EXISTING SYSTEM

INTRODUCTION

The project is based on ONLINE TEST. . This software firm deals in developing software

for its clients. This a Notepad, using Java, Swing and AWT.

In modern civilization has become so complicated and sophisticated that to survive one has to

be competitive. This compiles the people to be acquainted with all type of happening in the

society; mankind is surrounded with a vast amount of data available. Modern business

management system has also rendered in a fashion so that it can be utilized with minimum

possible time. Paper files require a high amount of storage space and storage creates several

other problems like fire risk, spoilage and deterioration by way of aging humidity etc.

Computerization of documents and the files has solved this problem to create extent. Not only

this, but it has to be high amount of relaxation to human mind, as everything can be automated.

Now the documents can in a number of ways, styles and number of documents can be created

as and when required without making any mistakes.

Result


12/62

The institute currently operates under a manual system of conducting exams of students. The

primary function of the staff is to file and retrieve the information regarding the students, tests

and tests type, performance reports of every student in different subjects, and to maintain batch

records.

There are the five major areas in which the manual system affects costs:

Slow retrieval time results

The system is labor and space intensive

The manual system produces a risk of missing files

There is a lack of confidently.

No back up exists to support disaster recover.

The volume of paper is one of the things that stand in the way of increasing productivity in

institute.

Document retrieval Costs

Because batches are rarely cross referenced, the staff might have to look under several headings

to locate pertinent data. Even if the staff is conscientious about filling methods, locating

documents is still a labor and cost intensive operation.

Value of missing information

Combined with the typical lost document statics reviewed above, one could estimate the

industry average cost of not having the documents information when needed. But to obtain

first hand actual data for as software organization. This company decided to measure that actual

dollar value of lost information. Over a two week period, the file staff filled out a form for each

request to retrieve a document from the storage rooms. The data collected documented the total

number of filed requested and the results of each request.

Maintaining Registers is Costly


13/62

Traditionally, documents have been stored in batches and then filed in the cabinets and boxes.

A numerical system is then assigned. Specially a batch number assigned to organize the files.

Operative notes are classified alphabetically.

Listed below are the cost elements in our paper based filling system:

Labor: Creating new files, labeling, applying batch header sheets to file into the system,

collating and entering information into a batch log book.

Supplies: File folders, dividers, folder labels, batch header sheets, requisitions slips, file logs

and filling boxes.

Equipment: File cabinets and shelving units

FEASIBILITY STUDY1.ECONOMIC FEASIBILITY

Economic analysis 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, decisions is made to

design and implement the system.This part of feasibility study gives the top management the

economic justification for the new system. This is an important input to the management the

management, because very often the top management does not like to get confounded by thevarious technicalities that bound to be associated with a project of this kind. A simple

economic analysis that gives the actual comparison of costs and benefits is much more

meaningful in such cases.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.

2. TECHNICAL FEASIBILITY

Technical feasibility centers on the existing manual system of the test management process andto 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.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.


14/62

3. BEHAVIOURAL FEASIBILITY

People are inherently resistant to change and computer has been known to

facilitate changes. An estimate should be made of how strong the user is

likely to move towards the development of computerized system. These arevarious levels of users in order to ensure proper authentication and authorization and security

of sensitive data of the organization.

Software Requirement Analysis

This is also known as feasibility study. In this phase, the development team visits the customer

and studies their system. They investigate the need for possible software automation in the

given system. By the end of the feasibility study, the team furnishes a document that holds the

different specific recommendations for the candidate system. It also includes the personnel

assignments, costs, project schedule, and target dates. The requirements gathering process is

intensified and focused specially on software. To understand the nature of the program(s) to be

built, the system engineer ("analyst") must understand the information domain for the software,

as well as required function, behavior, performance and interfacing. The essential purpose of

this phase is to find the need and to define the problem that needs to be solved.

It saves time as it allows number of students to give the exam at a

time and displays the results as the test gets over, so no need to

wait for the result. It is automatically generated by the server.

Administrator has a privilege to create, modify and delete the test

papers and its particular questions.

User can register, login and give the test with his specific id, and

can see the results as well.


16/62

Document Conventions

The following are the list of conventions and acronyms used in this

document and the project as well:

Administrator: A login id representing a user with user administration

privileges to the software

User: A general login id assigned to users

Client: Intended users for the software

Examiner: Checks the test n gives result

Scope

Scope of this project is very broad in terms of other manually taking exams.

Few of them are:-

This can be used in educational institutions as well as in corporate

world. Can be used anywhere any time as it is a web based application(user

Location doesnt matter). No restriction that examiner has to be present when the candidate

takes the test.

The proposed LanguageSkill Exam System is an on-line Exam System.

The online test created for taking online test has following stages

Login

Test

Result

Login:-

There is a quality login window because this is more secure than other

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

so that more than one person can access to test with there individual login.

But in this project there is only one login id i.e. administrator id and

password by which a person enter the site. Hence it is more secure and

reliable than previously used on-line test simulators.


17/62

TEST:

Test page is the most creative and important page in this project. It

consists of 2 modules namely:

Subject selection

Utilities

Subject selection:-

From the given choices the candidate can select his

field (like C, C++ and JAVA, Eng etc) for taking on with the test.

Utilities:-

It includes:-

Skip and come back to the question afterwards if needed.

Gives the list of attempted and unattempted questions and can go to any question

directly and can either attempt or change the answer of the already attempted question.

version. The only requirement to use this online product would be the internet connection.

Design and Implementation Constraints


19/62

The whole implementation is done in two modules. The first one is

Administrator and the second is Examinee.

Module I:-

This first module tracks the path of Administrator. In this module it shows how the admin canlog into the system with a valid password and can add new valid user to the database. His name

and examid is saved in the database .Also he can manipulate the database and add new question

in the database from the webpage itself. It also shows how many questions

are in database.

Module II:-

This second module track the path for the examinee .The examinee can log into the system with

a valid ID issued by the admin. After successfully login into the system the examinee moves tothe instruction web page where he will get instruction about the examination process. Then

after clicking the start button the exam starts and timer also starts .In this manner examinee can

take up the test and clicking the submit button , he will get the result of

that section immediately. At the end system displays the initial web page.

Assumptions and Dependencies

Full working of OES is dependent on the availability of Internet connection and the software.

Assumptions:

In general it has been assumed that the user has complete knowledge of the

system that means user is not a nave user. Any data entered by him/her will

be valid. To make the software as user friendly as possible but at the same

time keeping in minds user requirements.

Server OS should be Windows NT/2000/XP.

Client PC should be Windows 9X/NT/WorkStation or Windows 2000

with latest service pack.

Dependencies:

It depends that the one should follow the international standards for the

generating the User ID & should fill the related information in the proper

format.


20/62

Database Storage

Description and Priority

Proposed Database is intended to store, retrieve, update, and manipulate information related to

university which include

Profile of both users

Student details

My account

Test results

Stimulus / Response Sequences

Responses for Administrator:The administrator can Login and Logout. When the

Administrator Logs into the Online Exam system. The system will check for validity of login

.If the Login and password are valid, the response to this action is the administrator will

be able to modify, view, add, deleting and all other functions that can be performed on the

database.

Examination:

First of all the user/examinee gets a valid identification number (same as the roll no for a

normal examination).The user can log on with this identification no. and can take up the

examination. After logging in the user can see various options and can choose the option from

the menu.

Functional Requirements

This section gives the list of Functional and non functional requirements which are applicable

to the Online Exam System. Functional requirements are nothing but the services provided by

the system to its end users. There are three sub modules in this phase.

Candidate module.

Examiner module.

Administrator module.

The functionality of each module is as follows.


21/62

Candidate module: The candidate will logon to the software and take his examination. He

can also check his previous examinations marks and his details. The candidate will get result

immediately after the completion of the examination.

Examiner module: The database is prepared & loaded into the software. Selection for

examination can be done language wise by the examiner. The results will be displayed

immediately after completion of the examination.

Administrator module: The administrator collects all the results after successful

completion of the examination and sends to the head quarters as and when required.

SYSTEM DEVELOPMENT LIFE CYCLE MODEL (SDLC

MODEL)

This is also known as Classic Life Cycle Model (or) Linear Sequential Model (or) Waterfall

Method. This has the following activities.

1. System/Information Engineering and Modeling

2. Software Requirements Analysis

3. Systems Analysis and Design

4. Code Generation

5. Testing

6. Maintenance

System/Information Engineering and Modeling

As software is always of a large system (or business), work begins by establishing requirements

for all system elements and then allocating some subset of these requirements to software. This

system view is essential when software must interface with other elements such as hardware,

people and other resources. System is the basic and very critical requirement for the existence

of software in any entity. So if the system is not in place, the system should be engineered andput in place. In some cases, to extract the maximum output, the system should be re-engineered

and spruced up. Once the ideal system is engineered or tuned, the development team studies the

software requirement for the system.


25/62

Software Requirement Analysis

This is also known as feasibility study. In this phase, the development team visits the customer

and studies their system. They investigate the need for possible software automation in the

given system. By the end of the feasibility study, the team furnishes a document that holds the

different specific recommendations for the candidate system. It also includes the personnel

assignments, costs, project schedule, and target dates. The requirements gathering process is

intensified and focused specially on software. To understand the nature of the program(s) to be

built, the system engineer ("analyst") must understand the information domain for the software,

as well as required function, behavior, performance and interfacing. The essential purpose ofthis phase is to find the need and to define the problem that needs to be solved.

System Analysis and Design

In this phase, the software development process, the software's overall structure and its nuances

are defined. In terms of the client/server technology, the number of tiers needed for the package

architecture, the database design, the data structure design etc are all defined in this phase. A

software development model is created. Analysis and Design are very crucial in the whole

development cycle. Any glitch in the design phase could be very expensive to solve in the later

stage of the software development. Much care is taken during this phase. The logical system of

the product is developed in this phase.

Code generation

The design must be translated into a machine-readable form. The code generation step performsthis task. If the design is performed in a detailed manner, code generation can be accomplished

without much complication. Programming tools like Compilers, Interpreters, and Debuggers

are used to generate the code. Different high level programming languages like C, C++, Pascal,

and Java are used for coding. With respect to the type of application, the right programming

language is chosen.


26/62

Testing

Once the code is generated, the software program testing begins. Different testing

methodologies are available to unravel the bugs that were committed during the previous

phases. Different testing tools and methodologies are already available. Some companies build

their own testing tools that are tailor made for their own development operations.

Maintenance

Software will definitely undergo change once it is delivered to the customer. There are many

reasons for the change. Change could happen because of some unexpected input values into the

system. In addition, the changes in the system could directly affect the software operations. The

software should be developed to accommodate changes that could happen during the post

implementation period.

System Design

Introduction: -

The objective of the system design is to deliver the requirements as specified in the

feasibility report. System design involves first logical design (logical design) and then

physical construction (detailed design) of the system. The logical design describes the

structure and characteristics of features, such as the outputs, inputs, files, databases, and

procedures. The physical construction produces actual program software, files, and a

working system.

System design goes through two phases of development: -

Logical Design

Physical Design

Logical Design:-

We know that a data flow diagram shows the logical flow of a system and defines the

boundaries of the system. Logical design specifies the user need at a level of details that

virtually determine the information flow into and out of the system and the required data

resources. Logical design describes the inputs, outputs, database and procedures .All in a

format that meets the users requirements.

Physical Design:-

It provides the working system by defining the design specification that tells programmers

exactly what that candidate system must do. In short it can state that physical design is the

implementation of the logical design.

Physical system design consists of the following-

Design the physical system

Specify input, output media

Design the database and specify backup procedures.

Design physical information flow through the system and a physical design walkthrough.

TECHNOLOGY USED:

JAVAJava Technology is both a programming language and a platform.

Java: The Programming Language

The Java programming language is a high level language that can be characterized by all of the

following buzzwords:

Simple

Object oriented

Distributed

Interpreted

Robust

Secure

Architecture neutral

Portable

High performance

Multithreaded

With most programming languages, you either compile or interpret a program so that you can

run it on your computer. The Java programming language is unusual in that a program is both

compiled and interpreted. With the compiler, first you translate a program into an intermediate

language called Java byte codes the platform-independent codes interpreted by the

interpreter on the Java platform. The interpreter parses and runs each Java byte code instruction


32/62

on the computer. Compilation happens just once; interpretation occurs each time the program is

executed. The following figure illustrates how this works.

The Java platform has two components:

The Java Virtual Machine (Java VM)

The Java Application Programming Interface (Java API)

Java Virtual Machine is standardized hypothetical computer, which is emulated inside our

computer by a program. It is base of Java platform and is ported onto various hardware-

based platforms.

The Java API is a large collection of ready-made software components that provide many

useful capabilities, such as graphical user interface (GUI) widgets. The Java API is grouped

into libraries of related classes and interfaces; these libraries are known as packages .

The following figure depicts a program that's running on the Java platform. As the figure

shows, the Java API and the virtual machine insulate the program from the hardware.

TESTING


33/62

FUNCTIONAL TESTING : - Functional testing is a type of black box testing that

bases its test cases on the specifications of the software component under test. Functions are

tested by feeding them input and examining the output, and internal structure program is rarely

structured.

Test case design focuses on a set technique for the cases that meet overall testing objectives. In

test case design phase, the engineer creates a series of test cases that are, intended to

demolish the software that has been built.

Any software product can be tested in one of two ways:

Knowing the specific function that a product has been designed to perform, test can

be conducted that demonstrate each function is fully operational, at the same timesearching for errors in each function. This approach is known as black box testing.

Knowing the internal working of a product, test can be conducted to ensure that

internal operation performs according to specification and all internal components

have been adequately exercised. This approach is know as white-box testing.

Black box testing is designed to uncover errors. They are used to demonstrate that software

function are operations; that input is properly accepted and output is correctly produced; andthat integrity of external information is maintained (e.g. data files.). A black box examines

some fundamental aspects of a system with little regard for the internal logical structure of the

software.

White box testing of software is predicated on close examination of procedural details.

Providing test cases that exercise specific set of conditions and loops test logical paths through

the software. The state of the program may be examined at various points to determine if the

expected or asserted status corresponds to the actual status.

STRUCTURAL TESTING: - Structural system testing is designed to verify that the

developed system and programs work. The objective is to ensure that the product designed is


34/62

structurally sound and will function correctly. It attempts to determine that the technology has

been used properly and that when all the component parts are assembled they function as a

cohesive unit.

The quality of a product or item can be achieved by ensuring that the product meets the

requirements by planning and conducting the following tests at various stages

Unit Tests at unit level, conducted by development team, to verify individual

standalone units.

Integration Tests after two or more product units are integrated conducted by

development team to test the interface between the integrated units.

Functional Test prior to the release to validation manager, designed and conducted

by the team independent of designers and coders, to ensure the functionality provided

against the customer requirement specifications.

Acceptance Tests prior to the release to validation manger, conducted by the

development team, if any supplied by the customer.

Validation Tests prior to customer, conducted by the validation team to validate the

product against the customer requirement specifications and the user documentation.

Regression Testing is the re-execution of some subsets of tests already been

conducted to ensure that changes are not propagated unintended side effects.

LEVEL OF TESTING: -


35/62

In order to uncover the errors present in different phases, we have the concept of levels of

testing. The basic levels of testing are:

Client Needs Acceptance Testing

Requirements System Testing

Design Integration Testing

Code Unit Testing

Fig. Level of Testing

Integration Testing

In this process of testing it is incremented approach to construction of program structure.

Modules are integrated moving downward beginning with main control module. Modules

subordinate structure to main control module is incorporated into structure. This form of testing

is performed of software in five steps: -

1. Main control module is used as test driver and stubs (modules) are

substituted for all components subordinate to main control.

2. Depending on integration selected subordinate stubs are replaced one at

a time.

3. Tests are conducted as each component is integrated.4. On completing each set of tests another stub is replaced.

5. It is also tested to ensure that new errors have not been introduced.

In well-factored program structure decision-making occurs at upper levels in hierarchy and

therefore encountered first. If major control problem do exist, early recognition is essential.

This is termed as top-down integration testing.

Bottom-up integration testing begins construction and testing with atomic modules as the

components are integrated from the bottom-up, processing required for componentssubordinate to a given level is always available and the need for stubs is eliminated.


36/62

Low-level components are combined into clusters that perform a specific software function.

A driver (a control program for testing) is written to coordinate test case input and output.

The cluster is tested.

Drivers are removed and clusters are combined moving upward in the program structure.

Each time a new module is added as part of integration testing, the software changes. New data

flow paths are established, new I/O can occur, and new control logic is invoked. These changes

cause problems with functions that previously worked flawlessly. In context of integration test

strategy

Successful tests result in discovery of errors and errors must be corrected. When software is

corrected some aspect of software configuration is changed.

Smoke testing

It is an integration testing that is commonly used when shrink wrapped software products are

being developed. It is designed as pacing mechanism for time critical projects, allowing us to

assess the project on frequent basis. This consists of steps: -

Software components are translated into code are integrated into a build. A build

includes all data files, libraries, reusable modules and engineered components.

A series of tests is designed to expose errors that will keep the build from properly

performing its function.

The build is integrated with other builds and the entire product is smoke tested daily.

Validation Testing prior to customer, conducted by the validation team to validate the product

against the customer requirement specifications and the user documentation.

TESTING THE PROJECT: -The best testing is to test each subsystem separately as we have done in our project. It is best to

test a system during the implementation stage in form of small sub steps rather then large


37/62

chunks. We have tested each module separately i.e. have completed unit testing first and

system testing was done after combining /linking all different Modules with different menus

and thorough testing was done. Once each lowest level unit has been tested, units are combined

with related units and retested in combination. These proceeds hierarchically bottom-up until

the entire system is tested as a whole. Hence we have used the Top Up approach for testing our

system.

IMPLEMENTATION


39/62

IMPLEMENTATION OF THE PROJECT: - The result indicated a considerable time

saving with the candidate system and comes out with fast and efficient development.

Implementation is the process of having system personnel check out and put new software into

use, trained user, installs the new application and constructs any strategies. Sometimes system

developers may choose to pilot the operation in only area of the firm, say in one department or

with only one or two persons. Sometimes they run old and new systems together to compare

the result.

The implementation phase is less creative than system design. Implementation means the

process of converting a new or a revised system design into an operational one. It is primarily

concerned with user training, site preparation, and file conversion. When the candidate system

is linked to terminals or remote sites, the telecommunication network and tests of the network

along with the system are also included under implementation.

Implementation is the realization of an application, or execution of a plan, idea, model,design,

specification, standard, algorithm, orpolicy.

In computer science, an implementation is a realization of a technical specification or algorithm

as aprogram, software component, or othercomputer system. Many implementations may exist

for a given specification or standard. For example, web browsers contain implementations of

World Wide Web Consortium-recommended specifications, and software development tools

contain implementations ofprogramming languages.

In the IT Industry, implementation refers to post-sales process of guiding a client from

purchase to use of the software or hardware that was purchased. This includes Requirements

Analysis, Scope Analysis, Customizations, Systems Integrations, User Policies, User Training

and Delivery. These steps are often overseen by a Project Manager using Project Management

Methodologies set forth in the Project Management Body of Knowledge. Software

Implementations involve several professionals that are relatively new to the knowledge based

economy such as Business Analysts,Technical Analysts, Solutions Architect, and Project

Managers..

40/62

adjusted to the changes created by the candidate system, evaluation and maintenance begin.

Like any system, there is an aging process that requires periodic maintenance of hardware and

software. If the new information is inconsistent with the design specifications, then changes

have to be made. Hardware also requires periodic maintenance to keep in tune with design

specifications. The importance of maintenance is to continue to bring the new system to

standards.

For the maintenance it has to be regularly checked whether all the devices are working

properly. If any of the devices on network is not working then that has to be checked and

amended in time.

PROJECT LEGACY

CURRENT STATUS OF THE PROJECT: - Till now, each modules, from index

page to thanks page are working so fine, and the result of each pages are meeting to the

requirements very well. The current status of the project is that the basics of discovering and

starting the projects are functional.

REMAINING AREAS OF CONCERN: -No remaining areas were left anymore.

All the modules have been accomplished with required controls.

TECHNICAL AND MANEGERIAL LESSONS LEARNT: - During the

development of system, I have learnt so many assets about tools, system language and many

more like:

1) I got to know how the classes(eg dataReader, dataset) fetches data and create table.

2)Moreover, files like Class file helps me to create numerous method.
