ACKNOWLEDGEMENT

I would like to express my sincere gratitude to my project supervisor which is Ms. Vartika Sharma who guided me a lot throughout the project development. Without her guidance, I think I would not with this project. In addition, she gives me logic problems related to the project which is very useful to me. I would also like to thank my principal sir for providing us the lab which has all the facilities for developing this project.

Our Librarian Sir also give his full co-operation when I went to ask the present working system of our library.

My Friend circle also helps me a lot to overcome my problems. In trying to solve some logic errors I also get helped from my tuition teacher.

At last I want to thank my parents for their cooperation and helping me at every stage of my life.


Library Managemen

t System


ABSTRACT

In Library, Librarian is the admin. Staff used to maintain record of one who is member of that library and the books that he/she had borrowed a book from that library. They also have to maintain a particular time period after which they have to pay some fine for their borrowed book. If someone lost some books then they have to pay price plus some fine for the book which is also maintained by them.

So In order for Proper functioning Library staff have to maintain record for library members as well for the books they have in their library.

In library with lakhs of books and hundreds f their member it is hard for the staff such lots of data. In order to get information about any member they have to fetch many records which is time consuming and also need more man power in big libraries. It is also difficult for staff to secure lots of data.

Nowadays, we can use computers to came out of such difficulties. A simple library management system can do all these things without much man power nor it needed much time to fetch data about a particular book or library members. The proposed system can modify, delete, insert ad search record within few seconds and can also calculate the fine that an individual had to pay.

1. INTRODUCTION

I. Background of the Study:- I’ve seen librarian struggling with records while when we go to issue or deposit a book. This manual system is time consuming and record can even be easily lost. This gives me an idea to develop a program which can be economically or behaviorally feasible for the users.

Little development in this program can be done so that it can be easily used in other record keeping like in hotels, hospitals, etc.

II. Statement of Problems and Objectives:-Problems:-

Some of the problems being faced in manual system are as follows:1. Fast report generation is not possible.2. Tracing a book is difficult.3. Information about issue/return of the books are not properly maintained.4. No central database can be created as information is not available in

database.

Objective:-

1. It Reduces Paperwork.2. Reduce the workload of employee.3. Faster retrieval of information about the desired book.4. Provide facility for proper monitoring reduces paper work and provide data security.

5. All details will be available on just few seconds.


III. Hypothesis:-

I’ve started this program with an objective to develop it for keeping record of books for student in library with ten books can be issued per student. But I was failed because it makes program too complex so I’ve developed this program with a limitation that a student can only issue one book.

IV. Significance of Project:-

This Project is suitable for small and medium size library. It is use by librarian and library admin to manage the library using a computerized system. This system was developed and designed to help librarian record every transaction so that the problem such as record missing will not be happened. A centralized storage system behind it will help a lot for maintaining a record. Modification on the available data will be easier and there is no needto fill the whole record for just a small change. This proposed system is moreefficient and quick in order to find a record .

V. Delimitation and Limitation Of Project:-

Delimitation:- 1.It is more efficient than present day manual system. 2. Reduced Data Insecurity. 3.Reduces Paper Work. 4.Reduces Work load and need much less time to find a particular record.

Limitation:-1.It work on very old language platform and hence most of the computer had to install turbo C++ for the execution of the program.2.It doesn’t work on database which can be very useful in efficiency and speed processing for our records.


2. REVIEW OF THE RELATED LITERATURE

Data Type Description

OfstreamThis data type represents the output file stream and is used to create files and to write information to files.

IfstreamThis data type represents the input file stream and is used to read information from files.

Fstream

This data type represents the file stream generally, and has the capabilities of both ofstream and ifstream which means it can create files, write information to files, and read information from files.

To perform file processing in C++, header files <iostream> and <fstream> must be included in your C++ source file.

Opening a File:A file must be opened before you can read from it or write to it. Either the ofstream or fstream object may be used to open a file for writing and ifstream object is used to open a file for reading purpose only.

Following is the standard syntax for open() function, which is a member of fstream, ifstream, and ofstream objects.

void open(const char *filename, ios::openmode mode);

Here, the first argument specifies the name and location of the file to be opened and the second argument of the open() member function defines the mode in which the file should be opened.

Mode Flag Description

ios::appAppend mode. All output to that file to be appended to the end.

ios::ateOpen a file for output and move the read/write control to the end of the file.

ios::in Open a file for reading.


ios::out Open a file for writing.

ios::truncIf the file already exists, its contents will be truncated before opening the file.

For example if you want to open a file in write mode and want to truncate it in case it already exists, following will be the syntax:

ofstream outfile;outfile.open("file.dat", ios::out | ios::trunc );

Similar way, you can open a file for reading and writing purpose as follows:

fstream afile;afile.open("file.dat", ios::out | ios::in );

Closing a File:

When a C++ program terminates it automatically closes flushes all the streams, release all the allocated memory and close all the opened files. But it is always a good practice that a programmer should close all the opened files before program termination.

Following is the standard syntax for close() function, which is a member of fstream, ifstream, and ofstream objects.

void close();

Writing to a File:

While doing C++ programming, you write information to a file from your program using the stream insertion operator (<<) just as you use that operator to output information to the screen. The only difference is that you use an ofstream or fstream object instead of the cout object.

Reading from a File:

We read information from a file into your program using the stream extraction operator (>>) just as you use that operator to input information from the keyboard. The only difference is that you use an ifstream or fstream object instead of the cin object.

II. Requirement Statement – System Requirement


For Development

Turbo C++, Borland C++.

Windows XP, Vista, 7,8 or Mac OSx or equivalent.

Processor – Intel P4 or Later

256 of RAM or higher

For Execution

Turbo C++, Borland C++ .

Windows XP, Vista, 7,8 or Mac OSx or equivalent.

Processor – Intel P4 or Later

256 MB of RAM or higher

III. Feasibility Study

A. Technical

It needed a pc with the above given requirements and a turbo C++ software for its execution.


B. Economical

I have uses the resources of my lab to develop this program and there is light interface for the user and hence I can say that it can be easily feasible for even small libraries with minimal cost.

C. Behavioral

This software is an effort to reduce man work in library. The users had to give just input while other works like calculation, updating, inserting and usually all most all the functions of a record it can do. I even use an easy use of English language so that user will not face difficulty for operating the program. This project can be executable on C++ platform all you need to install turbo C++ with the above requirement .The menu driven program help the user to choose whatever they need and good use of retrieval in the program will provide a better interaction interface for the user.

IV. SYSTEM ANALYSIS

Some of the problems being faced in manual system are as follows:1. Fast report generation is not possible.2. Tracing a book is difficult.3. Information about issue/return of the books are not properly

maintained.4. No central database can be created as information is not available

in database.


Proposed system provides with following solutions :1. It provides "better and efficient" service to members.2. Reduce the workload of employee.3. Faster retrieval of information about the desired book.4. Provide facility for proper monitoring reduce paper work and

provide data security.5. All details will be available on a click.

5.CONCLUSION AND RECOMMENDATION

I. CONCLUSION:-

This project aims to replace the manual work of making a record and we think it would be able in its motto of doing so. We have included certain functions for deleting record, updating a record, viewing records for the simplicity of the user.

II. RECOMMENDATION:-

We hereby invite any recommendations or suggestions for the betterment of this project. There are some limitations of this project as is the case with all projects. No system till date has been designed which is errorless or without limitations.
