Introduction and Overview of the Project 2
In this portion we are going to deal with the swings, in which project has been made and Java
as the programming language, with a general overview about the project and how it works.
This project is developed to complete the needs of admin of data integration, data security.
Core Java
Introduction to Java & OOP’s concepts and their implementation in java
Java is an object oriented internet programming language.
Its main features are:-
11
 Open Source
 Platform Independence
 Security
A language is platform independent if it does not have any dependency on the operating
system.

Usually dependency on the O/S is created:-
At the time of development by invoking O/S library functions from the application,
At the time of compilation by following O/S specific format in compiled code, and
At the time of execution by using the O/S for launching the application.
That is, a Language is platform independent if:-
It is compiled in a platform mutual manner.
Language provides its own runtime environment for the execution of its application.
Language provides a comprehensive library for the application developers to develop all
types of application without using the O/S concern.
OOP’s
It is a programming model that simplifies software development and maintenance by
providing certain rules which are followed by the designer at the time of designing the
software and by the developers at the time of developing and maintaining the software.
The major advantage of this model is that we have habituated this model in our day to day
life.
Basic concepts of OOP’s
12
 Object
 Classification
 Generalization & Inheritance
 Polymorphism
 Data Encapsulation
Object
An object is a discrete (distinct/unique/different) entity that has well-defined attributes and
behavior. It can be a physical thing as well as an abstract thing.
Classification
Objects with common attributes, common behavior and having common relationship with
other objects are grouped into logical units called classes. This process is called
classification.
Classes are used to manage objects.
Generalization & Inheritance
Through generalization we pick up common attributes and behavior of class. In this way we
manage the class by using it.
Generalization is the way to achieve abstraction.

Polymorphism
It is a natural phenomenon which states that in real life one thing can exists in different
forms. E.g. - Water can be in three forms.
Data Encapsulation (To protect something)
It is a process by which we can encapsulate the data and this way we are protecting the data.
Oracle Database
A database management system (DBMS) is software that controls the storage, organization,
and retrieval of data.
A DBMS has the following elements:
Kernel code
This code manages memory and storage for the DBMS.
Repository of metadata
This repository is usually called a data dictionary.
Query language
This language enables applications to access the data.
13

Software and Hardware Requirements
The Requirements Specification is produced at the culmination of the analysis task. The
function and performance allocated to as part of system engineering are refined by
establishing a complete information description, a detailed functional description, a
representation of system behaviour, an indication of performance requirements and design
constraints, appropriate validation criteria, and other information pertinent to requirements.
The Introduction of the requirement specification states the goals and objectives of the,
describing it in the context of the computer-based system. Actually the introduction may be
nothing more than the software scope of the planning document. The information description
provides a detailed description of the problem that must solve. Information content, flow, and
structure are documented. Hardware, Software and human interfaces are described for
external system elements and internal software functions. For this project we need some
special type of environment for setup. This is as follows:
14

Objectives Of The System3
•Provide better understanding between admin.
• Provide a user friendly environment .
• To maintain and store students data.
• Provide excellent and easy access to admin.

18
System Analysis4
4.1 Introduction
System analysis is the process of studying the business processors and procedures,
generally referred to as business systems, to see how they can operate and whether
improvement is needed. I thoroughly studied the existing manual intranet system and felt
many shortcomings. I cover the following phases in this phase-
4.2 Investigation Phase
The investigation phase is also known as the fact-finding stage or the analysis of the
current system. The first step in software development life cycle is the preliminary
investigation to determine the feasibility of the system In this, I conducted a detailed
study with the purpose of wanting to fully understand the existing manual Intranet System
and to identify the basic information requirements.
4.3 Investigations
following methods to gather the information: -
1. Observation: - Necessary to see the way the system works first hand. And I observe
that there are registered people in the system. Some are approvers. An approver can also
be a requestor and they all handle equities using paper leave forms.
2 Document sampling: - These are all the documents that are used in the system.
Here I observe forms are used by orgaanizations in handling data which are necessary to
check all the data that enters and leaves the system.
3 Questionnaires: - These were conducted to get views of the other employees who
are currently employed in the system whether they are happy with present design of the
transport management systemor not.

4.4 Analysis of the investigation
19
Strengths of the Proposed System
(i). No complex equipment: - The GUI is used in the system which is very simple
and user-friendly and no special skills have to be mastered to be able to operate the
system.
(ii). Low cost: - There is little money spent in maintaining the proposed system which
is better than trails of paperwork.
4.5 Constraints and Limitation
The constraints and limitation within a system are the drawbacks that occur during the
implementation of the system. These limitations and constraints can crop up in almost
every system; the most important fact is to find a way to overcome these problems.
4.6 Design objectives
Software design is the first of three technical activities – design, code generation, and test
that are required to build and verify the software. Each activity transforms information in
manner that ultimately results in validated computer software.
The design task produces a data design, an architectural design, an interface design and
component design.
Some times it was quite difficult to enumerate that complexity of the problems and
solutions thereof since the variety of likely problems is so great and no solutions are
exactly similar however the following consideration I kept in mind during design phased-
Practicality: The proposed system has to be quite stable and can be operated by the
people with average intelligence.
Efficiency: I tried to involve accuracy, timeliness and comprehensiveness of the system
output.
Security: Proper authorization is done to take care of who is accessing the database and
proper security measures are taken.

Cost: It is desirable for the system with a minimum cost subject to the condition that it
must satisfy the entire requirement.
20
User Requirements
Company want a Bus management System for the Rajpal Transport company in which
they wants some facilities for admin.
Admin can add student- adding a student involves adding all the details related to that
student so that whenever needed can be used. He can also update student- this involves the
changes that can be made to a student’s detail, can change status of the student whether
he/she is using the bus facility or not. He can also modify the student details as and when
required. He can also add or remove bus on service according to the situation.He can also
hike or depreciate the fare of buses according to the circumstances.
So, overall Admin is having the full control over the entire system.He alone is responsible
for all kind of management activities.

22
Feasibility Study _______5
All projects are feasible – given unlimited resources and infinite time. But it is both
prudent and necessary to evaluate the feasibility of a project at the earliest possible time
and with the limited available resources.
Feasibility study includes considerations of all the possible ways to provide a solution to
the given problem. The proposed solution should satisfy all the user requirements and
should be flexible enough so that future changes can be easily done based on the future
upcoming requirements.
The feasibility study that was done for this project included the following considerations:-
A feasibility study is an evaluation of a proposal designed to determine the difficulty in
carrying out a designated task. Generally, a feasibility study precedes technical
development and project implementation. In other words, a feasibility study is an
evaluation or analysis of the potential impact of a proposed project.
Types of Feasibility Study
5.1 Technical Feasibility
This included the study of function, performance and constraints that may affect the ability
to achieve an acceptable system. For this feasibility the complete functionality to be
provided in the system and found that the following main tools will be required to build
the desired system. Technical feasibility centres on the existing computer system
(hardware or software etc.). The primary technical requirement includes the availability of
the software on the users system. Thus, through all the ends technical feasibility is met.
Most commonly known as cost benefit analysis, the procedure is determining the benefits
and savings that are expected from the candidate system and compare them with costs.
5.2 Economic Feasibility
This is a very important aspect to be considered while developing a project. We decide the
technology based on minimum possible cost factor.As the hardware was installed from the

very beginning, the cost on projection of hardware is low. As the project has been
developed on WAMP the software used is easily available.
5.2.1 Cost estimation of the project :
Software costs comprise a small percentage of overall computer based cost. There are a
number of factors, which are considered, that can affect the ultimate cost of the software
such as –human, technical, hardware and software availability etc.
Software Cost :
Oracle : 15000/-
JAVA : Free
Team cost : 25000/-
System Cost : 10,000/-
Total Cost : 50000/-
23
Manpower Cost :
Duration of Project:-
Time Duration
For study25 days
Designing 05 days
For development 25 days
Testing 05 days
Total time 60 days

5.3 Social feasibility
This is also taken in consideration as the society is moving towards the fastest technology
and is in need of the fastest communication channels. All information n can be provided to
an individual through the internet, which is becoming economical day by day.
5.4 Legal feasibility
A determination of any infringement, violation, or liability that could result from
development of the system.
Resource availability – Timings, required persons from different sections
Portability– Machine Independence across the platforms
The Software Requirements Specification is produced at the culmination of the analysis
task. Establishing a complete information description, a detailed functional and
behavioural description, an indication of performance requirements and data pertinent to
requirements refines the function and performance allocated to software.

Software Requirement Specification______6
The software requirement specification is produced at the culmination of the analysis
task.
6.1 Purpose
The purpose of this Software Requirement Specification (SRS) is tofully describe the
behaviour of the RT being developed. It also describes the non-functional requirements,
design constraints and other factors necessary to provide a complete and comprehensive
description of the requirements.
26
6.2 User Characteristics
The software requirements specification document enlists all necessary requirements that
are required for the project development. To derive the requirements we need to have
clear and thorough understanding of the products to be developed. This is prepared after
Detailed communications with the project team and customer.
RTconsist of module :
 Administrator
Role of an Administrator:
I. Can add student.
II. Update student- this involves the changes that can be made to astudent’s detail
III. Can change status of the student whether he/she is coming from same route or not..
IV. Can add bus and allocate to students
V. Can set status of the students if paid or due
VI. Can add school and allocate bus to it.
VII. Can generate enquiry report about the students
VIII. Payment slip is generated by Administrator for student’s using the bus facility.

27
6.3 General Constraints
facilities which are provided to market the service provided by the company.
6.4 Define the Goals:
The first step in the designing process IST of all defines the goals i.e. the goals of the
software. What the software is intended to do?
One wants everyone in the company or at least the most important people to be involved
in defining the project’s goal. Group consensuses make or break the project.
You also need to determine whether you have time to do a formal definition of goals or
whether an informal definition will suffice. A formal definition involves calling meeting
with the key players. You have to prepare an agenda and questions. It is fairly time-intensive
and much more demanding of your project-management skills. An informal
definition involves walking around with a notepad and talking to people one by one. You
write down their thoughts and ideas, ask for their options, and come back to them when
you need their approval.
Ask Questions
The basic set of questions should include:
What is the mission or purpose of the organization?
What are the short-and-long term goals of the project?
Who are the intended audiences?
6.5 Technical considerations:
Based on the answer of the above questions, especially regarding audience, one needs to
decide how to balance the newest feature against the system (server) compatibility and
the database.

System Data Flow Diagram
Data Flow Diagramming is a means of representing a system at any level of detail with a
graphic network of symbols showing data flows, data stores, data processes, and data
sources/destination.
The data flow diagram is analogous to a road map. It is a network model of all possibilities
with different detail shown on different hierarchical levels. This processes of representing
different details level is called “levelling” or “partitioning” by some data flow diagram
advocates.
Terms used in DFD
 Process
A process transforms data values. The lowest level processes are pure functions
without side effects. An entire data flow graphics high level process.
Graphical representation:
Graphical Representation:
 Data flows
A data flow connects the output of an object or process to input of another object
or process. It represents the intermediate data value within a computation. It is represented
by an arrow and labelled with a description of data, usually its name or type.
 Data store
A data store is a passive object with in a data flow diagram that stores data for later
access.

 External Entity
A rectangle represents an external entity such as a librarian ,a library member.

TESTING ________9
System testing includes the thorough testing of the product. System testing is actually a
series of different tests whose primary purpose is to fully exercise the computer based
system. The tests are recovery testing: this checks the recovery of the system when failure
occurs. This is to ensure that there are recovery procedures for error occurrences.
49
Objectives of testing:-
First of all objectives should be clear.
 Testing as a process of executing a program with the intent of finding errors.
 To perform testing, test cases are designed. A test case is a particular made up of
artificial situation upon which a program is exposed so as to find errors. So a good
test case is one that finds undiscovered errors.
 If testing is done properly, it uncovers errors and after fixing those errors we have
software that is being developed according to specifications.

50
9.1 TYPES OF TESTING:-
Testing is a major consideration in software development and maintenance. For many
organizations, more time is devoted to testing than any other phase of software
development. Use of well defined testing techniques and methods will minimize the
testing effort while maximizing the return on investment.
Various types of testing are available to verify the quality of the software developed. The
testing strategies that we followed are explained below:
 Testing will lead to find errors, it is vital for the success of the new system.
 The system is developed using the Agile model, so the testing is performed
In every part of iteration.
9.1.1 Unit Testing
Unit testing is a method of testing the correctness of a particular module of source code.
The idea is to write test cases for every non-trivial function or method in the module so
that each test case is separate from the others if possible. The developers mostly do this
type of testing. Unit testing focuses verification effort on the smallest unit of software
design-the software component module. Using the component level design description as a
guide, important control paths are tested to uncover error within the boundary of the
module. The relative complexity of tests and uncovered error is limited by the constrained
scope established for unit testing. The unit test is white-box oriented, and the step can be
conducted in parallel for multiple components. In this project, I have used unit testing to
test individual components.
Benefits:
Simplifies Integration eliminates uncertainty in the pieces themselves and can be used in
a bottom-up testing style approach.
Documents the code and provides a sort of "living document" for the class being tested.
Limitations:
It only tests the functionality of the units themselves. Therefore, it will not catch
integration errors, performance problems and any other system-wide issues.

Unit testing is only effective if it is used in conjunction with other software testing
activities.
9.1.2 Integration Testing
It is the phase of software testing in which individual software modules are combined and
tested as a group. It follows unit testing and precedes system testing. The purpose of
Integration testing is to verify functional, performance and reliability requirements placed
on major design items. It takes as its input modules that have been checked out by unit
testing, groups them in larger aggregates, applies tests defined in an Integration test plan to
those aggregates, and delivers as its output the integrated system ready for system testing.
Integration testing is a systematic way of constructing the program structure while at the
same time conducting tests to uncover errors associated with interfacing. The objective is
to take unit tested components and build a program structure that has been dictated by
design. I have used Bottom-Up Integration Testing in this project.
51
Benefits:
 It ensures that all the modules/parts of the system work as desired individually and
also as a whole.
 Output of one must not affect or alter the functioning of other.
Limitations:
 If modules/parts are tested as a single entity and not as a whole body later on, then
it may cause problems that may be difficult to solve.
9.2 VALIDATION CHECKS:
A common problem with computer system is that it is very easy to put incorrect data into
them. So the input data is validated to minimize errors and data entry. For certain data
specific code has been given and validations are done which enable the user to enter the
required data and correct them if they have entered wrong codes, e.g. you could mistype a
link name or a URL in a database resulting in reports being occurred in the wrong link
name. If you put incorrect data into the computer system then you will get incorrect
results out of it. Processing incorrect inputs will produce incorrect outputs. This lead to
the acronym: GIGO (Garbage in Garbage Out).

Sometimes incorrect data can actually cause a computer system to stop work temporarily.
This is a particular problem in batch processing systems when data may be processed
overnights. If incorrect data stops a batch processing systems for working then a whole
night processing time may be lost.
People who develop computer systems got to a lot of trouble to make it difficult for
incorrect data to be entered. The two main techniques used for this purpose are:
52
 VERIFICATION
 VALIDATION
These techniques are described in details below.
9.2.1 VERIFICATION:
A verification check ensures that data is correctly transferred into a computer from the
medium that it was originally stored on. Verification checks are usually used to check that
a data entry worker has correctly typed information written on a data collection form into
a computer.
9.2.2 VALIDATION:
A validation check is an automatic check made by computer to ensure that any data
entered into the computer is sensible. A validation check does not make sure that data has
been entered correctly. It only ensures that data is sensible. For this reason validation
checks are not usually as effective as verification checks. They can however be carried
out automatically by the computer and therefore require less work by the computer
operators making them cheaper to use.

System Maintenance 11
System maintenance is an extremely important activity in the life of a software product
that starts after the implementation phase. It is one form of change or rework. For proper
maintenance of this system, I am spending a good time on documentation so that I or
some other person can easily understand this system later when there is a need for
maintenance.

57
11.1 TYPES OF MAINTAINENCE
Software system maintenance covers a wide range of activities, including correcting
coding and design errors, updating documentation and test data and upgrading user
support. It is the process of changing the system to maintain its ability to survive. The
system design can adopt any of the under given system maintenance strategies.
11.1.1 Corrective Maintenance
The design software can be maintained by corrective maintenance that is concerned with
fixing reported errors in the software. Coding errors are relatively cheap to fix as
compared to design errors and requirement errors. The requirement errors are more
expensive, as redesigning of the entire system is to fix them.
11.1.2 Adaptive Maintenance
The design software can be maintained by adaptive maintenance if case there is a need to
change the system environment such as a different hardware platform or for using it with
different operating system.
11.1.3 Predictive Maintenance
The design system can be maintained by predictive maintenance if there is need to
implement new functional requirements. They are generated due to the changing
requirements of the software customers as their organization or business changes.
Maintenance of the system follows the following steps:-
 System Documentation
System documentation is a process that emphasizes on documentation the requirement,
design, plan, code implementation and testing of the system as whole.
In a product life cycle, there will be a number of documents like requirements
specification design, documents, user manuals, release documents etc. that will be
generated. The purpose of the system documentation process is to develop and maintain

the documentation that will be used to install and operate the product. This process also
ensures that the documentation developed is synchronized with latest product release.
Our product document typically consists of the following:
 Deliverable (file name size etc.): It includes the code after making changes in the
58
original code.
 Test Summary Report: It includes the result generated by executing the test
cases designed by us and the test cases given to us by the customer and
transporter. List of all the corresponding changes made in the existing code and
reason why the changes are necessary.
These documents not only ensures that the system is well designed and is fully complaint
with the needs of the user but also helps in further maintenance programmers of the
software system. A well documented system helps the maintenance of the software by
providing the maintenance programmers and insight.

Security Aspects 12
System security is a vital aspect when it comes to developing a system. The system
should ensure the facility of preventing unauthorized personnel from accessing the
information and the data within the system. The system should provide total protection
for each user’s information so that the integrity of the data is sustained.
The proposed system ensures the security and the integrity of data. This is done by
providing a password login system for each authorized user. At the starting of the
application, the user is asked for username and password and only the correct information
allows further navigation in the project. However, the System Administrator has access to
all kinds of information.
13.1 Access Rights
In the software security there are two levels of security. The 1st level of security, which is
provided by the FRONT END and 2nd level of security provided by the database which is
being used.
60
SOFTWARE INTERFACE
FRONT END: We have implemented SWING for all the Client side validations. It is
object based, event driven, platform independent. These are important parts of any Web
application to implement Client side Validations and the invalid data is not submitted.
The form is not submitted until user fills in correct data. It is extremely useful to restrict
mistakes by user.
BACK END: We have used Oracle/Access as the Back end. Oracle Server provides
efficient/effective solution for major database tech.
- Large database and space management.
- Many concurrent database users.
- High transaction processing requirement
- High Availability
- Industry accepted standards
- Manageable security
- Portability

FRONT END SECURITY: This security level is developed or designed by the s/w
developer or designer. She/he provides her/his s/w the security for the system, by
considering many factors regarding to the particular s/w.
In this software following are used to provide security.
LOGIN CHECKING:There is one login are provided in this software one for admin.
There is also provision to change the password in case password is known by other.

Conclusion
This project is a window-based application. The major part of the project is giving problem or
suggestion of user to admin about different features of different modules and provides
satisfaction to the users.
DEPENDENCIES
 It doesn’t matter how efficiently the application works, if the bandwidth is not
sufficient the transaction will take more time then expected.
 Oracle and Oracle JDBC-ODBC drivers for connectivity.
 Although this software is architecturally independent but following hardware
resources are required. For i.e. any PC or any other workstation with mouse support
and relevant software.
LIMITATIONS OF PROJECT
1) It is only for admin not for others.
2) Only able to handle offline communication through query.
3) No direct access to outsiders.
4) No direct customer relation to project.
FUTURE SCOPE OF PROJECT
 Make the database online to interact with customer directly.
 Providing the online payment of fees for students by the credit card and debit card users
more.
provide feedback facility for customers. .
