key)therefore, cannot be used to pass by afield unt i l the data input intothat field is val ide

Once the inputted field is valid the cursor is placed at the nextfield which requires input, moving from left to right and down thescreen. Once the last field has been input, the cursor IS placed backat the first input field. This wrap around effect is achieved byplacing the collection of the entire screen data within a loop. Thisloop is terminated when the use of the submission key IS detected.When the cancel key is detected as input the function will break fromany validation loop it may be currently in, clear all the input fieldsand return to the top of the loop ready to accept the first inputfie 1d.

3.3 SECURITY

Access to the Librarian and Manager functions is restricted Inorder to prevent misuse by unauthorised users. Two methods ofprotection have been employed:

- "hidden" access method.- password protection.

HIDDEN ACCESS

To deter the curious user, instructions on how to access therestricted functions are not given in the L.I.E.S logo screen.

PASSWORD PROTECTIO~

The password for the Manager and Librarian functions can be different.Two programs:

L0102.0 ChecK_manager_authori tyL0103.0 ChecK_l ibrar-jan_authori ty

are used to check security. The current password is stored In anASCII file. The password entered on the Enter Password screen is readby the function GET-PASSWORD which operates similarly to GETFIELD(see later explanation) except any characters entered are notechoed. Another two modules:

L0206.0 Change_manager_passwordL0305.0 Change_Librarian_password

are used to change the password after accessing the required function.

3.4 ON-LINE ASSISTANCE

L.I.E.S offers the user assistance in 2 ways:- Full screen help- Informative messages

HELP SCREENS

Each screen has an associated help screen which can beinvoked by pressing CNTL-A. This invokes the function HELPINFO whichdisplays a screen structure - HELPWIN - over the current window.

The help screens are stored in ASCII files with one file per screenfunction. The files are up to 80 characters wide and can be as long asnecessary. The text can be paged through one screen at a time. A blockof seventeen lines makes one page. The first seventeen lines are readfrom the help file and displayed. Pressing the space bar causes thenext 17 lines to be read and displayed. At end of file, pressingRETURN returns control to the calling function and its screen IS

redisplayed.

Each screen is given a unique identi ty which is defined in thesystem constants file. This identity allows the help function todetermine which help file to read. SCREEN_IDENTITY is a globalvariable available to all procedures called by the screen functionit must be set to the ident i ty for the help requi red at the time.

For a list of help file names see APP 11.5. The names have anextension of .HLP and a file name associated with the unique screeni den tit y.

INFORMATIVE MESSAGES

All error messages generated by L.I.E.S functions are displayed online 2 of the screen and highlighted in reverse video. An alarm IS run( ie beep) when an error occurs. Any informative messages for theuser are displayed on line 3 in a similar fashion.

4. MAINTENANCE FUNCTIONS

OVERVIEW

The library manager is responsible for performing the updates on thedata files within the LIES system. In order to do this he/she IS

provided wi th a number of maintenance programs and to veri fv the fileshe/she has the option of producing reports. .

Three maintenance functions are provi~ed in the LIES systemare :-

MAINTAIN CATALOGUE INFORMATIONMAINTAIN BORROWER INFORMATIONMAINTAIN SUBJECT REFERENCE DATA

For consistency the functions share common fields and process.no.The TRANSACTION_CODE field on the screens allows the user to nomin;tethe process he wishes to perform. The alternatives are :-

for DISPLAY'C' - for CREATE'0' - for DELETE'u' - for UPDATE

If a DISPLAY is required, only the screen key field must be entered,ie. ITEM_NO for catalogue displays, BORROWER_IDENTITY for borrowerdisplays and SUBJECT_IDENTITY for subject reference displays. In thecase of a DISPLAY, the programs restrict movement of the CUt"sor to theTRANSACTION_CODE field or screen key field only.

In CREATE mode, the user is able to enter all fields on the sct-een.

In order to UPOATE records the user must first DISPLAY the record.The process was designed in this way so as to provide an extra safetymechanism to the user. By displaying the record fIrst he can be certaInat a glance that he is updating the correct data. Also, al tering thefields ;5 made easier as he can see what the record currently lookslike and simply type over the data in question. In this case batchprocessing i~ simpl ified as well since ,n an UPDATE si tuation the fullrecord is wr it ten to the transact ion file not just the fields that werealtered.

If the user types in a 'u' for UPDATE without having done asuccessful OISPLAY the cursor wi II remain at the TRANSACTION_CODE fieldand display an error message. Once a successful OISPLAY is achieveqthE: user is able to al ter all fields on the screen except for thescreen key field which is protected by the function.

In order to OELETE records the user must first DISPLAY the record. \As described above, this is to provide safety mechanisms to the users ..I t is hoped that thi s wi II reduce erroneous deletes by the user.

For a DISPLAY, a binary search using the approprIate BINSEARCHfunction is performed on the data file. Since the TRANSACTION file IS

not sorted and we require to locate the most up to date record for theitem, a sequential search is conducted on the TRANSACTION file. Thus ifa record is found on the TRANSACTION file then it is displayed,otherwise if a record is found on the CATALOGUE file then it IS

displayed else an error message is returned.

For a CREATE or an UPDATE or a DELETE a record is wri tten to theTRANSACTION file for batch updating. Refer structure of theTRANSACTION file (Appendix 11.1). A time stamp is put on the record asit is required by the batch updating program. The data entered by theuser or the deleted record remains on the screen and an informatorymessage is displayed. This is done so that in cases where the user hasmade an error he may notice it straight away. For a DELETE on aBORROWER or a CATALOGUE record if the record is in some way linkedto en ONLOAN record the function will not permi t the deletion in orderto maintain file integrity. Similarly a SUBJECT record may not bedeleted if it has children.

Compulsory. Must be numeric and non-zero. Thefunction EDIT_CONV_INT is used for validation.

At least one must be entered. The global functionVAL_SUBJ_TAB is used to veri fy if the subject ispresent in the predefined subject list. If theSUbjects entered cannot have a parent-childrelationship so the global function CHECK_PARENTis used to verify this. If the user blanks out asUbject the function will shuffle remainingsubjects to the left.

This involves checking that all compulsory fields have been inputted i

and that the combination of subjects entered is valid. This is required;in certain cases where only part of the data has been entered or •altered. For instance, during a CREATE, if the user presses RETURN afteentering the title of an item, the program must ascertain jf theremaining fields had been entered as well.

SUBJECT

PARENT

DESCRIPTION

Unless in CREATE mode the subject entered must bepresent in the predefined subject dictionary.If in CREATE mode the program checks if thesubject entered already exists.

The parent can only be entered during CREATE modeand the subject must be in the predefined subjectdictionary.

Not compulsory. Can be entered during CREATE modeor altered during UPDATE mode.

For a DISPLAY, the parent and description for the subject entered isretrieved from the subject table.

For a CREATE, the function determines whether the subject created IS

the only one for that particular parent by checking if CHILD_POSITIONis NULL. This is required in order to update the respective pointersin the subject tree. The new subject is also added to the subjecttable.

For an UPDATE, the user is able to change the spelling of a subjectby first displaying the subject and then updating it. The function willthen change the old subject to the new subject. A record is alsowritten to the SUBJECT TRANSACTION file far batch updating on theCATALOGUE file.

For a DELETE, the function will delete that subject from the subjecttree, update any pointers that were affected and remove the subjectfrom the subject table.

When the function is exi ted, the SUbject Reference Table on discmust be rewritten with the new version from memory, so that next timea function sets up the array from the file on disc they will be gettingthe updated tree. To achieve this GETFIELD cannot be used toread in the SUBJECTS from the screen since on detection of the exi t keyit will perform the exit to the invoking process wi thout returningcontrol to L0203.c. A new procedure GET_SUBJECT is used (seedescription in section 6. of this report>. GET_SUBJECT upon detectionof the exit key, terminates,the field and sets CODE_RETURN to CD_EXIT.L0203.c may then check this and upon exi ting rewrite the file on disc.

5. RETRIEVAL FUNCTIONS

The Retrieval Functions enable the user to retrieve informationabout items or borrowers using a variety of non-unique searchcriteria.

The Collect Input phase of this function varies from all otherfunctions in that it provides an assisted subject selection facility tothe user. This is contained in the procedure ASSISTED_SEARCH. which IScalled from the COLLECT_SEARCH_CRITERIA • if a '?' is detected in thefirst subject field of the screen, provided no other subjects have:beenentered.

A STACK is used to store the selections of the user. TheSTACK is set at five (5) elements which allows it to function on aSubject Reference Tree of six levels counting the root level. Curl-entlythis is ample, any increase in the number of levels thus will mean thisSTACK_SIZE must be increased. The standard POP. PUSH and INITIALISEalgori thms are used to manipulate the stack.

Currently, the subject field IS fifteen (15) characters, thisenables us to display four (4) of them across the screen, on eIght (8)'lines and thus we may display thirty-two (32) subjects. This places alimi tation of this amount (32) on the number of subjects which may'occur on each branch of the tree. This amount at present IS ample andwe believe should remain so for the size of the library we envisage. Ifmore than thirty-two (32) subjects on a branch is reqUired then I t IS

not an easy matter to display more. It either means a reshuffle of thescreen to supply more lines to display them on or a decrease In thesize of the subject field to fit more on each line. If a need toIncrease the size of the subject field arises I t should so be notedthat we may not be able to fit as many on the screen and so the llml ton the number of subjects on each branch of the tree IS decreased. Thusa trade off between subject field size and the number of subjects oneach branch of the tree is required.

VERIFICATION (performed in L04.c)

Ei ther the title, the author surname or at least one subject mustbe entered. Searching is only performed on the lowest child of eachbranch of the tree.

CHECK_SUBJECT

The global CHECK_PARENT is used to check whether one subject IS adescendant of another and if so only the descendant will be wri tteninto a searchable subject structure, this is then checked against thethird subject, and if one is a child then only it is written to thiSstructure. If none are descendants then all are searched on. This is toavoid repeti tive searching since a search performed for items on asubject also retrieves all the items for its descendants. When thesearch results for a subject and for its descendant are anded togetheronly the matches for the descendant will result anyway. The procedurewhere this is performed (CHECK SUBJECT) is complex but is well

commented and should so be easy to follow.

L0402.c PROCESS_SEARCH

Since a combination of search criteria is treated as a conlunctlvesearch it is necessary that when the matches for one criteria"are foundthat the posi tion number of these matching records in the CataloQueFile be stored to see whether they are also matches for the othe;criteria. This is achieved by placing the posi tion nwnber of the match,n a BINARY SORT TREE along with a counter which is incremented eachtime that position number is seen to match one of the criteria. Onceall the cri teria have been searched on, the tree IS traversed and onlvthose which have counters equal to the nwnber of search crl teria are·retrieved from the Catalogue file and written to the Output file.Alltree accessing is achieved using recursive functions, REAL_TREE andREAL_TRAVERSE the algorithms of which are the standard form.The tree is dynamic, each node allocated when required and thus asmany subjects as required may be stored in it.

The processing for a Subject search di ffers because the Sl tuationexists where an item is claSSIfied under multiple subjects. Forinstance, if a search is performed on "DATA" and j tem "AYt has beenclassi f ied under the subjects "DATABASE" and "DATA STORAGE", two ofthe chi ldren of "DATA", it wi II have two occurances on the SUbjectIndex File which will both be retrieved as a possible match for "DATA".This means the count on the tree for this 1 tem will be Incremented totwo (2), even though we are only looking for those WI th a count ofone (1) since we only have one search cri teria. To overcome thiSa seperate function for plaCing subject matches In the tree(TREE_SUBJ) is ut i l ized. It makes use of an array of three (3) flags(FLAG_SUBJECT) which are used in conjunction WI th the tree to slgnl fywhether that j tem has already been found for the searchable subject weare currently examining.

L0403.c DISPLAY RESULTS

Straight forward read from Output file and display to the screen ofthree (3) records at a time. Scrolling up (the up arrow) is simplydone by an LSEEK back through the file six (6) records, the next three(3) records are read and moved to the screen. The print key provides ahardcopy of the entire Output file by system call to a SHELL file whichsubmi ts the pr int funct ion (L040301.c).

OUTPUT STRUCTURE

Like the Catalogue record.

5.2 L0303.c

OVERVIEW

BORROWER INFORMATION RETRIEVAL

The aim of this function is to provide quick retrieval ofinformation on a borrower including there number, name, addressand the items they have on loan and when they are due to bereturned. The function is devided into four (4) functionallyindependant modules. Namely-

1) Collect Search Criteria (L030301.c)2) Process Search (L030302.c)3) Display Results (L030301.c)4) Display Mult Res (L030301.c)

The mainline (L0303.c) performs the veri fication of input beforecalling Process Search.

L030301.c COLLECT SEARCH CRITERIA


INPUTBORROWER NUMBER

BORROWER NAMESURNAME

GIVEN NAME (1)

GIVEN NAME (2)

OUTPUTBORROWER ADDRESS

STREET NUMBERSTREET NAMESUBURBPOSTCODE

ITEM DATA (10)ITEM NUMBERTITLEDATE DUE BACK

Must be numeric and non-zero. The functionEDIT_CONV_INT is used for verification.Only allowed to enter if BORROWER SURNAMEis blank.

Only allowed to enter if BORROWER NUMBERis blank.

Only allowed to enter if BORROWER SURNAME nonblank. If the SURNAME is blanked out by the userthen the function will blank this field also.

Only allowed to enter if GIVEN (1) non blank. Ifthe SURNAME field or the GIVEN (1) field areblanked out by the user then this field will beblanked out by the function also.

VERIFICATION (performed in L0303.c)

Ei ther the borrower number or borrower surname must be entered forthe search.

L030302.c PROCESS_SEARCH

When the BORROWER NUMBER is input the record is retrieved bv dOlna ahbinsearch on the Borrqwer file. If the borrower has i tems onl~an th;nfor each item the Onloan file is binary searched. If the Onloan t-ecot-dfor that item is not located then it is assumed that it was borrowed onthat day and the DATE DUE BACK on the output data structure is made thecurrent date plus seven days. If the record IS located and the borrowerIdentity on it is blank then the i tern has been returned today and so ISnot displayed. The Catalogue file is then binary searched, if therecord is not located then a file error IS assumed and appropriateact ion taken. The requi red data from all the records IS wr I t ten to theoutput record and the output record wr I t ten to the output file.

When the BORROWER SURNAME is Input then the Index file must beaccessed first and any matching records found here are then retrievedby doing an LSEEK on the Borrower file to the offset on the IndexIf only one record is found matching then processIng contInues asabove for the BORROWER NUMBER. However, I f more than One match IS

located then for each match only the data from the borrowerrecord is wri tten to the output structure and subsequently to theoutput file. This avoids extra file accessing on the Onloan andCatalogue files when the user is unsure which b~rrower they actuallyrequire the data for. Supplying the borrower data enables them todecide which borrower they actually wanted and then resubmi t the searchwi th that BORROWER NUMBER for that borrower.

L030301.c DISPLAY RESULTS

If one record is retrieved then this Output phase reads the outputrecord from the output file and moves it into the screen outputstructure and displays it on the screen. A print is provided callingthe print function (L030303.c).

If more than one record has been retrieved then the output fiLe IS

treated in the same way as in CATALOGUE INFORMATION RETREIVAL describedpreviousLy, except one record is displayed at a time. There is noprint key provided in this area The submission key is accepted, and if nit is input than the PROCESS_SEARCH is recalled this time wi th theBORROWER NUMBER.

8. CIRCULATION FUNCTIONS

The librarian is responsible for performing the daily duties of thelibrary. In order to do this he/she is provided wi th two circulationprograms these being BORROW AN ITEM and RETURN AN ITEM.

6.1 L0301.c BORROW AN ITEM

This process allows the librarian to enter informatIon about an I ternbeing borrowed, to be kept as a record of the transaction.


Compulsory. Must be numeric and non-zero.



VERIFICATION

Checks borrower exists and has less than the maximum number ofbooks onloan (10).

Checks the item exixts and is not presently onloan.If it is onloanthen it is up to the librarian to investigate the discrepancy.PROCESSING

To ensure up to date information on the CATALOGUE file and BORROWERfile on-line updating is performed.

Number copies borrowed on the Catalogue file is updated immediately.This is important as users requesting catalogue data by uSIng theRETRIEVE CATALOGUE INFORMATION function will know exactly how "manycopies are available in the library.

Items on loan on the Borrower file is also updated immediately Inthe same manner. Number items on loan is incremented and the j ternborrowed is inserted in the list of i terns borrowed by that borrower.This it so that borrower information displayed using the RETRIEVEBORROWER INFORMATION function is accurate and that; f the 51 tuationarises that a borrower has the maximum books on loan he/she IS ableto return a book and borrow another book on the same day.

A record of the transaction is wri tten to the DAILY TRANSACTIONfile for batch processing. During batch proceSSing any Integrl ty errorsare reported.

6.2 L0302.c RETURN AN ITEM

This process allows the librarian to enter information about an iteJbeing returned.-)


COpy NO

VERIFICATION


Compulsory. Must be numerIc and non-zero.

Check to see if the item is presently onloan.Check the item exists.Check the borrower reported to have the book exists and has thatbook onloan.

PROCESSING

Uo to date information is also achieved in this funct ion asdescribed in the BORROW AN ITEM function.

Number copies borrowed on the CATALOGUE file is decremented.

Number items on loan on the Borrower file ;s decremented and theitem returned is removed from the list of items borrowed by thatborrower. The function will shuffle any remaining items to the top ofthe list if need be.

The ON LOAN file is also updated immediately. The borrower identItyfor the record is blanked out so to indicate that the item wasreturned today.

A record of the transaction is wri tten to the DAILY TRANSACTIONfile for batch processing. Any integri ty errors are reported bybatch processing.

7. REPORTING FUNCTIONS

The L.I.E.S systems provides the facility to generate seven (7)reports. The CATALOGUE. BORROWER, ON-LOAN and OVERDUE reports aresubmitted via the MANAGEMENT REPORTS menu. The SUBJECT DEFINITIONSraoort is submitted from the LIBRARIAN FUNCTIONS menu. The remalnlnatw~ reports can be generated by the print key ( CNTL-P ) on the display catalogue results and display borrower data screens.

When a report request is issued a batch program IS su~nltted andIts output is piped to the printer. To supress the UNIX system messagewhich is issued when a print request IS made the -s option IS used onthe lp command. An informatory message IS displayed to tell the userthe report has been submitted and he/she can continue working.

8. GLOBAL FUNCTIONS

The L.I.E.S system has a number of functions used In severalprograms. Two of these ( GETFIELO & HELPINFO ) have already beendiscussed in detail.

BINARY SEARCH

There are six (6) binary search functions. Each searches adifferent file. These files are:

CatalogueBorrowerOn-LoanAuthor IndexTitle IndexBorrower Name Index

Usage:

CAT_BINSEARCH( j tern_number)item_number = unique key to Catalogue File

BORROWER_BINSEARCH( identity_borrower)identi tY_borrower = unique key to Borrower File

ON_LOAN_BINSEARCH( i tern_number, copy_number)item_numbercopy_number = combine to make a unique key of the On-Loan

f i l e.

AUTHOR BINSEARCH{ surname >surname = non-unique key to Author Index File

TITLE_BINSEARCH( title)title = non-unique key to Title Index File

NAME BINSEARCH< surname )surname = non-unique key to Borrower Name Index File

Description:

Each of these functions performs a binary search for the datapassed, on a specific file. In cases where the data occurs more thanonce the first occurence is ,-eturned. If the data is not found thefunctions all return the value -1. If the data is found the record IS

stored in a data structure defihed in the calling function. TheCAT_BINSEARCH, BORROWER_BINSEARCH and ON_LOAN_BINSEARCH functions usethe file descriptor from the calling function and leave the filedescriptor at the current position in the file. This posi tion is usedin programs which perform direct updates on files (eg. borrow anitem ). The program can return to the correct postion in the file torewri te the record. The remaining three return the number ofcharacters last read.

Usage:CALC_DATE ( string)

string = a 12 character string in which currentdate and time is returned

Description:

This function returns todays date and time in the form DO MMM YYHH:SS. The current date value is obtained using the UNIX system callTIME() which returns a long integer value for the current date andtime. This value is converted to a 26 character string using the Csubroutine CTIME(). The string returned is substringed to the 12characters required.

CURRENT_YEAR

Usage:

n = a 4 digi t inteaer containing the value of thecurrent year.

Description:

This function returns the vear in the form YYYY. The current yearvalue is obtained using the UNIX system call TIMEC) which returns along integer value for the current date and time. The C subrout,neLOCALTIME() is used and returns a pointer to a structure containingthe year in the form YY. The function then adds 1900 to the yearvalue.

SUBSTR

Usage:SUBSTR( sl, s2, start, len)

51 = string returned52 = string to substring

start = post ion to start substring In sllen = Length of string required

Description:

This function returns a string of length LEN which is part of thestring s1.

Usage:

sl = string to convertlen = length of string sl

x = integer returned

Description:

This function converts a string of numbers sl into its equivalentinteger value. The string is first edited to make sure j t containsonly valid digits and is correctly terminated wi th a NULL (ie \0 ). Ifthe string is valid the C function ATOI is used to convert the stringto an integer.

ITOA

Usage:I TOA ( n. s 1 )

n = integer to convertsl = converted string

Description:

This function converts an integer into a character string. ReferC Programming Manual for details.

GET SELECTION

Usage:code_return = GET_SELECTION( field, length)

fie l dlength

= the selection field.= length of field in characters.

CODE RETURN

Description:

GET_SELECTION will return a code toindicate the type of control key used toterminate the input field. It may be set tothe values

CD_RETURN, orCD_TOP,CD_BOTTOM,CD_CANCEL, these are initialised in the

constants file - constants.h. This field maythen be checked by the calling function to seehow it should proceed.

Operates similarly to GETIELD but accepts a numeric selection fora subject in the ASSISTED_SEARCH procedure of L0401.c.It terminates the field and may set two extra values in CODE_RETURNif the up arrow (CD_TOP) or down arrow ( CD_BOTTOM) keys arepressed.

Usage:code_return = GET_SUBJECT ( field, length)

fieldlength

= current screen field or data item.= length of field in characters.

CODE RETURN - GET_SUBJECT will return a code toindicate the type of control key used toterminate the input field. It may be set tothe values

CD_RETURN, orCD_EXIT.CD_CANCEL, these are ini tialised In the

constants file - constants.h. This field maythen be checked by the calling function to seehow it should proceed.

Description:

Operates similarly to GETIELD but returns the code CD_EXIT WhenCNTL-E is pressed instead of returning to the calling process. ThISfunction is used in the L0203.c the Maintain Subjects function. Thefunction rewrites the Subject Reference File before eX; lIng.

Usage:CHECK_PARENT <parent1, parent2, child1, child2)

paren t 1 = posi tion of the subject to be checked currentlyparent2 = pos it ion of the original subject to be checked

as parentch i l d 1 = position of the first ch i l d of a subjectch i l d2 = position of the subject to be checked as ch i l d

FLAG_PARENT must be declared globally by the function calling CHECK_PARENT and initialised to zero (G)pr ior to each call. I t wi II then be set to one(1) by CHECK_PARENT if parentage is detectedand so may be checked on return to the callIngfunction.

On the ini tial call to CHECK_PARENT then parent1 and parent2should both be set to the subject we wish to see IS anancestor. Child1 and chiLd2 should be the subject we wish tocheck as the descendant.

Description:

This function verifies if two sUbjects have a PARENT-CHILOrelationship.The aLgori thm would be as foLlows:-

If the subject to be checked currently equals the original childto be checked then

Found to be descendant set FLAG_PARENT

If the subject to be checked as parent has children thencall CHECK_PARENT with the child pointer of this subject

the original subject remains the samethe child pointer of this subjectthe original child to be checked remaInsthe same

If the subject to be checked as parent is not the original subjectand the subject to be checked as parent brother pointer doesnot equal the position of the first child then

call CHECK_PARENT wi th the brother pointer of this subjectthe original subject remains the samethe child pointer remains the samethe original child to be checked remaInsthe same

Usage:flag-valid =VAL_SUBJ_TAB (subject, posi tion, level)

subject = the input subject field to be checkedposition = if the subject found returned as I ts Position

in the table else zero (0)level = if the subject found the level number of the

subject in the tree as stored on the table elsezero (0)

flag_valid - VAL_SUBJ_TAB returns a flag, zero(O) ifsubject was not in the tree and one (1)was.

Description:

thei fit

This function checks whether the passed subject is found in theSubject Reference table. It simply loops through the table elementschecking if they equal the one passed. If a match is found thenone (1) is returned to the calling function and the position and levelnumbers set, else zero is returned and posi tion and level set to zero.

9. MAINTENANCE

All programs contain a condi tional test for flag-debug, as definedin the system constants fi leo When the flag is switched on messagesare written to standard error. These messages provide a trace of theexecution of programs and assist in locating bugs.

When any changes are made to a module In the system a file IS

provided ( MAKEFILE ) which recompiles and relinks all L.I.E.S modUles.To recompile after changes are made type

MAKE LIES

All constants for the system have been placed in a single fileconstants.h which is included in the top of all programs. To change thevalue of any constant field this file need only be updated and theMAKEFILE executed to incorporate the change into all programs.

The length of any field may simply be varied in the above fashIon,however care must be taken to ensure it does not upset the format of anyscreens or reports which require it. The length of the Subject fIeldhas the added restriction placed on it by the ASSISTED SEARCH procedure,which is stated in section (5.1) of this report.

It should be noted that the length of all string fields have beendeclared as one longer than the length speci fied in the constants fi Le.This is due to a requirement of the C Programming Language that strIngfields have a null character at the end. For ease of string maipulatlonwe simply declare the string fields one character longer than reqUiredto cater for this null character.

10. FUTURE ENHANCMENTS

The present implementation does not perform the followingfuncl ions.

* Fines processing* Reservation processing* Closed Reserve processing* Backup and .,Res tor e capab i l j t as.

However, interfaces to these functions have been catered forIn the design of LIES, and the current file desIgn will not needto be changed to implement these future enhancements. For moreinformation refer to the Systems Analysis document.

It would also be possible to make use of a barcode reader I.n theBORROW AN ITEM and RETURN AN ITEM functions for the Inputting ofborrower numbers and item and copy number.

INTRODUCTION

L.l.E.S. ( Library Information and Enquiry System) IS asystem that has been divided Into three broad functional areas

Borrower- Librarian- Library Manager

These three areas correspond to the three users for whichthe system was deSigned. It IS assumed that the Borrower shouldonly be allowed to perform catalogue Information retrievals; theLibrarian shouLd be alLowed to perform the Librarian functions( pLus the Borrower functions ); and the Library Manager shouldbe aLlowed to perform the Library Manager functions t plus theBorrower functions, and, If need be, the Librarian fUnctions ).

For the above reasons the User ManuaL IS Simi Larlv broken upInto three detachable bookLets, such that the reLevant sectionsmay be distributed to the users Indicated.

Because of the broad spectrum of use/-s L.I.E.S. IS deSignedto accomodate, user frlendL Iness IS essential. For thiS reasonsuch features as menus. help screens, User Manuals and lutorlaLManuaLs have been used to assist the novice. On the other hand.there are many advanced features of L.I.E.S. that WILL alsosatisfy the needs of the experienced user.

As Just stated L.I.E.S. is a menu-driven svstem. lhe primaryme nUl s the L. I . E . S . Logo. From t hIS log 0 any 0 t the j un c t Ion sof L.I.E.S. may be accessed (WI th the correct secur I ty).

L.I.E.S. resides entireLy on the UNIX supported ~yramld

machine and may be qui te simply Invoked by tYPIng "LIES" andpressing <RETURN>. When the L.I.E.S. logo screen IS returnedthe user may Invoke the Catalogue Information Retrieval functionby pressing <RETURN>. To Invoke the Librarian or Library Managertunctlons the user must be aware ot certaIn securl ty practises,an~ so should consuLt the Library Manager I t unsure ot a logonprocedure.

1 t the user presses any other key then a heLp screen WILL bereturned to Instruct the user on how to enter L.I.~.S..

Page ~

Unce the user has entered L.I.E.S. there are a number 01

screen handling features that should Ilrstly be understoodbefore you can gain maximum efficIency from the L.l.E.S. system.A brief description of most of these features IS given below butIff ur t her In forma t Ion I S needed I tiS sugges ted t ha t youconsul t the Tutor I al Manual.

To move around the screen use the <TAB> key to move tromfield to field and the left and right arrow keys tor movementswithin a field. When the cursor IS placed on the field where youneed to enter data you may begin typing. 11 you make a mIstakethere are a number of ways In which you can correct the error.Firstly, you can move the cursor back to the error (by uSing theleft or right arrows) and then simply overtyplng the error.Other alternatives could include a combination of tabbing andother features listed below.

To erase a character the user should use the delete key andif he/she wishes to erase the whole field he/she can use the<ESC> (erase screen component) key.

To posi tion the cursor at the beginning of a field the usershould press the <HOME> key.

To enter a funation from a menu the user should simply typein the appropriate number for that function. (NOTE: there IS noneed to press <RETURN> after entering your selectIon). Thefun a t ion will the n be ret urne d rea d y for you r use. Toe x I t fromthe function to the menu screen the user should press <CNTL-~>

<EXIT). <To use a CNTL-key hold down the <CNTL> key and pressthe character you require).

At any time i f t he user requ i res he l p on how t a use thefunction they see in front of them they may call up a brieftutorial (help screen) by pressing <CNTL-A> (ASSIS1).

1. CATALOGUE INFORMATION RETRIEVAL

The Catalogue Information Retrieval function enabLes the userto enter and effect a search on Library cataLogue I terns.CataLogue I terns may IncLude any source of Inlormat Ion that ISkept In the Library no matter what the lonn. <'Ie. couLd Includebooks: SOftware, magazines, JournaLs: tapes: etc.>.

fhe function IS not security protected, as ,t IS envIsagedthat anyone mIght want to use thiS lunctlon to retrieveInformation on Items In the Library.

fo access the CataLogue Information RetrievaL lunctlon SimpLyhi t <RETURN> or <ENTER> on the L.I.E.S. logo screen. ThiS WI LLthen return the Catalogue InformatIon Retrieval screen ready loryour use.

lhe user can perform a search on i terns WI thin the Library byspecifying what sort of Information he/she 50 requires In thegiven fIeLds. A search may be performed on any of the lollowlngcriteria (or a conjunction thereof):

- Author

- Ti tle

- Medium

the author surname and optionally the givenname ( s) 0 r I nit I a l ( S ) .

the exact tItle name.

the type of Item (Ie. book, tape, Jour-nal, etc),

- Date Published: greater than (or equal to) a datepUblished, less than (or equaL to) adate publIshed, or a range of dates.

- SubjecJ a list of up to three (3) sUblects thatWill be used conjunctionally.

Note Medium and Date Publ ished must be In conjunctionwith one of the other search crIteria.

Searches o~ a particular Author and/or TI tle (which may berestricted by Medium and/or Date Publ ished) are straIght lorwardIn that you have asked for something qUl te specl flc. Such asea r chI S c ommo n p laceta the reg u l a r lib r a ,- '! use r bec a use t hislnformation may have been available (although not nearly asqUick) by uSing the old cards system. L.l.E.~. however has anadded feature that will allow the user to r-etrleve Information ona specified SUbJect. It is thiS feature that will be explained Ing rea t e r de t ail bec au s e I tiS some t h I n g t hat nee d 5 mo r eunderstanding In order to operate It effiCiently.

Paae 4

The subject search enabLes the user to ask for aLL materialon a certaIn subject, however, the user must know what sUbJectsare aLLowabLe. L.I.E.S. conJalns a sUbject tree, whereby, apredetermined List of subjects is set up for the user to choosefrom. To view this subject tre$the user has two optIons:

1.1 ASSISTED SEARCH

The Assisted Search facility gUides the user through theallowable subjects until he/she finds the sUbJect that will bestSUI t their needs. These allowable sUbjects are kept In what ISreterred to as a 'Subject Tree'. This subject tree IS set up suchthat the higher levels contain the broad subject categories andthe lower down the tree you travel the more specillc the sUbjectsbecome. For example the first level of the tree may contain thesubject 'DATA'. Now the user may view what subjects 'DATA' coversby looking at its chi ldren. One of its children may be 'DATABASE'for which the user IS interested. On viewing I ts children, 'D~

ADMIN' and 'DB STORAGE', the user may then decide that 'Database'was speci f IC enough and so may return back up the tree to select'DATABASE' as the search subJect.

To invoke the Assisted Search faci II ty the user types In a"7' in the first character of the fil-st subject tleld and presses<RETURN>. This will then return the first level at sUb.lects at thesubject tree. Upon viewing the sUbjects In the first level theuser may want to see what sUbjects are contaIned below a gIvensUbJect. ro view the sUbjects below, the user types the numbergiven beside the SUbject he/she wants to peruse In the SUbjectSelect Ion field and presses the 'Oown arrow'. The subJects on thenext level will then be displayed for the user's perusal. 11 theuser wants to move down the tree turther he/she uses the sameprocedure as just described WI th the 'Uown arrow'. When thebottom of the tree IS reached for a subject area a SUI tablemessage will be displayed indicating that no further subjectsexist. It the user wants to go back up the tree he/she simplypresses the 'Up arrow' to return to the prevIous level.

When the user has t inally found the subjectWishes to search on there are two ways In whichthe search of that particular subJect:

INTRODUCTION

L.I.E.S. ( Library Information and Enquiry System)system that has been divided into three broad functional

BorrowerLibrarianLibrary Manager

IS aareas

These three areas correspond to the three users for whichthe system was designed. It is assumed that the Borrower shouldonly be allowed to perform catalogue information retrievals; theLibrarian should be allowed to perform the Librarian functIons( plus the Borrower functions ); and the Library Manager shouldbe allowed to perform the Library Manager functions ( plus theBorrower functions, and, if need be, the Librarian functions ).

I=or the above reasons the User Manual is simi larly broken upinto three detachable booklets, such that the relevant sections

may be distributed to the users indicated.

Because of the broad spectrum of users L.I.E.S. is designedto a c como d ate, use r f r i end line s sis e sse n t i a l. For t his rea sonsuch features as menus, help screens and User Manuals have beenused to assist the novice. On the other hand, there are manyadvanced features of L.I.E.S. that will also satisfy the needsof the experienced user.

As just stated L.I.E.S. IS a menu-driven system. The primarymenu is what is seen as the L.I.E.S. logo. From this logo any ofthe functions of L.I.E.S. may be accessed (with the correctsecuri ty). An example of the L.I.E.S. primary menu logo screencan be seen in Figure S-01 overleaf.

L.I.E.S. resides entirely on the UNIX supported Pyramidmachine and may be qui te simply invoked by typing "LIES" andpressing <RETURN>. When the L.I.E.S. logo screen is returnedthe user may invoke the Catalogue Information Retrieval functionby pressing <RETURN>. To invoke the Librarian or Library Managerfunctions the user must be aware of certain security practises,and so should consult the Library Manager j f unsure of a logonprocedure.

If the user presses any other key then a help screen will bereturned to instruct the user on how to enter L.l.E.S ..

The Catalogue Information Retrieval function enables the userto enter and effect a search on Library catalogue items.Catalogue items may include any source of informat ion that iskept in the Library no matter what the form. (ie. could Includebooks, software, magazines, journals, tapes, etc.).

The funct ion is not securi ty protected, ast ha 1 anyone m i gh t wan t to use t his f unc t ion toinformation on items in the Library.

I t is envisagedretrieve

To acces~ the Catalogue Information Retrieval function simplyhi 1 <RETURN> or <ENTER> on the L.I.E.S. logo screen. This willthen return the Catalogue Information Retrieval screen ready foryour use.

The user can perform a search on items within the Library byspecifying what sort of information he/she so requires in thegiven fields. A search may be performed on any of the followingcriteria (or a conjunction thereof):

- Author

- Ti tle

- Medium

the author surname and optionally the givenname ( s) 0 r i nit i a l (s) .

the e x act tit lename .

the type of item (ie. book, tape, journal, etc).

- Date Publ i shed: greater than (or equal to) a datepublished, less than (or equal to) adate published, or a range of dates.

- Subject a list of up to three (3) sUbjects thatwill be used conjunctionally.

Note Medium and Date Publ ished must be in conjunctionwi th one of the other search cr iter i a.

Searches on a particuLar Author and/or Ti tle (which may berestricted by Medium and/or Date Published) are straight torwardin that you have asked for something qui te speci fie. Such asearch is common pLace to the regular library user because thisinformation may have been avaiLable (aLthough not nearLy asqUick) by using the oLd cards system. L.I.E.S. however has anadded feature that wi II allow the User to retr ieve informat ion ona specified subject. It is this feature that will be explained Ingreater detaiL because it is something that needs moreunderstanding in order to operate it eff iciently.

2

The subject search enables the user to ask for all materialon a certain subject, however, the user must know what subjectsare allowable. L.I.E.S. contains a subject tree, whereby, apredetermined list of subjects is set up for the user to choosefrom. To view this subject tree the user has two options:

i) ask the Librarian for a copy of the subject definitions.

i i) use the Assisted search facili ty (for more informationsee sect ion 1.1 Assisted Search),

The user has the option of getting a printout of theretrieved items. To do this the user must press <CNTL-P> on thefirst page of items retrieved on the screen. For more detai l onthe layout of the report see Figure R-01 <Report Example) givenafter the screen examples following.

There are four (4) simple examples following

Example - An Author search <shown in Figures S-02 to 5-05)

Example 2 - A Ti tle search <shown in Figure 5-06)

Example 3 A SUbject search <shown in Figure 5-07)

Example 4 - A 'combination' search <shown in Figure 5-08)

(Examples of the Assisted search faci l i ty follow theintroduction given in Section 1.1 Assisted Search),

These examples are for tutorial puposes and explain not onlyhow to request a certain search but some of the screen handl ingand function keys that L.I.E.S. adopts.

A message is displayed to tell the user how many items werefound that met the search criteria (in this case 5 items>. Atthis stage the user may decide that he/she would l ike a hardcopyreport of these items. To invoke a printout the user must press<CNTL-P> {PRINT>. This will then send a printout of the items tothe local printer. An example of a report produced can be seenin Figure R-01 at the end of the following screen examples.

It can also be seen that one of the boOKS has 0 copIesavai lable; this impl ies that this book (or if there is more thanone copy, all of the copies> is currently on-loan.

If the user has found the item that he/she was looking forand does not want to see the next two items then he/she mustpress <CNTL-E) (EXIT), which will lake the user back to theinitial Catalogue Information Retrieval screen. Otherwise, itthe user wishes to view the next two items he/she must press theDown Arrow, which will then display the next screen, as seen inFigure S-05 overleaf.

This is a screen example of the last two items to displayfor the original search criteria.

I t can be seen that the first item appears to be wr it ten bythe author Adams, but upon closer examination you can see thatthe book has two authors of which Abraham is one.

If the user wanted to view those items on the previousscreen then he/she should press the Up Arrow. If the user wereto press the Down Arrow to try and display another screen then amessage will be displayed to say that there are no more items todisplay. What the user must do is press <CNTL-E> <EXIT) toreturn to the Catalogue Information Retrieval function.

If the user had pressed <CNTL-P> <PRINT> this would producea report of the items found. A report example wi th the itemsfound above can be seen in Figure R-Ol following the screenexamples.

1.1 ASSISTED SEARCH

The Assisted Search facility guides the user through theallowable subjects until he/she finds the sUbject that will bestsui t their needs. These allowable sUbjects are kept ,n what ISreferred to as a 'Subject Tree'. This subject tree is set up suchthat the higher levels contain t'he broad subject categories andthe lower down the tree you travel the more spec, f Ie the subjectsbecome. For example the first level of the tree may contain thesubject 'DATA'. Now the user may view what subjects 'DATA' coversby looking at its chi ldren, One of its children may be 'DATABASE'for which the user is interested. On viewing its chi ldren, 'DBADMIN' and 'DB STORAGE', the user may then deCide that 'Database'was speci fic enough and so may return back up the tree to select'DATABASE' as the search subject.

To invoke the Assisted Search facility the user types In a'7' in the first character of the first subject fIeld and presses<RETURN>. This will then return the first level of SUbjects of theSUbject tree. Upon viewing the subjects in the first level theuser may want to see what subjects are contained below a givensubject. To view the subjects below, the user types the numbergiven beside the subject he/she wants to traverse In the SubjectSeLection field and presses the 'Down arrow'. The subjects on thenext level will then be displayed for the user's perusal. If theuser wants to traverse the tree further he/she uses the sameprocedure as just described with the 'Down arrow'. When thebottom of the tree is reached for a SUbject area a sui tablemessage will be displayed ihdicating that no further SUbjectsexist. If the user wants to go back up the tree he/she simplypresse s the 'upar row' tor e t urn tot he pre v i 0 u s level.

When the user has finallywishes to search on there arethe search of that particular

found the subject that he/shetwo ways in which they can invokesubject:

i) Type in the number corresponding to the subject he/shewishes to search on in the Subject Selection field andpress <RETURN>.

) If the user wishes to restrict the search by medium, forexample, he/she must press <CNTL-C> {CANCEL>, to cancelthe Assisted Search faclli ty and then manually Input themedium and the subject to be searched on before pressing<RETURN>.

Examples of various types of searches (including use ofthe Assisted Search facil i ty are given on the pages follOWing>.

2.3 Borrower Information Retrieval

This function will allow the Librarian to retrieve borrowerdata, including a list at items currently on loan tor thatborrower and the date they are due back. The Librarian must enterthe borrower number or the borrower surname (WI th or WI thout theborrower's given name/s or Inl tlals).

Because the borrower number IS a unique Identr ty the lunctlonwill return all relevant data for that borrower. However, aborrower surname may not be unique, and so I f their IS more thanone borrower WI th that surname the Librarian must speci fy whatborrower he/she wants Informat Ion on. Hence, I f there IS morethan one borrower WI th that surname the function Will return themone at a time, lIsting their full given name/s and address. Withthis Information the Librarian can select which borrower hel shewants information for. When the correct borrower IS displayed theLibrarian must then hi t <RETURN>; With the borrower number nowknown the tunct ion Will then return all the I tems that borrowerhas on-loan and the date they are due back.

It the Librarian pertorms a search on borrower name and thereis only one borrower in the library wi th that name thenintormation on what books that borrower has on-loan Will bereturned immediately (Ie. Without the Librarian haVing to hit<RETURN> agaIn).

It any item is overdue then the date due back (on the screen)will be highlighted tor the'Librarlan.

The intormation returned to the screen on the items borrowedj sacandens e d ve r s ion; tog a ina mo redeta i led lis t theLibrarian may request a printed list of the i terns by pressing<CNTL-P> (PRINT) when the j terns are displayed on the screen.

3.3 Maintain SUbject Reference Data

The Subject Reference File is kept in what IS referred toas a 'Subject Tree'. This subject tree IS set up such that thehigher levels contain the broad sUbject categories and the lowerdown the tree you travel the more speci ric the subjects become.For example the first level of the tree may contain the subJect·OATA'. Now below 'DATA' may be the subjects 'DATA STRUCTURES','DATA CODING', 'FILES', 'DATABASE' and 'DATA STORAGE'. Thenbelow 'DATABASE' may be the sUbjects 'DB DESIGN', 'DB MANAGEMENT','DB SYSTEMS' and 'DB ADMIN'. In this example the sUbJect 'DATA'IS the parent of the sUbject 'DATABASE', and 'UATABASE' IS theparent of the sUbject 'DB ADMIN'. This also Implies that thesubject 'DB ADMIN' is a chIld of 'DATABASE', and 'DATABASE' IS achIld of the subject 'DATA'.

The 'root' of the tree is the highest level of the tree andwill not have a parent subject of course; but thiS subJect 11asbeen previously set up In creating the tree. We assume that thesubject 'COMPUTING' will always be the 'root' of the tree and soany SUbject added Will have a parent.

This function enables the Library Manager to MaintainSubject Information and may be accessed from the Library Managermenu by selecting '3'.

When the Maintain SubJect Data screen IS returned the userhas the facility to either:

Display, Create, Update, or Delete a SubJect Record.

(It the subJect being created IS to be afirst level subject then Its parent IS 'computing').

,::\efore a subJect record can be updated I t must be dispLayed.ThiS ensures that the correct record will be processed. Atterthe record has been displayed type a 'U' In the lransactlonIlsLd, make the reLevant changes and press <RETURN>. 1 f theupdates were acceptable then a message Will be dispLayedIndicat Ing that the record was updated successfully; otherWIsean approprIate error message will be displayed.

Before a subject record can be deleted I t must be dispLayed.ThiS ensures that the correct record Will be orocessed.
