Task Outline

Royal Hospital treats patients from a large region. The hospital has three blocks: Patterson Block,Bunyip Block and Curtin Block. Patterson Block is for general patients, Bunyip Block is for childrenand Curtin Block is for intensive care and elderly patients. Patterson Block has three floors (groundfloor, first floor and second floor), with 30 rooms on each floor. Bunyip Block has two floors with20 rooms on each floor. Curtin Block also has two floors, with 25 rooms on each floor. Rooms withineach block can have one, two or four beds. On each floor of Patterson and Curtin Blocks, the first 10rooms are single-bed rooms, the next 10 rooms are two-bed rooms, and all others are four-bed rooms.

In Bunyip Block, the first five rooms on each floor are single-bed rooms, and all others have four beds.

The Administration centre is at the centre of the hospital and covers two floors (ground floor and firstfloor). The main reception, pharmacy and customer advice offices are on the ground floor. All otheradministrative workers are on the first floor.The hospital currently has many database systems, including a Patient database system, a Billingdatabase system and a Financial database system. The Patient database system contains all the

basic information about the patient. The Billing database system is constantly updated by variouspeople as the patient is given treatment or moved around the hospital; for example, nurses andadministration staff can update the database with information about the rooms the patient has been in,the operations they have had, and medication they have received from the pharmacy and whether or

not they have been in intensive care. The Financial database system contains all the costs associatedwith the treatment of patients. The Financial database system is also used for budgeting.When a patient arrives at the hospital, their basic details are recorded by personnel in the

Administration centre into the Patient database system, e.g. name, address and date of birth. Thepatients arrival date is also entered into the Billing database system. Patients at the hospital can betreated for any number of days, and can stay in more than one room over the duration of theirtreatment; for example, a patient may be placed in intensive care for a number of days after anoperation, and then be moved to another room within the hospital. When the patient receives

treatment or is relocated from one room to another, these details are entered into the Billing databasesystem at one of the nurses workstations, which are located on each floor of each block.Patients are billed for their treatment in hospital when they leave. The bill can comprise manyelements, e.g. room charges, theatre fees (if they have had an operation), pharmacy charges (for anymedication they have received), and additional charges for operations requiring special equipment.There is an extra charge per day for patients who have received treatment in intensive care.

All software applications are centrally located on the applications server which is stored in anunprotected section of the Administration centre. All nurses workstations are connected to the servervia a bus network and coaxial cables. The computers at each workstation are now eight years old andrunning an old version of an operating system. This hospital also has two computers in each block forpatients to browse the internet.

A consulting company developed the Patient database system for the hospital ten years ago. TheBilling and Financial database systems were updated to an off the shelf system bought five yearsago. Royal Hospital would like to replace its three database systems (Patient, Billing and Financial)with one integrated system. It is planned that the integrated system will perform the same tasks as thecurrent systems and incorporate new features; for example, it would like to be able to give all thedoctors their own Personal Digital Assistant (PDA), which displays details about patients and theirtreatments.

1. Based on the scenario:

(a) Create a Level 0 Data Flow Diagram for the Royal Hospital. (22 marks)

(b) Create a Level 1 Data Flow Diagram to represent the processes associated with the process,enter the room and procedure details for a patient. (17 marks)

2. The Royal Hospital is considering replacing the three existing database systems with oneintegrated system.

(a) Describe the twotypes of system development methodologies available to assist the systemanalyst to review and replace the existing database management systems with one system.

(8 marks)

(b) Describe the advantages of each system development methodology. (12 marks)

(c) Recommend and justify the changeover method that you would use to implement the newdatabase management system. (5 marks)

(d) List and describe fivedata gathering techniques that the analyst could use to find out moreinformation about the current system. (15 marks)

Task 7 Software Programmer Caf Au latte Payroll SystemProject: Applying Software Development Cycle,algorithmic & programming techniques to create a prototype digital solutionUnit: 4 Developing Software Solutions88 marks 10%


Task Outline

You have been commissioned by Caf Au Latte to further develop the cash register computerisedsystem you developed for them in 2012 to include a program with a graphical user interface (GUI) thatwould allow a payroll clerk to calculate an employees pay i.e. enter data, perform calculations andoutput information. The program needs to also provide a timecard facility to allow employees toclock-in and clock-out at the beginning and end of their shift to automate the storage and calculation

of the hours and dates each employee worked.

It is recommended that you gather specific details on what data is needed by a payroll clerk beforeusing any computer program to calculate pay. Compare a number of current industry standard payroll

applications and the associated computer systems needed to run them.

Once you have gathered this information, develop a plan that: outlines the pros and cons ofintegrating the payroll system into the existing Caf au Latte system and the modifications needed tothe existing system, and your recommendations as to the feasibility of integrating the new system intothe existing one. Include an outline of your recommendation for the best way to provide the new

system and a timeline for developing the new payroll system.

With the aid of your generalised model of a payroll system, document and use the Systems

Development Life Cycle (SDLC) to develop a computer program with a graphical user interface (GUI)that will:

Allow a payroll clerk to: add new employees, remove and edit existing employees enter data,calculate wages and output information.

Allow each employee a secure means of clocking-in and clocking-out at the end of each shift.

Data can be retrieved or stored in external files or databases.

Refer to Task 8 Appendix for details of how wages are currently calculated including, pay cycle, payrates, holiday and overtime rates, time cards (clocking in clocking out), tax rates and deductions.

Task 11 Systems Development - Perth Bus toursProject: System DevelopmentUnit: 3 & 4115 marks 10%

Task OutlineYou have been employed by Perth Bus Tours to review its current company procedures and makerecommendations for improvement. The project will require a multitude of skills and your expertise as

a Systems Analyst will be necessary to oversee this project.

Time required for task

Three weeks

Client InformationThe manager has provided the following description of the system:

A customer rings the bookings clerk and asks for prices for various tickets. The bookings clerk quotesthe price and the customer either accepts or rejects the quoted price. If accepted, the customer buysthe appropriate Explorer Pass, using their credit card. The credit card details and transaction amountare sent to the bank via EFTPOS and a transaction number is generated by the bank. The bookingsclerk enters the details of the tour booking into the customer database. A receipt is sent to the customerfor their records, along with a numbered Explorer Pass Card that records the number of tours the cardis valid for. A copy of the receipt, which will be used to reconcile bank details at the end of the week, isplaced on a spike.

When the customer arrives in Perth and they ring to book their first tour to a particular tourist attraction,they are asked for their name and Explorer Pass Card number. The bookings clerk checks thecustomer database to make sure that the customer is a valid customer. If the Explorer Pass Card

number is valid, the relevant customer details are copied from the Customer Database into theBookings Database. The customer is asked for a contact phone number and their pickup details (hotelname and tour), which are entered into the bookings database. The bookings clerk tells the customerthe estimated pickup time and the bus number (e.g. Bus 1 = AQWA, Bus 2 = Fremantle) for their firsttour. The bookings clerk adjusts the number of tours the customer now has available to use.

At the end of the day, the manager uses the bookings database to allocate a bus and a driver to eachtour. The passenger lists are then emailed to the drivers and a copy is placed in the Daily Tours file.

On the day of the tour, the bus driver collects the customers from their hotel. The customer shows theirExplorer Pass Card to the driver who validates it and checks off the customers name on the passengerlist.

At the end of each trip the driver puts the checked passenger list into the Completed Tours tray.

Every Friday afternoon, the manager uses the customer database to generate a list of new customersand the amounts they have paid. This list and the copies of the receipts on the spike are used toreconcile the bank statement supplied by the bank. The reconciled statement and copies of receipts areplaced in the Bank Statement file.
