WEB BASED EXAMINATION SYSTEM

1. INTRODUCTION

The project entitled WEB BASED EXAMINATION SYSTEM, in

BESSEL INFOTECH SOLUTION, Palakkad. This system is based on the college

examination. Here I am using PHP as frond end and MySQL 2005 as backend.

The software design is on the basis of the details provided by the company and

according to their requirements and is provided with the facilities to enter student

details, course details, subject details, staff details and option to provide reports.

The users will be satisfied with this software that will actually save the time

and strain needed for the works they are done manually and this is a fully menu driven

and interactive. So there is no need of giving special training for the operators. The

main objective of this system is to efficiently evaluate the candidate thoroughly

through a fully automated system that not only saves lot of time but also a gives fast

results. This system has mainly two modules. They are

Administrator

Student

In the existing system, the entire tasks are carried out manually. No automated

system has been implemented yet to reduce the risk associated with an examination. It

is very difficult and time consuming process.

Salient features of the system are:

Secure

Easy to use

No need of examiner

Reliable and accurate

2. SYSTEM ANALYSIS

System analysis is the primary phase of the software development. It refers to

a structured process for identifying and solving problems. Analysis is the central

impact of system development and I gathered data and designed a plan to the new

system. Analysis not only includes the process of analysis but also that of synthesis,

which is the process of putting parts together to form a new system.

2.1 Existing System

The whole process assigning test and evaluating their scores after the test, was

done manually till date. Processing the test paper i.e. checking and distributing

respective scores used to take time when the software was not installed.

Disadvantages of current system:

The current system is very time consuming.

No provision for the validation of data that is being entered i.e, if the user

enters some data that is not valid, there is no provision for rectifying the

errors.

To take exam of more candidates more invigilators are required but no need of

invigilator in case of on line exam.

Updating is very difficult.

Automatic report generation of student, staff was not available.

Results are not precise as calculation and evaluations are done manually.

The chances of paper leakage are more in current system as compared to

proposed system.

Result processing takes more time as it is done manually.

2.2 Proposed System

The di sadvantages of the existing system have been solved by using the new

system which helps to maintain the details of certificate, result details, staff details

etc. The proposed system is higher user friendly with PHP as front end and MySQL

3


4/28


2005 as its back end. The new system overcomes the problems encountered by

existing system.

Characteristics of the proposed system:

In comparison to the present system the proposed system will be less time

consuming and is more efficient.

Analysis will be very easy in proposed system as it is automated.

The proposed system is designed in such a way that many of the input

operations are done through well structured forms.

The forms are capable of validating and checking the integrity and correctness

of the input.

Result will be very precise and accurate and will be declared in very short

span of time because calculation and evaluations are done by the simulator

itself.

The proposed system is very secure as no chances of leakage of question paper

as it is dependent on the administrator only.

3. FEASIBILITY ANALYSIS

A feasibility study is made to see if the project on completion will serve the

purpose of the organization for the amount of work, effort and time that is spent on it.

Feasibility analysis is a test of system proposal regarding its workability, impact on

the organization, ability to meet the needs and effective use of resources. Thus when a

new project is proposed, it normally goes through a feasibility analysis before it is

approved for development. The list of various areas that were considered during thefeasibility analysis of this project such as

Technical Feasibility

Economical Feasibility

Operational Feasibility

Technical Feasibility

The system must be evaluated from the technical viewpoint first. The

assessment of this feasibility must be based on the outline design of the system

requirement in terms of input, output etc. Technical feasibility centers on the existing

manual system of the test management process and to what extent it can support the

system. According to feasibility analysis procedure the technical feasibility of the

system is analyzed and the technical requirements such as software facilities,

procedure, inputs are identified. It is also one of the important phases of the system

development activities.

Economical Feasibility

Economic feasibility is most frequently used for evaluation of the

effectiveness of the system. More commonly knows as cost/benefit analysis the

procedure is to determine the benefit and saving that are expected from a system and

compare them with costs, decision is made to design and implement of the system.

5


6/28


In the system, the organization is most satisfied by economic feasibility.

Because, if the organization implements this system, it need not require any additional

hardware resources as well as it will be saving lot of time.

Operational Feasibility

The proposed system will beneficial to the organization that satisfies the

objectives when developed and installed. The system offers greater levels of user

friendliness combined with greater processing speed. Therefore, the cost of

maintenance can be reduced. Since, processing speed is very high and the work is

reduced in the maintenance point of view that the project is operationally feasible.

4. SYSTEM SPECIFICATION

The system specification is the result of documenting the development phase

activities. It is completed at the conclusion of development phase. The system

specification is divided in to two parts; the first part is hardware specification, related

to the interaction of information system with its environment. The second part is

software specification that completely documents the computer program component

of the system.

5. SOFTWARE DESCRIPTION

Front-End: PHP

PHP stands for Hypertext Preprocessor and is a programming language which

is used for writing web applications - from ordinary web page to full blog or forum.

Being a server-side scripting language PHP runs on the web server, unlike the client-

side languages which run on the web browser, and gives you a lot of possibilities

other programming languages cannot.

Besides, the server-side code appears to be more protected than client-side one

as it stays on the web browser and the visitors are not able to view and edit it. When

the web page opens, PHP sends only the output to the visitors browser so you may be

sure no one will pilfer your script. However, PHP code that is kept within a server and

runs scripts is an open source which means that it is easily accessible. PHP is

available for free and is well supported being provided with source code so the users

can easily build and customize it according to their own preferences.

PHP language maintains a variety of useful features for the web, such as:

Options for working with HTML code, e.g. inserting PHP chunks in the

HTML page

Facilities for creating graphics

Function of addressing to databases, e.g. MySQL

Ease at handling web forms and setting cookies

The possibility to check email by POP3 or IMAP

PHP can be used also for command-line scripting and perfectly connects with

most web servers, platforms and operating systems as well as database systems of

relational types. It is made for quick creating of dynamic web pages and like other

server-side programming languages provide dynamic content from server to clients.

Using PHP you will develop your projects faster as it grants you with possibility of

8


9/28


separating HTML code from scripted elements. You can work with your project

coding separately from its building which will add to the effectiveness of the design.

Back-End: MySQL

MySQL is the world's most used relational database management system

(RDBMS) that runs as a server providing multi-user access to a number of databases.

It is named after developer Michael Widenius' daughter, My. The SQL phrase stands

for Structured Query Language.

The MySQL development project has made its source code available under the

terms of the GNU General Public License, as well as under a variety of proprietary

agreements. MySQL was owned and sponsored by a single for-profit firm, the

Swedish company MySQL AB, now owned by Oracle Corporation. Free-software-

open source projects that require a full-featured database management system often

use MySQL. For commercial use, several paid editions are available, and offer

additional functionality. Applications which use MySQL databases include: TYPO3,

Joomla, WordPress, phpBB, Drupal and other software built on the LAMP software

stack. MySQL is also used in many high-profile, large-scale World Wide Web

products, including Wikipedia, Google, Facebook, and Twitter.

Features of April 2009, MySQL offered MySQL 5.1 in two different variants:

the open source MySQL Community Server and the commercial Enterprise Server.

MySQL 5.5 is offered under the same licences. They have a common code base and

include the following features: Cross-platform support

Stored procedures

Triggers

Cursors

Updatable Views

Information schema

Strict mode

9


10/28


Limitations MySQL does not currently comply with the SQL standard for

some of the implemented functionality, including issues like silent ignore of standard

SQL Syntax, including silent ignore of check constraints, foreign key references, and

other features used to enforce business logic consistency. Triggers are currently

limited to one per action / timing, i.e. maximum one after insert and one before insert

on the same table. There are no triggers on views.

Future releases MySQL Server 6.0.11-alpha was announced May 22, 2009 as

the last release of the 6.0 line. Future MySQL Server development uses a New

Release Model. Features developed for 6.0 are being incorporated into future releases.

MySQL 5.6, a development milestone release, was announced at the MySQL users

conference 2011. New features include performance improvements to the query

optimizer, higher transactional throughput in InnoDB, new NoSQL-style,

improvements to partitioning for querying and managing very large tables,

improvements to replication and better performance monitoring by expanding the data

available through the PERFORMANCE_SCHEMA. In July further previews with a

BINLOG API, group commit, and InnoDB full text searching were released.

6. PROJECT DESCRIPTION

The project entitled WEB BASED EXAMINATION SYSTEM is software

that is used to conduct an online examination. I am doing this project for BESSEL

INFOTECH SOLUTION. Here I am using PHP as front end and MYSQL as back

end. The online exam has taking mainly in the following stages

Login

Exam Writing

Result

Mailing

* Login

There are mainly three login windows i.e., administrator login, staff login and

student login. The administrator login window can access only by the administrator

and the student login can access only by the students. This is more secure than other

login forms as in a normal login window there are multiple logins available so that

more than one student can access to write exam with their individual login.

* Exam Writing

This page is the most important page in this project. Whenever entering this

page it contains name of the student, course name, year and the student can select

subject for taking exam.

* Result

From this page select the year of examination then will display result i.e.,

Passed or Failed.

* Mailing

11


12/28


After writing the exam then the student is requesting for certificate. The

administrator reads the request and sends the certificate to the students.

The administrator can view the student report , staff report, result report on the

basis of selected year.

7. SYSTEM DESIGN

Design is defining a model of the new system and continues byconverting this model to a new system.The model is used to convert the model of the

proposed system into computer specification. Data models are converted to a data

base and processes and flows to user procedures and computer programs.Design

proposes the new system that meets these requirements. This new system may be built

by a fresh or by changing the existing system. The detailed design starts with three

activities, data base design, user design and program desin. Data base design uses

conceptual data model to produse a data base design. User procedure design uses

those parts of the DFD outside the automation boundary to design user procedures.

The detailed design of the system selected in the study phase is accomplished in this

phase. I achieved this by:

Module description

Input design

Output design

Data base design

Data flow diagram

7.1 Module Description

The project is divided in to two modules:

1.Administrator module

This is the first module of the project. This module mainly deals with the

details of student, course, staff, coursesubject etc.The question paper generation and

preparation are possible with in the staff login.

12


13/28


2.Student module

This is the second module of the project. This module deals with changing the

profile information, exam writing, viewing the resuts etc.

7.2 Input Design

Input design is the process of converting user designated input to a

computerized format. Data are entered through the keyboard and also the user can use

mouse for selecting the options. Error entered by the user can be controlled by the

input design.

All the input data are validated in the order and if any data is violated by any

condition the user is warned by message and asks to reenter the data. If the data is

satisfied all the conditions then its value is transferred to appropriate table in the

database. The various forms which we have designed in this phase are:

Login form

There are mainly two logins are available. They are administrator login

and student login. The staff registration form is inside the administrator.

Adminhome form

The administrator home page consists of the following links. They are

adding student details, course details, subject details, course with subject

details, view request and reports.

Student form

This page is used for entering student details and to add new students.

Staff details form

This page is used for storing staff details.

Change password form

This page is used for changing the password of staffs.

Course form

This page is used for entering course details and to add new courses.

Subject form

This page is used for entering subject details and to add new subjects.

Course Subject form

13


14/28


This page is used for entering course with subject details and to add new

details

Question Master form

This page is used for entering all questions corresponding to the course

subject and to add new questions.

Question Paper form

This page is used for generating various question paper to each students.

View Request form

This page is used for viewing the certificate request and set the status of

the request.

Student home

The student home page consists of the following links. They are change

profile detais, exam writing, view results and certificate request form.

Edit Profile form

This page is used for changing the profile details of the students.

.Exam Writing form

This page is the most important page. This page is used for writing the

exam.

View Result form

This form is used for viewing the result whenever selecting the year of

examination.

Certificate Request form

This form is used for requesting the certificate and also set the status of

the request.

7.3 Output Design

Designing computer output should proceed in an organized, well through out

manner, the right output must be developed while ensuring that each output element is

designed so that people will find the system easy to use effectively. A report contains

only predefined data obtained from multiple related records.

In the output design, it is determined how the information to be displayed for

immediate need and also the hard copy output. It is the most important direct source

14


15/28


of information. The objective of output design is to convey the information of all the

past activities and current status. The reports are the output design. They are

Student Report: This report contains the details of the students corresponding

to the selected year and course.

Examination Result Report: This report includes the details of examination

result corresponding to the selected year.

Staff Report: This report contains the details of the staffs corresponding to the

selected year.

7.4 Database Design

A database is an organized mechanism that has the capability of storing

information through which a user can retrieve stored information in an effective and

efficient manner.

7.5 Data Flow Diagram

The graphical description of systems data and how the processors perform the

data is known as data flow diagram. A graphical picture of the logical steps and

sequence involved in a procedure or a program is called flow chart.

Unlike detailed flow chart, Data Flow Diagram do not supply detailed

decription of the modules but graphically describe a systems data and how the data

interact with the system.

To construct a data flow diagram the following symbols are used.

Arrow

Circle

Open end box

An arrow identifies the dataflow in motion. It is a pipeline through which the

information is flwn like the rectangle in the flowchart. A circle stands for process that

converts data in to information. An open ended box represents a dataflow, data at rest

or temporary repository of data. A square defines a source or destination of system

data. A DFD can be represented by various levels.

System testing is a stage of implementation, which aims the assurance that the

system works accurately and efficiently before live operation commences. System

testing makes a logical assumption that if all parts of the system are correct, the goal

will be successfully achieved.

Objective of testing

Software testing is an important element of software quality assurance and

represents the ultimate review of specification, design and coding. There are several

rules that can serve as testing objectives. They are:

1. Testing is a process of executing a program with the intent of finding an error.

2. A good test case is one that has high probability of finding an undiscovered

error.

3. A successful test is one that uncovers an undiscovered error.

If testing where conducted successfully according to the objectives stated

above, it would uncover errors in the software. Also, testing demonstrates that

software function appears to the working according o the specification that

performance requirements appear to have been met.

Testing Methods

There are several methods of system testing. They are

Unit Testing

Integration Testing

User acceptance Testing

Output Testing

Validation Testing

8.1Unit Testing

Unit testing focuses on the smallest unit of software design of the module. The

modules of the system and database are tested separately. During programming stage

unit testing are carried out. Each module is tested separately and gets the expected

output from it. The unit testing is implemented by creating several users and allowing

them to use all the individual modules and the unit test is successfully completed. The

next step is integration testing.

23


24/28


8.2Integration Testing

Integration testing is a systematic technique for constructing tests to uncover

errors associated with the interface. In this project, all the modules are combined, and

the entire program is tested as a whole. Thus in the integration testing step, all the

errors are uncovered and corrected for the next testing steps.

The objective of the integration testing is to take the unit tested modules and to

build program structure. All the modules are combined and tested as a whole.

8.3 User acceptance Testing

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

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

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

required is done in regard to the following point:

Input screen design

Output screen design

Menu driven system

8.4 Output Testing

After performing the validation testing, 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 the specified format. The output generated or displayed by the system under

consideration is testing asking the users about the format required by them.

The output testing is used to test whether the system produces the required

output in the specified format.

8.5 Validation Testing

Validation testing is where requirements established as a part of software

requirement analysis is validated against the software that has been constructed.

During this test I made a final assurance that the software meets all functional and

performance requirements. The errors, which are uncovered during integration testing,

are corrected during this phase.

The system has gone through all the above steps of testing.

24


25/28


9. SYSTEM IMPLEMENTATION

Implementation is the stage in the project where the theoretical design is

turned in to a working system. If the implementation stage is not properly planned and

controlled it can cause chaos. Thus it can be considered to be the most crucial stage in

achieving a successful new system and giving the users confidence that the new

system will work and be effective and accurate. It is less creative than system design.

Implementation is primarily concerned with user training and documentation.

Depending on the nature of the system extensive user training may be required.

Conversion usually takes place about the same time the user is being trained or later.

Implementation simply means converting a new system design into operation. An

important aspect of the system analysts job is to make sure that the new system

design is implemented to establish standards.

The three types of implementation are:

Implementation of a new computer system to replace an existing one.

Implementation of a modified application to replace an existing one.

Implementation of a computer system to replace a manual.

Installation is a part of implementation which is concerned with the portion of

application from the developing site to the site of its working. The implementation

stage involves following tasks.

Careful planning.

Investigation of system and constraints.

Design of methods to achieve the changeover.

Training of the staff in the changeover phase.

Evaluation of the changeover method.

The method of implementation and the time scale to be adopted are found out

initially. Next the system is tested properly and the same time users are trained in the

new procedures.

25


26/28


10. CONCLUSION AND FUTURE ENHANCEMENT

Conclusion

The project was successfully completed within the time span allotted. Every

effort has been made to present the system in more user-friendly manner. All the

activities provide a feeling like an easy walk over to the user who is interfacing with

the system. All the disadvantages of the existing system have been overcome using

the present system ofWEB BASED EXAMINATION SYSTEM which has been

successfully implemented. A trial run of the system has been made and is giving good

results.

The system has been developed using the present scenario language PHP as its

front end tool and MYSQL 2005 as its back end. All the modules are tested separately

and put together to form the main system. Finally the system is tested with real data

and everything worked successfully. Thus the system has fulfilled the entire objective

identified. This system fully meets the objectives of the system for which it has been

developed. The system has reached a steady state where all bugs have been

eliminated.

The system has been developed in an attractive dialogs fashion and the entire

user interface is attractive and user friendly. So user with minimum knowledge about

the computers and the system can easily work with the system.

To conclude, I am thank all the persons who have helped me to complete this

project work successfully.

27/28


Future Enhancement

Changes can occur at anytime, anywhere. As the saying goes Change is the

only thing that certain. The needs can be vary day by day.

The application developed can be done with ease. The system has the

capability for easy integration with other system. Introducing the distributed database

concept can make further extension to this system. This helps in connecting various

departments together, comparing their performance and generating many valuable

reports.

The Web Based Examination System is built with the latest tools and the best

coding design in the market. The software is designed as maintenance free software.

A change in the operating system will affect the software and may need some

alterations to be done. Web Based Examination System is developed on a Windows

platform. The database used is MYSQL. In the coming years newer versions with

much advanced features will come up. The tables can be upgraded in this software

without much problem, without losing the data.

As far as the technology is concerned it tend to change soon, and the changes

are unpredictable. The process of re-engineering is always anticipated at any point of

time. So, certain enhancements can make this software a much better one.
