INTRODUCTION
In the existing system, most of the records are maintained on paper. It
becomes very inconvenient to modify the data. In the existing system, here is a
possibility that the same data in different registers may have different values
which means the entries of the same data do not match. This inconsistent state
does not supply the concrete information which poses a problem in the case
information related to particular search record. Our project is very useful. User is
no longer required to check his register in search of records, as now it can be
searched over the software by choosing some options. The user need not to
type in most of the information. He/she is just required to enter the desired
options. On the whole it liberates the user from keeping lengthy manual records.
In a nutshell, it abates the work load of an organization.
In today’s world, no one likes to perform calculations on calculator or
manually when computer is there. Every one wants his/her work to be done by
computer automatically and displaying the result for further manipulations.
A book shop uses a personal computer to maintain the inventory of books that
are being sold at the shop. The list includes details such as author, title, price,
publisher, stock position, etc. Whenever a customer wants a book, the
shopkeeper inputs the title and author of the book and the system replies
whether it is in the list or not. If it is not, an appropriate message s displayed. If
book is in the list, then the system displays the book details and asks for number
of copies. If the requested copies are available the, total cost of the books is
displayed; otherwise the message “Required copies not in stock” is displayed.

Existing System:
While Modifying a record, the person will have to first search the record
and then make changes of that particular record in every related register.
PROPOSED SYSTEM
The following documentation is a project the “Book Rental System”. It is a
detailed summary of all the drawbacks of the old system and how the new
proposed system overcomes these shortcomings. The new system takes into
account the various factors while designing a new system. It keeps into the
account the Economical bandwidth available for the new system. The foremost
thing that is taken care of is the Need and Requirements of the User.
DESCRIPTION
Before developing software we keep following things in mind that we can
develop powerful and quality software

REQUIREMENT ANALYSIS
This process is adopted when management of the system development,
Personnel decide that the particular system needs improvement. The system
development life cycle is the set of activities, carried out by the analyst,
designers and users to develop and implement a system. The systems that are
present in the nature follow common life cycle pattern. For example consider the
raining system. Initially the rain falls into the river, river flows into sea, the sea
water evaporates to form vapors, the vapors form clouds which again bring rain.
Similarly consider a man made system initially a system is analyzed, designed
and made operational by the efforts of system analysis. After successful
operation or a number of users, the system becomes less and less effective by
change in the environment. So these changes have to be incorporated in to the
system by minor modifications. So the general activities from the life cycle of the
system are given below:
Selection and identification of the system to be studied
Preliminary study
Defining the system
Design and development of the system

Implementation of the system
PROJECT TO BE DEVELOPED IS GOING TO ACHIEVE THE
FOLLOWING OBJECTIVES:
Helps in eliminating the individual maintenance of the record of storage of
books in any educational institute
Helps in reducing maintenance time by automatically shifting /. Storing
the information in relevant modules.
Helps in fast retrieval or instant availability of information required.
Provides flexibility to bring the required change in a record case
of
modification or deletion or seeking information of queries.
Helps in reducing manual power requirement to a single person.

SYSTEM ANALYSIS
System analysis is a process of gathering and interpreting facts,
diagnosing problems and the information to recommend improvements on the
system. It is a problem solving activity that requires intensive communication
between the system users and system developers. System analysis or study is
an important phase of any system development process. The system is studied
to the minutest detail and analyzed. The system analyst plays the role of the
interrogator and dwells deep into the working of the present system. The system
is viewed as a whole and the input to the system are identified. The outputs from
the organizations are traced to the various processes. System analysis is
concerned with becoming aware of the problem, identifying the relevant and
decisional variables, analyzing and synthesizing the various factors and
determining an optimal or at least a satisfactory solution or program of action.
A detailed study of the process must be made by various techniques like
interviews, questionnaires etc. The data collected by these sources must be
scrutinized to arrive to a conclusion. The conclusion is an understanding of how
the system functions. This system is called the existing system. Now the existing
system is subjected to close study and problem areas are identified. The
designer now functions as a problem solver and tries to sort out the difficulties
that the enterprise faces. The solutions are given as proposals. The proposal is
then weighed with the existing system analytically and the best one is selected.
The proposal is presented to the user for an endorsement by the user. The
proposal is reviewed on user request and suitable changes are made. This is
loop that ends as soon as the user is satisfied with proposal.
Preliminary study is the process of gathering and interpreting facts, using
the information for further studies on the system. Preliminary study is problem
solving activity that requires intensive communication between the system users
and system developers. It does various feasibility studies. In these studies a
rough figure of the system activities can be obtained, from which the decision
about the strategies to be followed for effective system study and analysis can
be taken.
11

FEASIBILITY STUDY
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 the time that
spend on it. Feasibility study lets the developer foresee the future of the project
and the usefulness. A feasibility study of a system proposal is according to its
workability, which is the impact on the organization, ability to meet their user
needs and effective use of resources. Thus when a new application is proposed
it normally goes through a feasibility study before it is approved for development.
The document provide the feasibility of the project that is being designed
and lists various areas that were considered very carefully during the feasibility
study of
this project
such
as Technical,
Economic
and
Operational
feasibilities. The following are its features:
A.
TECHNICAL FEASIBILITY
The system must be evaluated from the technical point of view
first. The assessment of this feasibility must be based on an outline
design of the system requirement in the terms of input, output, programs
and procedures. Having identified an outline system, the investigation
must go on to suggest the type of equipment, required method
developing the system, of running the system once it has been designed.
Technical issues raised during the investigation are:
Does the existing technology sufficient for the suggested
one?
Can the system expand if developed?
The project should be developed such that the necessary functions
and performance are achieved within the constraints. The project is
developed within latest technology. Through the technology may become
obsolete after some period of time, due to the fact that never version of
same software supports older versions, the system may still be used. So
there are minimal constraints involved with this project. The system has
been developed using Java the project is technically feasible for
development.
13
B.
ECONOMIC FEASIBILITY
The developing system must be justified by cost and benefit.
Criteria to ensure that effort is concentrated on project, which will give
best, return at the earliest. One of the factors, which affect the
development of a new system, is the cost it would require.
The following are some of the important financial questions asked
during preliminary investigation:
The costs conduct a full system investigation.
The cost of the hardware and software.
The benefits in the form of reduced costs or fewer costly
errors.
Since the system is developed as part of project work, there is no
manual cost to spend for the proposed system. Also all the resources are
already available, it give an indication of the system is economically
possible for development.
C.
BEHAVIORAL FEASIBILITY
This includes the following questions:
Is there sufficient support for the users?
Will the proposed system cause harm?
The project would be beneficial because it satisfies the objectives
when developed and installed. All behavioral aspects are considered
carefully and conclude that the project is behaviorally feasible.

ABOUT OPERATING SYSTEM
Windows XP is a line of operating systems developed by Microsoft for use
on general purpose computer systems, including home and business desktops,
notebook computers and media centers. The letters ‘XP’ stand for experience.
Windows XP is the successor to both Windows 2000 and Windows Me and is
first consumer oriented operating system produced by Microsoft to be built on
the Windows NT kernel and architecture.
The most common editions of operating systems are Windows XP home
edition, which is targeted at home users, and Windows XP professional, which
has additional features such as, support for Windows server domain and two
physical processors and is targeted at power users and business clients.
Windows XP Tablet PC edition is designed to run the ink-aware Tablet PC
platform. Two separate 64 bit versions of Windows XP were also released,
Windows XP 64 bit edition for IA-64(Itanium) processors and Windows XP
Professional x64 edition for x86-64 processors.

SOFTWARE DESCRIPTION
Microsoft Visual Basic.Net
Visual Basic .NET (VB.NET or VB .NET) is a version of Microsoft's Visual Basic
that was designed, as part of the company's .NET product group, to make Web
services applications easier to develop. According to Microsoft, VB .NET was
reengineered, rather than released as VB 6.0 with added features, to facilitate
making fundamental changes to the language. VB.NET is the first fully objectoriented programming (OOP) version of Visual Basic, and as such, supports
OOP concepts such as abstraction, inheritance, polymorphism, and aggregation.
In the Visual Basic NET design time environment, the first thing to concentrate
on is that strange, big square in the top left. That's called a form. It's actually the
pretty bit of your programme, the part that others will see when they launch your
masterpiece. Granted, it doesn't look too attractive at the moment, but you'll
soon discover ways to lick it into shape.
To run the form, try this:
From
the menu bar, click Debug
From
the drop down menu, click Start
Alternatively,
Your
press the F5 key on your keyboard
programme is launched
Congratulations! You have now created your very first programme. It should look
like this:
16
Click the Red X on the form to stop it from running. You will then be returned to
the software environment.
Things like buttons, textboxes, and labels are all things that you can add to your
Forms. They are know as Controls, and are kept in the Toolbox for ease of use.
The Toolbox can be found on the left of the screen. In the picture below, you can
see the toolbox icon next to Form1:
To display all the tools, move your mouse over the toolbox icon. You'll see the
following automatically appear:
There are seven categories of tools available.
The toolbox you'll be working with first is the
Common Controls toolbox. To see the tools,
click on the plus symbol next to Common
Controls. You'll see a long list of tools:
As you can see, there are an awful lot of tools to
choose from! For this first section, we'll only be
using the Button, the TextBox and the Label.
If you want to keep the toolbox displayed, click
the Pin icon next to the X. To close the toolbox,
simply move your mouse away.
In the next part, we'll see how to add a textbox to
the form.
17
How to Add a Control to your VB .NET Forms
Let's start by adding a textbox to our form. With the tools displayed, do the
following:
Locate the TextBox tool
Double click the icon
A textbox is added to your
form
The textbox gets added to the top left position of
your form. To move it down, hold your mouse
over the textbox and drag to a new position:
Notice the small squares around the textbox.
These are sizing handles. Move your mouse
over one of them. The mouse pointer turns into
an extended line with arrowheads. Hold your left
mouse button down and drag outwards. The
textbox is resized. Play around with the sizing
handles until you're happy with the size of your
textbox.
One thing you will notice is that you can't make
the size any higher, but you can make it wider. The reason why you can't make it
any higher is because the default action of a textbox is to have it contain only a
single line of text. If it's only going to contain one line of text, Microsoft reasoned,
there's no reason why you should be able to change its height. A textbox can
only be made higher if it's set to contain multiple lines of text. You'll see how to
do this soon.
Create
two
more
textboxes by double
clicking on the textbox
icon in the toolbar (Or
Right-click
on
the
selected textbox and
choose Copy. Then
Right-click on the Form
and choose Paste.)
Resize them to the
same size as your first
one
Line them up one
below the other with
space in between
Try to create something
that looks like the one below

Microsoft Access 2003.
Microsoft Access is the default database of Microsoft Visual Basic.
Microsoft Access 2003 provides many new features that make working with data
and designing a database even easier.
Microsoft Access Database is a
collection of data and objects related to particular topic or purpose. Microsoft
Access Database may contain tables; queries, forms, reports, macros modules
and shortcuts top data access pages.
Microsoft Access is a Relational Database Management System. Using
Access we can organize our data according to subject and can store information
about how different subject are related. In general MS-Access database can
have several small tables.
Microsoft Office Access, previously known as Microsoft Access, is a relational
database management system from Microsoft that combines the relational
Microsoft Jet Database Engine with a graphical user interface and software
development tools. It is a member of the 2007 Microsoft Office system.
Access can use data stored in Access/Jet, Microsoft SQL Server, Oracle,
or any ODBC-compliant data container (including MySQL and PostgreSQL).
Skilled software developers and data architects use it to develop application
software. Relatively unskilled programmers and non-programmer "power users"
can use it to build simple applications. It supports some object-oriented
techniques but falls short of being a fully object-oriented development tool.
Access was also the name of a communications program from Microsoft,
meant to compete with ProComm and other programs. This proved a failure and
was dropped. Years later Microsoft reused the name for its database software.
Access is used by small businesses, within departments of large
corporations, and by hobby programmers to create ad hoc customized desktop
systems for handling the creation and manipulation of data. Access
can
be
used as a database for basic web based applications hosted on Microsoft's
Internet Information Services and utilizing Microsoft Active Server Pages ASP.
Most typical web applications should use tools like ASP/Microsoft SQL Server or
the LAMP stack.
19
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. The data is the purpose of any database and must be
protected.
The database design is a two level process. In the first step, user
requirements are gathered together and a database is designed which will meet
these requirements as clearly as possible. This step is called Information Level
Design and it is taken independent of any individual DBMS.
In the second step, this Information level design is transferred into a design
for the specific DBMS that will be used to implement the system in question.
This step is called Physical Level Design, concerned with the characteristics of
the specific DBMS that will be used. A database design runs parallel with the
system design. The organization of the data in the database is aimed to achieve
the following two major objectives.
Data Integrity
Data independence
Normalization is the process of decomposing the attributes in an application,
which results in a set of tables with very simple structure. The purpose of
normalization is to make tables as simple as possible. Normalization is carried
out in this system for the following reasons.
To structure the data so that there is no repetition of data, this helps in
saving.
To permit simple retrieval of data in response to query and report request.
To simplify the maintenance of the data through updates, insertions,
deletions.
To reduce the need to restructure or reorganize data which new
application requirements arise.
20
RELATIONAL DATABASE MANAGEMENT SYSTEM (RDBMS):
A relational model represents the database as a collection of relations.
Each relation resembles a table of values or file of records. In formal relational
model terminology, a row is called a tuple, a column header is called an attribute
and the table is called a relation. A relational database consists of a collection of
tables, each of which is assigned a unique name. A row in a tale represents a
set of related values.
RELATIONS, DOMAINS & ATTRIBUTES:
A table is a relation. The rows in a table are called tuples. A tuple is an
ordered set of n elements. Columns are referred to as attributes.
Relationships have been set between every table in the database. This
ensures both Referential and Entity Relationship Integrity. A domain D is a
set of atomic values. A common method of specifying a domain is to
specify a data type from which the data values forming the domain are
drawn. It is also useful to specify a name for the domain to help in
interpreting its values. Every value in a relation is atomic, that is not
decomposable.
RELATIONSHIPS:
Table relationships are established using Key. The two main keys of
prime importance are Primary Key & Foreign Key. Entity Integrity and
Referential Integrity Relationships can be established with these keys.
Entity Integrity enforces that no Primary Key can have null values.
Referential Integrity enforces that no Primary Key can have null values.
Referential Integrity for each distinct Foreign Key value, there must exist
a matching Primary Key value in the same domain. Other key are Super
Key and Candidate Keys.
Relationships have been set between every table in the database. This
ensures both Referential and Entity Relationship Integrity.

SYSTEM IMPLEMENTATION
Implementation is the stage in the project where the theoretical design is
turned into a working system. The implementation phase constructs, installs and
operates the new system. The most crucial stage in achieving a new successful
system is that it will work efficiently and effectively.
There are several activities involved while implementing a new project they are
End user training
End user Education
Training on the application software
System Design
Parallel Run And To New System
Post implementation Review
End user Training:
The successful implementation of the new system will purely upon the
involvement of the officers working in that department. The officers will be
imparted the necessary training on the new technology.
End User Education:
The education of the end user start after the implementation and testing is
over. When the system is found to be more difficult to under stand and complex,
more effort is put to educate the end used to make them aware of the system,
giving them lectures about the new system and providing them necessary
documents and materials about how the system can do this.
Training of application software:
After providing the necessary basic training on the computer awareness,
the users will have to be trained upon the new system such as the screen flows
and screen design type of help on the screen, type of errors while entering the
data, the corresponding validation check at each entry and the way to correct the
data entered. It should then cover information needed by the specific user or
group to use the system.
Post Implementation View:
The department is planning a method to know the states of t he past
implementation process. For that regular meeting will be arranged by the
concerned officers about the implementation problem and success
TESTING
64
Testing is a process of executing a program with the interest of finding an
error. A good test is one that has high probability of finding the yet undiscovered
error. Testing should systematically uncover different classes of errors in a
minimum amount of time with a minimum amount of efforts. Two classes of
inputs are provided to test the process
A
software
configuration
that
includes
a
software
requirement
specification, a design specification and source code.
A software configuration that includes a test plan and procedure, any
testing tool and test cases and their expected results.
Testing is divided into several distinct operations:
1.
Unit Testing
Unit test comprises of a set tests performed by an individual
program prior to the integration of the unit into large system. A program
unit is usually the smallest free functioning part of the whole system.
Module unit testing should be as exhaustive as possible to ensure that
each representation handled by each module has been tested. All the
units that makeup the system must be tested independently to ensure
that they work as required.
During unit testing some errors were raised and all of them were
rectified and handled well. The result was quiet satisfactory and it worked
well.
2.
Integration Testing
Integration testing is a system technique for constructing the
program structure while at the same time conducting tests to uncover
errors associated with interfacing. The objective is to take unit tested
modules and build a program structure that has been dictated by design.
Bottom-up integration is the traditional strategy used to integrate the
components of a software system into functioning whole. Bottom-up
integration consists of unit test followed by testing of the entire system. A
sub-system consists of several modules that communicated with other
defined interface.
65
3.
Validation Testing
After validation testing, software is completely assembled as a
package, interfacing errors that have been uncovered and corrected and
the final series of software test; the validation test begins. Steps taken
during software design and testing can greatly improve the probability of
successful integration in the larger system. System testing is actually a
series of different tests whose primary purpose is to fully exercise the
compute –based system.
4.
Recovery Testing
It is a system that forces the software to fail in a variety of ways
and verifies that the recovery is properly performed.
5.
Security Testing
It attempts to verify that protection mechanisms built into a system
will in fact protect it from improper penetration. The system’s security
must of course be tested from in vulnerability form frontal attack.
6.
Stress Testing
Stress tools are designed to confront programs with abnormal
situations. Stress testing executes a system in a manner that demands
resources in abnormal quantity and volume.
7.
Black Box Testing
Black box testing is done to find out the following information as
shown in below:
Incorrect or missing functions.
Interface errors.
Errors or database access.
Performance error.
Termination error.
The mentioned testing is carried out successfully for this
application according to the user’s requirement specification.
8.
Test Data Output
After preparing test data, the system under study is tested using
the test data. While testing the system using test data, errors are again
uncovered and corrected by using above testing and corrections are also
noted for future use.
66
CONCLUSION & FUTURE ENHANCEMENT
The new realities of Digital information processing require that access is
provided in a widely distributed manner, and it is up to the user to locate what is
needed. The ability to call up all relevant information at the click of a mouse is a
researcher’s dream. In future we develop a Book-bank monitoring system project
aims at developing a software infrastructure that enables those who manage and
maintain such collections to make them publicly available. The entire
University/College/ department/ community stands to benefit greatly from an
online book-bank monitoring system. The system will enable the update,
retrieval, deletion, and generation of status reports according to the existing
demands.

INTRODUCTION
In the existing system, most of the records are maintained on paper. It
becomes very inconvenient to modify the data. In the existing system, here is a
possibility that the same data in different registers may have different values
which means the entries of the same data do not match. This inconsistent state
does not supply the concrete information which poses a problem in the case
information related to particular search record. Our project is very useful. User is
no longer required to check his register in search of records, as now it can be
searched over the software by choosing some options. The user need not to
type in most of the information. He/she is just required to enter the desired
options. On the whole it liberates the user from keeping lengthy manual records.
In a nutshell, it abates the work load of an organization.
In today’s world, no one likes to perform calculations on calculator or
manually when computer is there. Every one wants his/her work to be done by
computer automatically and displaying the result for further manipulations.
A book shop uses a personal computer to maintain the inventory of books that
are being sold at the shop. The list includes details such as author, title, price,
publisher, stock position, etc. Whenever a customer wants a book, the
shopkeeper inputs the title and author of the book and the system replies
whether it is in the list or not. If it is not, an appropriate message s displayed. If
book is in the list, then the system displays the book details and asks for number
of copies. If the requested copies are available the, total cost of the books is
displayed; otherwise the message “Required copies not in stock” is displayed.
1
Existing System:
While Modifying a record, the person will have to first search the record
and then make changes of that particular record in every related register.
PROPOSED SYSTEM
The following documentation is a project the “Book Rental System”. It is a
detailed summary of all the drawbacks of the old system and how the new
proposed system overcomes these shortcomings. The new system takes into
account the various factors while designing a new system. It keeps into the
account the Economical bandwidth available for the new system. The foremost
thing that is taken care of is the Need and Requirements of the User.

REQUIREMENT ANALYSIS
This process is adopted when management of the system development,
Personnel decide that the particular system needs improvement. The system
development life cycle is the set of activities, carried out by the analyst,
designers and users to develop and implement a system. The systems that are
present in the nature follow common life cycle pattern. For example consider the
raining system. Initially the rain falls into the river, river flows into sea, the sea
water evaporates to form vapors, the vapors form clouds which again bring rain.
Similarly consider a man made system initially a system is analyzed, designed
and made operational by the efforts of system analysis. After successful
operation or a number of users, the system becomes less and less effective by
change in the environment. So these changes have to be incorporated in to the
system by minor modifications. So the general activities from the life cycle of the
system are given below:
Selection and identification of the system to be studied
Preliminary study
Defining the system
Design and development of the system

Implementation of the system
PROJECT TO BE DEVELOPED IS GOING TO ACHIEVE THE
FOLLOWING OBJECTIVES:
Helps in eliminating the individual maintenance of the record of storage of
books in any educational institute
Helps in reducing maintenance time by automatically shifting /. Storing
the information in relevant modules.
Helps in fast retrieval or instant availability of information required.
Provides flexibility to bring the required change in a record case
of
modification or deletion or seeking information of queries.
Helps in reducing manual power requirement to a single person.

SYSTEM ANALYSIS
System analysis is a process of gathering and interpreting facts,
diagnosing problems and the information to recommend improvements on the
system. It is a problem solving activity that requires intensive communication
between the system users and system developers. System analysis or study is
an important phase of any system development process. The system is studied
to the minutest detail and analyzed. The system analyst plays the role of the
interrogator and dwells deep into the working of the present system. The system
is viewed as a whole and the input to the system are identified. The outputs from
the organizations are traced to the various processes. System analysis is
concerned with becoming aware of the problem, identifying the relevant and
decisional variables, analyzing and synthesizing the various factors and
determining an optimal or at least a satisfactory solution or program of action.
A detailed study of the process must be made by various techniques like
interviews, questionnaires etc. The data collected by these sources must be
scrutinized to arrive to a conclusion. The conclusion is an understanding of how
the system functions. This system is called the existing system. Now the existing
system is subjected to close study and problem areas are identified. The
designer now functions as a problem solver and tries to sort out the difficulties
that the enterprise faces. The solutions are given as proposals. The proposal is
then weighed with the existing system analytically and the best one is selected.
The proposal is presented to the user for an endorsement by the user. The
proposal is reviewed on user request and suitable changes are made. This is
loop that ends as soon as the user is satisfied with proposal.
Preliminary study is the process of gathering and interpreting facts, using
the information for further studies on the system. Preliminary study is problem
solving activity that requires intensive communication between the system users
and system developers. It does various feasibility studies. In these studies a
rough figure of the system activities can be obtained, from which the decision
about the strategies to be followed for effective system study and analysis can
be taken.
11
Existing System
Lack of security of data.
More man power.
Time consuming.
Consumes large volume of pare work.
Needs manual calculations.
No direct role for the higher officials.

The aim of proposed system is to develop a system of improved facilities.
The proposed system can overcome all the limitations of the existing system.
The system provides proper security and reduces the manual work.
Security of data.
Ensure data accuracy’s.
Proper control of the higher officials.
Minimize manual data entry.
Minimum time needed for the various processing.
Greater efficiency.
Better service.
User friendliness and interactive.
Minimum time required.

FEASIBILITY STUDY
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 the time that
spend on it. Feasibility study lets the developer foresee the future of the project
and the usefulness. A feasibility study of a system proposal is according to its
workability, which is the impact on the organization, ability to meet their user
needs and effective use of resources. Thus when a new application is proposed
it normally goes through a feasibility study before it is approved for development.
The document provide the feasibility of the project that is being designed
and lists various areas that were considered very carefully during the feasibility
study of
this project
such
as Technical,
Economic
and
Operational
feasibilities. The following are its features:
A.
TECHNICAL FEASIBILITY
The system must be evaluated from the technical point of view
first. The assessment of this feasibility must be based on an outline
design of the system requirement in the terms of input, output, programs
and procedures. Having identified an outline system, the investigation
must go on to suggest the type of equipment, required method
developing the system, of running the system once it has been designed.
Technical issues raised during the investigation are:
Does the existing technology sufficient for the suggested
one?
Can the system expand if developed?
The project should be developed such that the necessary functions
and performance are achieved within the constraints. The project is
developed within latest technology. Through the technology may become
obsolete after some period of time, due to the fact that never version of
same software supports older versions, the system may still be used. So
there are minimal constraints involved with this project. The system has
been developed using Java the project is technically feasible for
development.
13
B.
ECONOMIC FEASIBILITY
The developing system must be justified by cost and benefit.
Criteria to ensure that effort is concentrated on project, which will give
best, return at the earliest. One of the factors, which affect the
development of a new system, is the cost it would require.
The following are some of the important financial questions asked
during preliminary investigation:
The costs conduct a full system investigation.
The cost of the hardware and software.
The benefits in the form of reduced costs or fewer costly
errors.
Since the system is developed as part of project work, there is no
manual cost to spend for the proposed system. Also all the resources are
already available, it give an indication of the system is economically
possible for development.
C.
BEHAVIORAL FEASIBILITY
This includes the following questions:
Is there sufficient support for the users?
Will the proposed system cause harm?
The project would be beneficial because it satisfies the objectives
when developed and installed. All behavioral aspects are considered
carefully and conclude that the project is behaviorally feasible.

ABOUT OPERATING SYSTEM
Windows XP is a line of operating systems developed by Microsoft for use
on general purpose computer systems, including home and business desktops,
notebook computers and media centers. The letters ‘XP’ stand for experience.
Windows XP is the successor to both Windows 2000 and Windows Me and is
first consumer oriented operating system produced by Microsoft to be built on
the Windows NT kernel and architecture.
The most common editions of operating systems are Windows XP home
edition, which is targeted at home users, and Windows XP professional, which
has additional features such as, support for Windows server domain and two
physical processors and is targeted at power users and business clients.
Windows XP Tablet PC edition is designed to run the ink-aware Tablet PC
platform. Two separate 64 bit versions of Windows XP were also released,
Windows XP 64 bit edition for IA-64(Itanium) processors and Windows XP
Professional x64 edition for x86-64 processors.

SOFTWARE DESCRIPTION
Microsoft Visual Basic.Net
Visual Basic .NET (VB.NET or VB .NET) is a version of Microsoft's Visual Basic
that was designed, as part of the company's .NET product group, to make Web
services applications easier to develop. According to Microsoft, VB .NET was
reengineered, rather than released as VB 6.0 with added features, to facilitate
making fundamental changes to the language. VB.NET is the first fully objectoriented programming (OOP) version of Visual Basic, and as such, supports
OOP concepts such as abstraction, inheritance, polymorphism, and aggregation.
In the Visual Basic NET design time environment, the first thing to concentrate
on is that strange, big square in the top left. That's called a form. It's actually the
pretty bit of your programme, the part that others will see when they launch your
masterpiece. Granted, it doesn't look too attractive at the moment, but you'll
soon discover ways to lick it into shape.
To run the form, try this:
From
the menu bar, click Debug
From
the drop down menu, click Start
Alternatively,
Your
press the F5 key on your keyboard
programme is launched
Congratulations! You have now created your very first programme. It should look
like this:
16
Click the Red X on the form to stop it from running. You will then be returned to
the software environment.
Things like buttons, textboxes, and labels are all things that you can add to your
Forms. They are know as Controls, and are kept in the Toolbox for ease of use.
The Toolbox can be found on the left of the screen. In the picture below, you can
see the toolbox icon next to Form1:
To display all the tools, move your mouse over the toolbox icon. You'll see the
following automatically appear:
There are seven categories of tools available.
The toolbox you'll be working with first is the
Common Controls toolbox. To see the tools,
click on the plus symbol next to Common
Controls. You'll see a long list of tools:
As you can see, there are an awful lot of tools to
choose from! For this first section, we'll only be
using the Button, the TextBox and the Label.
If you want to keep the toolbox displayed, click
the Pin icon next to the X. To close the toolbox,
simply move your mouse away.
In the next part, we'll see how to add a textbox to
the form.
17
How to Add a Control to your VB .NET Forms
Let's start by adding a textbox to our form. With the tools displayed, do the
following:
Locate the TextBox tool
Double click the icon
A textbox is added to your
form
The textbox gets added to the top left position of
your form. To move it down, hold your mouse
over the textbox and drag to a new position:
Notice the small squares around the textbox.
These are sizing handles. Move your mouse
over one of them. The mouse pointer turns into
an extended line with arrowheads. Hold your left
mouse button down and drag outwards. The
textbox is resized. Play around with the sizing
handles until you're happy with the size of your
textbox.
One thing you will notice is that you can't make
the size any higher, but you can make it wider. The reason why you can't make it
any higher is because the default action of a textbox is to have it contain only a
single line of text. If it's only going to contain one line of text, Microsoft reasoned,
there's no reason why you should be able to change its height. A textbox can
only be made higher if it's set to contain multiple lines of text. You'll see how to
do this soon.
Create
two
more
textboxes by double
clicking on the textbox
icon in the toolbar (Or
Right-click
on
the
selected textbox and
choose Copy. Then
Right-click on the Form
and choose Paste.)
Resize them to the
same size as your first
one
Line them up one
below the other with
space in between
Try to create something
that looks like the one below

Microsoft Access 2003.
Microsoft Access is the default database of Microsoft Visual Basic.
Microsoft Access 2003 provides many new features that make working with data
and designing a database even easier.
Microsoft Access Database is a
collection of data and objects related to particular topic or purpose. Microsoft
Access Database may contain tables; queries, forms, reports, macros modules
and shortcuts top data access pages.
Microsoft Access is a Relational Database Management System. Using
Access we can organize our data according to subject and can store information
about how different subject are related. In general MS-Access database can
have several small tables.
Microsoft Office Access, previously known as Microsoft Access, is a relational
database management system from Microsoft that combines the relational
Microsoft Jet Database Engine with a graphical user interface and software
development tools. It is a member of the 2007 Microsoft Office system.
Access can use data stored in Access/Jet, Microsoft SQL Server, Oracle,
or any ODBC-compliant data container (including MySQL and PostgreSQL).
Skilled software developers and data architects use it to develop application
software. Relatively unskilled programmers and non-programmer "power users"
can use it to build simple applications. It supports some object-oriented
techniques but falls short of being a fully object-oriented development tool.
Access was also the name of a communications program from Microsoft,
meant to compete with ProComm and other programs. This proved a failure and
was dropped. Years later Microsoft reused the name for its database software.
Access is used by small businesses, within departments of large
corporations, and by hobby programmers to create ad hoc customized desktop
systems for handling the creation and manipulation of data. Access
can
be
used as a database for basic web based applications hosted on Microsoft's
Internet Information Services and utilizing Microsoft Active Server Pages ASP.
Most typical web applications should use tools like ASP/Microsoft SQL Server or
the LAMP stack.
19
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. The data is the purpose of any database and must be
protected.
The database design is a two level process. In the first step, user
requirements are gathered together and a database is designed which will meet
these requirements as clearly as possible. This step is called Information Level
Design and it is taken independent of any individual DBMS.
In the second step, this Information level design is transferred into a design
for the specific DBMS that will be used to implement the system in question.
This step is called Physical Level Design, concerned with the characteristics of
the specific DBMS that will be used. A database design runs parallel with the
system design. The organization of the data in the database is aimed to achieve
the following two major objectives.
Data Integrity
Data independence
Normalization is the process of decomposing the attributes in an application,
which results in a set of tables with very simple structure. The purpose of
normalization is to make tables as simple as possible. Normalization is carried
out in this system for the following reasons.
To structure the data so that there is no repetition of data, this helps in
saving.
To permit simple retrieval of data in response to query and report request.
To simplify the maintenance of the data through updates, insertions,
deletions.
To reduce the need to restructure or reorganize data which new
application requirements arise.
20
RELATIONAL DATABASE MANAGEMENT SYSTEM (RDBMS):
A relational model represents the database as a collection of relations.
Each relation resembles a table of values or file of records. In formal relational
model terminology, a row is called a tuple, a column header is called an attribute
and the table is called a relation. A relational database consists of a collection of
tables, each of which is assigned a unique name. A row in a tale represents a
set of related values.
RELATIONS, DOMAINS & ATTRIBUTES:
A table is a relation. The rows in a table are called tuples. A tuple is an
ordered set of n elements. Columns are referred to as attributes.
Relationships have been set between every table in the database. This
ensures both Referential and Entity Relationship Integrity. A domain D is a
set of atomic values. A common method of specifying a domain is to
specify a data type from which the data values forming the domain are
drawn. It is also useful to specify a name for the domain to help in
interpreting its values. Every value in a relation is atomic, that is not
decomposable.
RELATIONSHIPS:
Table relationships are established using Key. The two main keys of
prime importance are Primary Key & Foreign Key. Entity Integrity and
Referential Integrity Relationships can be established with these keys.
Entity Integrity enforces that no Primary Key can have null values.
Referential Integrity enforces that no Primary Key can have null values.
Referential Integrity for each distinct Foreign Key value, there must exist
a matching Primary Key value in the same domain. Other key are Super
Key and Candidate Keys.
Relationships have been set between every table in the database. This
ensures both Referential and Entity Relationship Integrity.

SYSTEM IMPLEMENTATION
Implementation is the stage in the project where the theoretical design is
turned into a working system. The implementation phase constructs, installs and
operates the new system. The most crucial stage in achieving a new successful
system is that it will work efficiently and effectively.
There are several activities involved while implementing a new project they are
End user training
End user Education
Training on the application software
System Design
Parallel Run And To New System
Post implementation Review
End user Training:
The successful implementation of the new system will purely upon the
involvement of the officers working in that department. The officers will be
imparted the necessary training on the new technology.
End User Education:
The education of the end user start after the implementation and testing is
over. When the system is found to be more difficult to under stand and complex,
more effort is put to educate the end used to make them aware of the system,
giving them lectures about the new system and providing them necessary
documents and materials about how the system can do this.
Training of application software:
After providing the necessary basic training on the computer awareness,
the users will have to be trained upon the new system such as the screen flows
and screen design type of help on the screen, type of errors while entering the
data, the corresponding validation check at each entry and the way to correct the
data entered. It should then cover information needed by the specific user or
group to use the system.
Post Implementation View:
The department is planning a method to know the states of t he past
implementation process. For that regular meeting will be arranged by the
concerned officers about the implementation problem and success
TESTING
64
Testing is a process of executing a program with the interest of finding an
error. A good test is one that has high probability of finding the yet undiscovered
error. Testing should systematically uncover different classes of errors in a
minimum amount of time with a minimum amount of efforts. Two classes of
inputs are provided to test the process
A
software
configuration
that
includes
a
software
requirement
specification, a design specification and source code.
A software configuration that includes a test plan and procedure, any
testing tool and test cases and their expected results.
Testing is divided into several distinct operations:
1.
Unit Testing
Unit test comprises of a set tests performed by an individual
program prior to the integration of the unit into large system. A program
unit is usually the smallest free functioning part of the whole system.
Module unit testing should be as exhaustive as possible to ensure that
each representation handled by each module has been tested. All the
units that makeup the system must be tested independently to ensure
that they work as required.
During unit testing some errors were raised and all of them were
rectified and handled well. The result was quiet satisfactory and it worked
well.
2.
Integration Testing
Integration testing is a system technique for constructing the
program structure while at the same time conducting tests to uncover
errors associated with interfacing. The objective is to take unit tested
modules and build a program structure that has been dictated by design.
Bottom-up integration is the traditional strategy used to integrate the
components of a software system into functioning whole. Bottom-up
integration consists of unit test followed by testing of the entire system. A
sub-system consists of several modules that communicated with other
defined interface.
65
3.
Validation Testing
After validation testing, software is completely assembled as a
package, interfacing errors that have been uncovered and corrected and
the final series of software test; the validation test begins. Steps taken
during software design and testing can greatly improve the probability of
successful integration in the larger system. System testing is actually a
series of different tests whose primary purpose is to fully exercise the
compute –based system.
4.
Recovery Testing
It is a system that forces the software to fail in a variety of ways
and verifies that the recovery is properly performed.
5.
Security Testing
It attempts to verify that protection mechanisms built into a system
will in fact protect it from improper penetration. The system’s security
must of course be tested from in vulnerability form frontal attack.
6.
Stress Testing
Stress tools are designed to confront programs with abnormal
situations. Stress testing executes a system in a manner that demands
resources in abnormal quantity and volume.
7.
Black Box Testing
Black box testing is done to find out the following information as
shown in below:
Incorrect or missing functions.
Interface errors.
Errors or database access.
Performance error.
Termination error.
The mentioned testing is carried out successfully for this
application according to the user’s requirement specification.
8.
Test Data Output
After preparing test data, the system under study is tested using
the test data. While testing the system using test data, errors are again
uncovered and corrected by using above testing and corrections are also
noted for future use.
66
CONCLUSION & FUTURE ENHANCEMENT
The new realities of Digital information processing require that access is
provided in a widely distributed manner, and it is up to the user to locate what is
needed. The ability to call up all relevant information at the click of a mouse is a
researcher’s dream. In future we develop a Book-bank monitoring system project
aims at developing a software infrastructure that enables those who manage and
maintain such collections to make them publicly available. The entire
University/College/ department/ community stands to benefit greatly from an
online book-bank monitoring system. The system will enable the update,
retrieval, deletion, and generation of status reports according to the existing
demands.
