Library Management System

CHAPTER 1 INTRODUCTION 1.1 ABOUT LIBRARY MANAGEMENT SYSTEM Library management System (LMS) provides a simple GUI (graphical user interface) for the Library Staff to manage the functions of the library effectively. Usually when a book is returned or issued, it is noted down in a register after which data entry is done to update the status of the books in a moderate scale. This process takes some time and proper updation cannot be guaranteed. Such anomalies in the updation process can cause loss of books. So a more user friendly interface which could update the database instantly, has a great demand in libraries.

The goal of this project is to provide simplicity as well as security and efficiency to the management. Its main objective is to provide all the functions of the library along with support of barcode reader. The contemporary system stores the database information on a local computer, which can‟t be updated and accessed on a remote computer or a computer in the library network.

1.2 PROBLEM DEFINITION  The Library Management System implements databases to make the existing system more efficient.  It is difficult to catch defaulters in a usual library system, but LMS solves this problem by providing messages to the administrator about the fine to be paid and books to be returned.  When a book is to be borrowed, its barcode is read and is fed to LMS.  When the administrator tries to issue a book to a member, LMS checks whether the member is allowed to borrow books respective to his limit.  LMS also checks whether the book to be issued is a reference book or not. If the book is a reference book, it cannot be issued.  If the book has no restrictions it is issued to the member, and also the member‟s details is updated with the books that he has just borrowed.  Any member can search a book with its title name, or author‟s name.

2

CHAPTER 2 SYSTEM ANALYSIS 2.1 EXISTING SYSTEM  In the existing system, the transactions of the books are recorded in a local computer and the information cannot be accessed by other members of the library  In some libraries, the transactions are recorded in a register, and then later they are fed into the computer by a Data Entry Operator.  This type of maintenance usually causes some errors due to delay in updation and mistakes during large data entry.  Basically there is no security, i.e. any person can perform transactions other than the administrator.

2.2 PROPOSED SYSTEM  In Library Management System, the processing of transactions is done with the help of computer.  LMS provides a very simple GUI.  Through LMS, updating to the database is very efficient and instantly done.  It provides a guest login for the members to view details about the available books and allows them to search for a particular book.  LMS provides security (i.e. only the administrator can update any information to the database) 3

 Barcode Readers can be installed to the system and respective plug-in can be installed to the LMS for effective and easy transactions.  Error generation for Authentication purpose and also for constraints to the members on the number of books allowed for a particular member.  Member can be a Student, or Lecturer or Non teaching Staff, and respective limits for borrowing books for each type of member is set (i.e. students can borrow up to 3 books and lecturers & non-teaching staff can borrow up to 5 books).  According to update anomalies, proper errors are generated in exclamation and dialog boxes.  The data can be updated to a server on the network. There can be many clients around the library from which the users can check for books available.

CHAPTER 4 SYSTEM DESIGN 4.1 INTRODUCTION LMS implements two types of users in the system. One is the administrator who has the total control over the database and the other is the guest account through which one can view the READ ONLY terminals of the database. 4.1.1 Functions given to the Administrator: 1.

Administration:

a)

Adding a new member:

The administrator can add new members to the library. He has to enter the following details. i)

Patron ID

ii)

Patron Name

iii) Designation (Student, Lecturer, Non Teaching staff) iv) Date of Joining v)

Date of Expiry of membership

A unique patron id is given to each member of the library b)

Modifying the member details:

The administrator has the option to modify the details of a member i)

Name

ii)

Designation

iii) Imposing or Clearing Fine iv) Renewing the membership c)

Removing a member

6

The administrator has the rights to remove a member from the library. Most importantly LMS doesn‟t allow a member to be removed from the library if the member has books to return or fine to be paid. The member can be removed either with reference to his name or his patron id which can also be scanned from his ID card through a barcode reader. 2.

Tech Processing

a)

Primary Catalogue

This menu gives options to the administrator to add new books to the library The following details of the book are to be entered. i)

Item Barcode

ii)

Title

iii) Author iv) Physical Description (no. of pages) v)

Reference or not (Reference or Ordinary)

vi) ISBN b)

Modify Catalogue

This form displays the all the books of the library and gives the option to the administrator to modify the details of a book. The following details can be modified. i)

Title

ii)

Author

iii) Reference or not iv) ISBN v)

Physical Description (no. of pages)

The barcode can‟t be modified. 3.

Circulation

a)

Check In

By check in option, a book can be returned to the library. The barcode of the book is required, which can be scanned by the barcode reader. b)

Check Out 7

When a book is check out request is given, LMS verifies whether the person is allowed to borrow more books or not. A student can borrow only up to 3 books, whereas a Lecturer or Non teaching Staff can borrow up to 5 books. An error is generated if the person is not allowed. 4.

4.2 DATABASE DESIGN The LMS implements Oracle as the Backend and thus the database schema is defined and modified through Oracle SQL. The LMS consists of two tables to store all the information, and all the necessary information is extracted from these tables through appropriate queries in VB. The tables are BOOK and PATRON. The schemas are as follows. PATRON Name

Null?

PATRON_ID

DOJ is the date of join and EXPIRY is the date of expiry of membership. NOB is the no. of books borrowed by the member. FINE represents the amount of fine imposed on the member in Rs. BOOK Name

CHAPTER 7 SYSTEM TESTING Testing is one of the important steps in the software development phase. Testing is performed to identify errors and is an integral part of the entire development and maintenance process. The Library Management System has been put under rigorous testing so as ensure the correctness of its design. The two basic testing strategies that were used: 1. Unit Testing. 2. Integration Testing. 7.1 UNIT TESTING Unit testing was conducted to verify the functional performance of each modular component of the software. Unit testing focuses on the smallest unit of software design i.e. the module. White-box testing were heavily employed for unit testing. 7.1.1 Login Screen Step

CHAPTER 8 CONCLUSION

LMS simplifies the manual work load and is helpful in the effective transactions of the library. The work load of the administrator is reduced to a great extent by computerized transactions and instant information about the books in the library. The members of the library are provided a very interactive interface to search for the books by title as well as author. The administrator can instantly make changes to the database. LMS provides messages whenever required viz. limit reached of member to borrow books, error when trying to remove member who still has to pay fine. Thus the mini project LMS by implementing VB as front end and Oracle as back end was achieved and tested accordingly.
