Library Management System

1
INTRODUCTION
The project titled Library Management System is Library management software
for monitoring and controlling the transactions in a library .The project “Library
Management System” is developed in java, which mainly focuses on basic operations
in a library like adding new member, new books, and updating new information,
searching books and members and facility to borrow and return books.
“Library Management System” is a windows application written for 32-bit
Windows operating systems, designed to help users maintain and organize library. Our
software is easy to use for both beginners and advanced users. It features a familiar
and well thought-out, an attractive user interface, combined with strong searching
Insertion and reporting capabilities. The report generation facility of library system
helps to get a good idea of which are the books borrowed by the members, makes
users possible to generate reports’ hard copy.
The software Library Management System has four main modules.
 Insertion to Database Module – User friendly input screen
 Extracting from Database module – Attractive Output Screen
 Report Generation module – borrowed book list & Available book list
 Search Facility system – search for books and members

SYSTEM ANALYSIS
EXISTING SYSTEM:
System Analysis is a detailed study of the various operations performed by a
system and their relationships within and outside of the system. Here the key
question is- what all problems exist in the present system? What must be done to
solve the problem? Analysis begins when a user or manager begins a study of the
program using existing system.
During analysis, data collected on the various files, decision points and
transactions handled by the present system. The commonly used tools in the system
are Data Flow Diagram, interviews, etc. Training, experience and common sense are
required for collection of relevant information needed to develop the system. The
success of the system depends largely on how clearly the problem is defined,
thoroughly investigated and properly carried out through the choice of solution. A
good analysis model should provide not only the mechanisms of problem
understanding but also the frame work of the solution. Thus it should be studied
thoroughly by collecting data about the system. Then the proposed system should be
analyzed thoroughly in accordance with the needs.
System analysis can be categorized into four parts.
 System planning and initial investigation
 Information Gathering
 Applying analysis tools for structured analysis

 Feasibility study
 Cost/ Benefit analysis.
In our existing system all the transaction of books are done manually, So taking more
time for a transaction like borrowing a book or returning a book and also for searching of
members and books. Another major disadvantage is that to preparing the list of books
borrowed and the available books in the library will take more time, currently it is doing as a
one day process for verifying all records. So after conducting the feasibility study we decided
to make the manual Library management system to be computerized.

PROPOSED SYSTEM
Proposed system is an automated Library Management System. Through our
software user can add members, add books, search members, search books, update
information, edit information, borrow and return books in quick time. Our proposed system
has the following advantages.
 User friendly interface
 Fast access to database
 Less error
 More Storage Capacity
 Search facility
 Look and Feel Environment
 Quick transaction
All the manual difficulties in managing the Library have been rectified by implementing
computerization.

FEASIBILITY ANALYSIS
Whatever we think need not be feasible .It is wise to think about the feasibility of any
problem we undertake. Feasibility is the study of impact, which happens in the organization
by the development of a system. The impact can be either positive or negative. When the
positives nominate the negatives, then the system is considered feasible. Here the feasibility
study can be performed in two ways such as technical feasibility and Economical Feasibility.
Technical Feasibility:
We can strongly says that it is technically feasible, since there will not be much difficulty in
getting required resources for the development and maintaining the system as well. All the
resources needed for the development of the software as well as the maintenance of the
same is available in the organization here we are utilizing the resources which are available
already.
Economical Feasibility
Development of this application is highly economically feasible .The organization needed
not spend much m one for the development of t he system already available. The only thing is
to be done is making an environment for the development with an effective supervision. I f
we are doing so , we can attain the maximum usability of the corresponding resources .Even
after the development , the organization will not be in a condition to invest more in t he
organization .There fore , the system is economically feasible.

SYSTEM DESIGN
INPUT DESIGN
Input design is the process of converting user-oriented input to a computer based
format. Input design is a part of overall system design, which requires very careful attention
.Often the collection of input data is the most expensive part of the system. The main
objectives of the input design are …
1. Produce cost effective method of input
2. Achieve highest possible level of accuracy
3. Ensure that the input is acceptable to and understood by the staff.
Input Data
The goal of designing input data is to make enter easy, logical and free from errors as
possible. The entering data entry operators need to know the allocated space for each field;
field sequence and which must match with that in the source document. The format in which
the data fields are entered should be given in the input form .Here data entry is online; it
makes use of processor that accepts commands and data from the operator through a key
board. The input required is analyzed by the processor. It is then accepted or rejected. Input
stages include the following processes
 Data Recording
 Data Transcription
 Data Conversion
 Data Verification
11
 Data Control
 Data Transmission
 Data Correction
One of the aims of the system analyst must be to select data capture method and
devices, which reduce the number of stages so as to reduce both the changes of errors and
the cost .Input types, can be characterized as.
 External
 Internal
 Operational
 Computerized
 Interactive
Input files can exist in document form before being input to the computer. Input
design is rather complex since it involves procedures for capturing data as well as inputting it
to the computer.
OUTPUT DESIGN
Outputs from computer systems are required primarily to communicate the results of
processing to users. They are also used to provide a permanent copy of these result for latter
consultation .Computer output is the most important and direct source of information to the
users. Designing computer output should proceed in an organized well through out the
manner. The right output must be available for the people who find the system easy o use.
The outputs have been defined during the logical design stage. If not, they should defined at
the beginning of the output designing terms of types of output connect, format, response etc,
Various types of outputs are
12
 External outputs
 Internal outputs
 Operational outputs
 Interactive outputs
 Turn around outputs
All screens are informative and interactive in such a way that the user can full fill his
requirements through asking queries.
DATABASE DESIGN
The general theme behind a database is to handle information as an integrated whole.
A database is a collection of interrelated data stored with minimum redundancy to serve
many users quickly and effectively. After designing input and output, the analyst must
concentrate on database design or how data should be organized around user
requirements. The general objective is to make information access, easy quick,
inexpensive and flexible for other users. During database design the following objectives
are concerned:-
 Controlled Redundancy
 Data independence
 Accurate and integrating
 More information at low cost
 Recovery from failure
 Privacy and security
 Performance
 Ease of learning and use
13
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.
14
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
SOFTWARE TESTING
Is the menu bar displayed in the appropriate contested some system related features
included either in menus or tools? Do pull –Down menu operation and Tool-bars work
properly? Are all menu function and pull down sub function properly listed ?; Is it possible to
invoke each menu function using a logical assumptions that if all parts of the system are
correct, the goal will be successfully achieved .? In adequate testing or non-testing will leads
to errors that may appear few months later.
This create two problem
1. Time delay between the cause and appearance of the problem.
2. The effect of the system errors on files and records within the system
15
The purpose of the system testing is to consider all the likely variations to which it will be
suggested and push the systems to limits.
The testing process focuses on the logical intervals of the software ensuring that all
statements have been tested and on functional interval is conducting tests to uncover errors
and ensure that defined input will produce actual results that agree with the required results.
Program level testing, modules level testing integrated and carried out.
There are two major type of testing they are
1) White Box Testing.
2) Black Box Testing.
White Box Testing
White box some times called “Glass box testing” is a test case design uses the control
structure of the procedural design to drive test case.
Using white box testing methods, the following tests where made on the system
A) All independent paths within a module have been exercised once. In our system, ensuring
that case was selected and executed checked all case structures. The bugs that were
prevailing in some part of the code where fixed
b) All logical decisions were checked for the truth and falsity of the values.
16
Black box Testing
Black box testing focuses on the functional requirements of the software. This is black box
testing enables the software engineering to derive a set of input conditions that will fully
exercise all functional requirements for a program. Black box testing is not an alternative to
white box testing rather it is complementary approach that is likely to uncover a different
class of errors that white box methods like..
1) Interface errors
2) Performance in data structure
3) Performance errors
4) Initializing and termination errors
17
CONCLUSION
Our project is only a humble venture to satisfy the needs in a library. Several user
friendly coding have also adopted. This package shall prove to be a powerful package in
satisfying all the requirements of the organization.
The objective of software planning is to provide a frame work that enables the
manger to make reasonable estimates made within a limited time frame at the
beginning of the software project and should be updated regularly as the project
progresses. Last but not least it is no the work that played the ways to success but
