Library Management System Design

The project brief is to develop a computerized library management system that enables the management of books, addition and deletion of students, check availability of books, issuing books to students, and maintain records. The system requirements include an operating system (Windows 7, XP, or Ubuntu), processor (Intel core processor), hard disk space (2.5 GB), memory (500 MB RAM), and information stored in a file format.

Library Management System
ABSTRACT
This project is based on the management of the book's information in the library and among the
student. The management of books in old days are done manually. Librarian did such kind of
thing by keeping all the records in the file in text format. This kind of information management
leads to the problem as the size of the file increases after the small period. If the librarian wants
to notify some students about the book, then he may have to put the notice on the notice board.
After some period keeping track on every book is difficult task. This project will help in
overcome such problems. The announcement of notice is done on account of the student.
Addition and deletion of student can be done easily.
INTRODUCTION
The main aim of the project is to issue book, adding new books to the heap, student addition and
deletion, check the availability of books, issuing books to the student, and maintain records. This
project is generally medium in size. It is used to tell the description of the various books and to
whom they are allocated. This computer based library management system. The basic similarity
between old and this library management is that all the credentials are store in the file. File
management techniques are used to keep track on books and how to manage them. Al these
things are done by the administrator who is librarian. He has the authority to add and delete the
information of the books and the students.
SYSTEM REQUIREMENTS
Operating system Window 7, Window XP, UBUNTU
Processor Intel core processor for better performance

DESCRIPTION AND JUSTIFICATION
USE CASE DIAGRAM

Library Management System
In this the user has to sign up first give their credentials. All the information of the user who is
student are accessible to the administrator name librarian. If the user want to borrow the book
from the library then he/she may have to login first from their password and id after the can add
books in their account. Such information are also available to the librarian. Librarian can add the
books to the heap of book and he can also delete the book from the user account and from the
heap of books as well.
CLASS DIAGRAM

Library Management System
In this class diagram relation is shown among the different classes like books, users, and
LMSMain. In this one enumeration class is also used. Name of the enumeration class is
UserType. According to this class diagram. There are three users namely student, librarian, and
guest who can access many books if available. User can do multiple operation on their data and
the books tht has been borrowed. User can also set the quantity of the book. Book can be find out
by the name of the book and author name.
ACTIVITY DIAGRAM

Library Management System
This diagram shows the flow of the information from the starting point to the end point. In this
diagram the has to login first from their credentials and then he check the availability of book in
the library and if the book is not available then user log out and the program stops but if the book
is available user can add the book to its account and log out. This information of the user is also
available to the administrator and the librarian so that they can edit the information if required.
OOPS CONCEPT
1. public class User implements Serializable{}
java.io.Serializable interface helps in creating the serializability of the class. This interface
serialized the states of the class. All subtypes of a serializable class are themselves serializable.
The serialization interface has no methods or fields and serves only to identify the semantics of
being serializable.
2. public class Book implements Serializable{}
Classes are used in this which is one of the major concepts of the OOP’s concept. Access
modifier is used in it to define the accessibility of the variable.
ADDITIONAL FUNCTIONALITY
@Override
public int hashCode() {}
@Override
public boolean equals(Object obj) {}
Hashcode is being used because of the use of Set andHashMaps. So for that it will possible to
check whether two books is equal or not. So two methods Equals and HashCode are overridden.

Library Management System
For ObjectOutputStream,is used to serialized the objects and not writing them in inhuman
readable form.
CONCLUSION AND FUTURE SCOPE
This project is the console based project and provides the library management system in the
computerized form. It is benefited for the staff, student, and the librarian to keep track on the
books and distribute the books among the different students. This project has the facility of the
login and logOut and in this all the credentials are store in the file format that is not directly
readable to any user. Security is provided to the user's credentials. In future we can also provide
the GUI to this project and make the interface more attractive.
