Chapter 1
INTRODUCTION

A complete understanding of software requirement is essential to the success of
software development effort. No matter how well design/well coded , a poorly
analyzed and specified program will disappoint the user and bring the grief to the user.
The requirement analysis task is a process of discovery, refinement, modeling
and specification. The software initially established by the system engineer and
refined during software project, planning is refined in detail. Models of the required
information and control flow, operational and data content are created. Alternative
solutions are analyzed and allocation to various software elements.
Requirements analysis, software-engineering task that bridge the gap between
system level software allocation and software design .Requirements analysis enables
to specify software function and performance indicates software’s interface with other
system elements and established design constraints that the software must meet.
Requirement analysis allows the software engineers to refine.
The software allocation and build models of processes, date and behavioural
domains that will be treated by software designer with a representation of information
and function that can be translated to data, architectural and procedural design.
Finally, the requirement specification the developer and customer with the means to
access quality once the software is built.

Chapter 4
Feasibility Study
It is the high level capsule version of the entire requirement analysis
process. The objective of feasibility study is to determine whether the proposed
system can be developed with available resources.
There are three steps to be followed for determining feasibility study of proposed
systems :
 Technical feasibility
 Operational feasibility
 Economical feasibility
4.1 Technical feasibility:
It is concerned with hardware and software feasibility. In this study, one has to
test whether the proposed system can be developed using existing technology or
not. As per client requirements the system to be developed should have speed
response because of fast exchange of information, reliability, security, scalability,
integration and availability. To meet these requirements we as a developer found JSP
specifications as a right choice because of its features platform independence and
reusability.

4.2 Operational feasibility:
Operational feasibility determines whether the proposed system satisfied
the user objectives and can be fitted in to current system operation. The system
“The Prepaid Rationing System” can be justified as operationally feasible based on
the following Operational feasibility determines if the proposed system satisfied the
user objectives and can be fitted in to current system operation. The system
“Prepaid Rationing System” can be justified as operationally feasible based on the
following:
 The methods of processing and presentation are completely acceptable by the
users because they meet all their requirements.
 The users have been involved during the preparation of requirement
analysis and design process.
 The system will certainly satisfy the user objectives and it will also
enhance their capability.
4.3 Economical feasibility:
This includes an evaluation of all incremental costs and benefits expected if
proposed system is implemented. Costs-benefit analysis which is to be done
during economical feasibility delineates costs for project development and
weighs them against system benefits. The system adds information of colleges
and companies for which colleges and companies pays as it provides their

information as well as company jobs. So developing this system is economically
feasible.
Chapter 5
System Design
DEFINITION:
Design is the first step in the development phase for any engineered
product/system. It may be defined as “The process of applying various techniques and
principles for the purpose of defining a device, a process/a system in sufficient detail
to permit its physical realization.
Once the software requirements have been analyzed and specified, the software
design involves three technical activities—Design, Code generation and testing, that
are required to build and verify the software.
The design activities are of main importance in this phase, because in this
activity decisions ultimately affecting the success of the software implementation and
its ease of maintenance are made. These decisions have the final bearing upon
reliability and maintainability of the system. Design is the only way to accurately
translate the customer’s requirements into finished software.

CHAPTER 7
System Testing
Tests are the individual tests specified in a test plan document.
Each test is typically described by
 An initial system state.

 A set of actions to be performed.
 The expected results of the test.
Test cases are planned in accordance to the test process and documented with detailed
test descriptions. These test cases use cases based on projected operational mission
scenarios. The testing process also includes stress / load testing for stability purpose
(i.e., at 95% CPU use, system stability is still guaranteed. The test process thoroughly
tests the interfaces and modules. Software testing includes a traceable white box
testing, black box testing and other test processes verifying implemented software
against design documentation and requirements specified.
7.1 Types of Testing:
 White Box Testing:
 Black Box Testing
7.1.1 White Box Testing
A level of white box test coverage is specified that is appropriate for the
software being tested. The white box and other testing uses automated tools to
instrument the software to measure test coverage. The program code is
examined for defects. It based on design and implementation structures. It deals
with internal logic and structure of the code.

7.1.2 Black Box Testing
A black box test of integration builds includes functional, interface, error
recovery, stress and out-of-bounds input testing. All black box software tests
are traced to control requirements. In addition to static requirements, a black
box of a fully integrated system against scenario sequences of events is
designed to model field operation. Performance testing for systems is integrated
as an integral part of the black box test process.
UNIT TESTING
Validations were made for each single module and each module was tested
independently. Maximum error detection was made at this stage. Proper flow of in
bound and out bound information was made.
INTEGRATED TESTING
Integration testing was carried out to check whether each module works
properly with the integrated module. Different inputs were given to the secondary
module from the primary, to check whether it works properly for each input which
comes from the higher level. Both Bottom-up and Top-down integration tests were
carried out.

ERROR HANDLING AND EXTREAM CONDITIONS:
The users of the system either ADMIN or CLIENT should enter all the
fields in the relevant forms. The entered fields should not violate the primary key
constraints. If the user either wants to update or delete a record, which is not in
database, it will display a message.
