ABSTRACT Through this project we are planning to develop an intranet application for

CUSAT.The goal of our project is to automate the PG Evaluation process.

The present evaluation process is conducted through many processes. The

drawback of the present system is that transfer of result from each level is

entirely done manually and is hence time consuming. There is no proper

automated mechanism to manage these processes in an effective means. In the

present system ,it takes almost a year to publish the result.

We propose a system which is entirely computerized. The admin, chairman and

the camp are the users. They are provided with a user name and password to

login to their account. We provide an interface for the evaluators coming under

the camp to enter and view the marks during the evaluation. This provides a

secure means for the evaluators to enter the marks. Since the whole process is

computerized, it outputs an effective system with lesser chaos and improved

accuracy. This project can sustain as a long term project. The main

advantage on using this project are:

1. This project has great scope in the field of academics and results for

our university 2. The complexity in evaluation processes are reduced and hence

making it an easier job for the evaluators.

3. The delay in result publication is

Therefore the shortcomings of the present system can be overcome with the

help of our project.

PHP is used for front end and SQL server is used for backend database

storage.

CHAPTER 1 INTRODUCTION

The project entitled PG Evaluation System for cusat is an application that allows

evaluators to enter marks,view and print the report.

It is an intranet application which allows the registered users to

access the system, and at the same time it is secure and easy to use.

The advantages of this project are:

The project has great scope in the field of academics and results for our

university. It can sustain as a long term project.

The complexity in evaluation processes are reduced and hence making it an

easier job for the evaluators.

The delay in result publication is reduced. Therefore the shortcomings of the

present system can be overcome with the help of our project.

The project is divided into 4 modules.



1.Registration: Users are allowed to login according to the user name and

password. It allows providing the rights to delete and modify solely to the

administrator and allows only evaluators to enter the marks.

Sign in:Allowing already registered user(Administrator/Camp)

2. Mark entry: This module allows all evaluators coming under camp can enter mark

by specifying exam name,subject,and packet number.

3. Modify: Evaluator can modify the details such as mark,reg no,etc., before

submitting the details.

4. Print: In this module,after successfully entering the marks evaluator can print the

mark list by specifying the packet number and date.

By dividing the project into these modules the PG Evaluation System is made much

more user friendly.



CHAPTER 2 SYSTEM ANALYSIS

Here we go through the analysis of the existing system and proposed system. The

current system accomplishes the goal of evaluating answerbooks in a systematic

way.

2.1.EXISTING SYSTEM

2.1.1 EVALUATION PROCESS

The present evaluation process is conducted through many processes. All

examiners appointed to value the answerbooks related to the examination coming

under the board.There is a chairman for every board,appointed by the controller of the

examination.

The first evaluation will be done by the internal examiners appointed for the

purpose from teachers in the concerned departments.After first evaluation university will

arrange for the second valuation by external examiners.

Third phase is decision making step and is done by the chairman. Last set of evaluation

is done by the passing board,if the difference between the marks done by the two

evaluators is greater than 10% it is proceeded for 3rd evaluation .Else the average of two

are taken .Thus determines the final result of students .



2.1.2.DRAWBACKS OF THE EXISTING SYSTEM

The present evaluation process is conducted through many processes. The

drawback of the present system is that transfer of result from each level is entirely done

manually and is hence time consuming. There is no proper automated mechanism to

manage these processes in an effective means. In the present system, it takes almost a

year to publish the result.

We propose a system which is entirely computerized.The admin and the camp are the

users. The admin and the camp for evaluation are provided with a

user-name and password to login to their account.We provide an interface for the

evaluators coming under the camp to enter and view the marks during the evaluation.

This provides a secure means for the evaluators to enter the marks. Since the whole

process is computerized, it outputs an effective system with lesser chaos and improved

accuracy.

CHAPTER 3

DESIGN ANALYSIS

In this chapter we go through the analysis phase of the project using analysis tools such as Data Flow Diagram, Entity-Relationship diagrams .

3.1 INTRODUCTION

Designing requires a careful planning and thinking on the part of the system designer.

Designing website means to plan how the various parts of it are going to achieve the

desired goal. After the software requirements have been analyzed and specified, design

is the first of the three technical activities, Designing, Coding and Testing that are

required to build and verify the website.

3.2 ER DIAGRAM

ER Diagram is a graphical representation of entities and their relationships to each

other , typically used in computing in regard to the organization of data within

databases or information systems. An entity is a piece of data –an object or concept

about which data is stored. A relationship is how the data is shared between entities.

In the ER Digram shown in fig 3.1, the entities are camp,exam,evaluators. The entities

camp and evaluator has got a relationship with the entity exam. The

entity camp has got the attributes that is cmp_name,cmp_pwd,cmp_id.cmp_id is the key

attribute that is unique for every Camp. Camp has got a relationship consists with

Evaluator.Evaluator has a relationship selects with Exam.Evaluator has got the previlage

to add,delete nad modify marks with the exam.



fig 3.1.1 ER diagram



3.3 DATA FLOW DIAGRAM

Data Flow Diagram is a pictorial way of showing the flow of data into/within the system,

around the system and out of the system. It is a graphical representation of flow of data

within a system.Unlike, flowcharts, DFDs do not give detailed descriptions of modules

but graphically describe data and how the data interact with the system. The DFD enable

us to visualize how the system operates, its final output and the implementation of the

system as a whole including modification if any.The purpose of data flow diagram is to

provide a semantic bridge between users and sytem developers.

CHAPTER 5 IMPLEMENTATION

PG Evaluation system of cusat is basically for two types of users,camp and

administrator.These all users are allowed to access the system only after signing in with

a valid username and password.Thus a new user must sign up first to get a username

and set their password.

5.1 PHP

The PHP language was developed to help developer create dynamic and data driven

webpages.It was created in 1994 by Ramus Lerdorf as a simple macro language for

building small ,personal home pages,but quicklyoutgrew its original intended use and

became one of the most popular web developement tools on the market.PHP is used on

more than 1.5 million web sites around the world,and the number continues to grow.It is

now considered a tool of choice for all aspects of web developement,including creating

dynamic web content,business and

e-commerse sites,and web portals.

PHP interacts with one main external tool,the MYSQL database

management system,to access data stored in a database.MYSQL must be installed on

functional web server to interact with PHP,but this is relatively easy step in setting up

the PHP environment.

PHP is a server-side scripting language that you can embed into

HTML document.You can also embed HTML in PHP scripts.PHP scripts are parsed

and interrupted on the server side of a web applications.



5.1.1 PHP WEB PLANNING APPLICATION

This security logon component is the gateway to the whole system.This

component either grants or denies system access.A typically logon screen asks the user

for username and a password.The system then verifies that information against

information stored in the database.If the user passes this security check,the other parts of

the application become accessible.

5.1.2 What can PHP Do?

PHP can generate dynamic web pages

PHP can create,open,read,write,and close files on the server

PHP can collect from data

PHP can send and recieve cookies

PHP can add delete,modify data in your database

PHP can restrict users to access some pages on your website

PHP can encrypt data

5.1.3 Why PHP?

PHP runs on different platforms(Windows,Linux,Unix,Mac OS X,etc.) PHP is

compatible with almost all servsers used today(Apache,IIS,etc) PHP has

support for a wide range of databases.

PHP is free

PHP is easy to learnn and runs efficiently on the server side



5.2 SQL

SQL was one of the first commercial language for Edgar F Codd's relational

model,as described in his influential 1970 paper "A Relational Model of Data for Large

Shared Data Banks".Despite not adhering to the relational model as described by

Codd,it becames the most widely used database language.

SQL became a standard of the American National Standards Institute(ANSI) in

1986,and of the International Organization for Standards(ISO)in 1987.Since then,the

Standard has been enhanced several times with added features.But code is not

completely portable among different makers do not perfectly follow

the standard,they add extensions,and the standard is completely portable among

differevt dtabase systems,which can lead to vendor lock-in.The different makers do not

perfectly follow the standard,they add extensions,and the standard is sometimes

ambiguos.

5.2.1 What Can SQL do?

SQL can execute queries against a database

SQL can retrieve data from a database

SQL can insert records in a database SQL

can update records in a database SQL can

create new databases

SQL can create new tables in a database

SQL can create stored procedures in a database

SQL can create views in a database



SQL can set permissions on tables,procedures,and views

5.3 Registration

The admin and the camp are the the two users of PG Evaluation System .We provide

an interface for the evaluators coming under the camp to enter and view the marks during

the evaluation. This provides a secure means for the evaluators to enter the marks,the

camp and admin needs to sign in with a valid username and password.A new camp is

added by the admin by providing a valid username and password.

5.3.1 Sign in

Now a user can sign in with their new username and password.There are two types

of users so each categorized user will be redirected to different pages.

Camp : A camp user will be directed to camp's page where all evaluators coming

under camp can enter the mark,and also they can view and print the report.

Administrator : An administrator manages the entire system.He can add the new

camp,list of exams,subjects and courses.

5.4 Mark entry

All evaluators coming under camp can enter mark by specifying exam

name,subject and packet number.By entering first register number a field is

created and evaluator can enter mark in that field.Pressing add row will automatically

create fields such as reg no and mark to enter the details.



5.5 Modify

The user i.e Evaluator can modify the details such as mark,reg no etc before

submitting the details.

5.6 Print

After succsessfully entering marks evaluator can print the marklist by specifying the

packet number and the date.



CHAPTER 6 SYSTEM TESTING

Testing is all about to check the bugs in the software-development- process. Usually

what we do is with the help of some data, we check whether each and every phase of

the software is working as per the requirement. Suppose the range of inputs is [a, b] ∪

[c, d].Then usually the values that we select for testing are boundary values tht is

{a,b,c,d}

or any value x such that x>b or x<c. If the system is giving the satisfactory result then it

is passed through testing phase. Thus the aim of testing is to uncover requirements,

design or coding errors in the programs.

System is an expensive but critical process that can take as much as fifty percent of the

budget for program development. Consequential,

different levels of testing are employed. In fact a successful test is one that finds an

error.

Criteria deals with turnaround time back up, file protection and human factor. A test for

user acceptance should be carried out. The package developed was taken through

different levels of testing and required modifications were made.

6.1 TYPES OF TESTING System testing is the stage of implementation, which is aimed at ensuring that the

system works accurately and efficiently before live operation commences. Testing is vital

to success of system. System testing makes a logical assumption that if all the parts of

system are correct, the goal will be successfully achieved. The candidate system is

subject to a variety of tests.

A series of tests are performed for the proposed system before the system is ready

for user acceptance testing.The testing steps are



1. UNIT TESTING 2. INTEGRATION SYSTEM 3. VALIDATION TESTING 4..OUTPUT ESTING 5. USER ACCEPTANCE TESTING

6.1.1 UNIT TESTING Unit testing focuses verification efforts on the smallest unit of software design, the

module.. In unit testing each and every modules of our public website and staff website

are tested and verified. After that it is passed for integration testing.

6.1.2 INTEGRATION TESTING Data can be lost across an interface, one module can have an adverse effect on others,

and sub functions when combined may not produce the desired major functions.

Integration testing is a systematic testing for constructing the program structure. After

the successful unit testing, the modules which are error free are combined together for

the integrated system.

6.1.3 VALIDATION TESTING Validation testing runs the system in a simulated environment using simulated data.

This simulated testing is sometimes called alpha testing.

This simulated test is primarily looking for errors and monitions regarding

end user and decisions design specification that were specified in the earlier

phases but not fulfilled during construction. In alpha testing each and every module

is cross tested by different group members.

Validation refers to the process of using software in alive environment in order to find

errors. The feedback from validation phase

generally produces changes in software to deal with errors and failures that are

uncovered .Then a set of user sites is selected that puts the system in to use on



6.1.4 OUTPUT TESTING

After performing the validation, the next step is output testing of the proposed

system, since no system could be useful if it does not produce

the required output in specified format. Asking the users about the format required by

them tests the output generated or displayed by the system under consideration.

Hence the output format is considered in two ways-one is on screen and another in

printed format.

6.1.5 USER ACCEPTANCE TESTING

User acceptance of a system is the key factor for success of any system. The system under

consideration is tested for the user acceptance by constantly keeping in touch with the

prospective system users at the time of developing and making changes whenever

required. This is done in regard to the following point:

1.INPUT SCREEN DESIGN

2. OUTPUT SCREEN DESIGN

3. ONLINE MESSAGE TO GUIDE THE USER

4. FORMATS OF REPORTS AND OTHER OUTPUTS

6.2 TEST PROCEDURES FOLLOWED

We loaded the database of the project with the actual values for exam data and dummy

values of the mark data. The mark entry module of student is verified. If at the time of

filling any of the mandatory fields is not entered a pop up error message is displayed.

For testing the report generation,exam name,subject,packet numberand date are

entered. Depending upon the supplied data a report is generated.



CHAPTER 7 CONCLUSION

The proposed system has substantially replaced the existing manual pg

evaluation system.

We provided an interface for all evaluators coming under camp to enter or view marks

during evaluation.

The following procedures are implemented successfully:

Admin and Camp login

Entering register number and marks

Printing the mark report

The system is tested successfully and is found to have an effective planning of the

functions or process with a high degree of accuracy. The entire system is user friendly

and interactive. This system is developed to satisfy the needs of the office staff,and

evaluators. The proffered system is eminently efficient.

APPENDIX A:

To install apache, open terminal and type in these commands:

sudo aptget update sudo aptget install apache2

To install MySQL, open terminal and type in these commands:

sudo aptget install mysqlserver libapache2modauthmysql php5mysql

Once you have installed MySQL, we should activate it with this command:

sudo mysql_install_db

Finish up by running the MySQL set up script:

sudo /usr/bin/mysql_secure_installation

The prompt will ask you for your current root password.

Type it in.

Enter current password for root (enter for none): OK, successfully used password,

moving on...

Then the prompt will ask you if you want to change the root password. Go

ahead and choose N and move on to the next steps.

It’s easiest just to say Yes to all the options. At the end, MySQL will reload and

implement the new changes. To install PHP, open terminal and type in this command.

sudo aptget install php5 libapache2modphp5 php5mcrypt



After you answer yes to the prompt twice, PHP will install itself.

To see php on your server

To set this up, first create a new file:

sudo nano /var/www/info.php

Add in the following line: <?php phpinfo(); ?>

Then Save and Exit.

Restart apache so that all of the changes take effect:

sudo service apache2 restart

Mysql DB connection in PHP.

<?php

//Creating connection to DB

$connection = mysql_connect("localhost","$dbusername","$dbpassword");



if(!$connection)

{

die("Database connection failed: ".mysql_error());

}

//Selecting DB

$db_select = mysql_select_db("$dbname",$connection);

if(!$db_select)

{

die("Database selection failed: ".mysql_error());

}

//Mysql Query

$result = mysql_query(" query statement ");

if(!$result)

{

die("Database query failed: ".mysql_error());

}
