Library management system project in java with source code

Library management system project in java with source code and project report. Library management project in java is a web application using JSP, Servlet, MYSQL, and eclipse.

Library management is a web-based Java application that automates the working of a library or book center that manages and maintains records of the books in the book library.

The librarian holds various activities like adding new books, Viewing all the books, Adding a new student in the system managing the book records ETC.

Objective of library management

The objective of the library management system is to design a web application in java that can manage a library. An easy and user-friendly interface that is easy to operate and understand for the students as well as for librarians. An Easy platform to manage books and the records of books like the issued book and the student records.

Library management system project in java

The Library management system in java is developed using JSP and servlets. It uses MYSQL to manage the backend activities. This java project is using maven to manage the dependencies and follows MVC architecture to manage the project resources.

It uses a tomcat server for deployment and we can use eclipse, STS, or Netbeans as IDE to run this project.

Let’s understand the features and functionalities of the library management system in detail according to the module and application actors.

So there are two main actors of the application Admin and User.

1)Admin(librarian):

The librarian can Add/edit/update the record of students.

The librarian can Add/edit/update the record of Books.

The librarian can Search Books.

The librarian can Search Students.

The librarian can Issue books and library cards.

2)User(Student):

A student can register in the system

A student can view his profile(Edit/Update).

A student can check the history of issuing books.

Technologies and Platform

Library management software is being designed and developed on an Open Platform i.e. J2EE. MYSQL will be used to maintain the database. To achieve a high degree of modularity, scalability, and maintainability, it is recommended to adopt n- tier architecture while designing the Library management System.

Accordingly, it is proposed that the entire application development logic, database logic, and presentation logic shall be segregated. It is proposed that the LMS software package shall be running on Apache Tomcat Web Server. The Web Server will be responsible for rendering the JSP pages and the result is shown back to the end-user.

Hardware requirements

4 GB of RAM with 20GB HDD.

Software requirements

OS platform which supports JDK(Java) Like windows, mac, or Linux.
JDK 1.8
Eclipse/STS/Netbeans.
MYSQL v5.6 or above.
Tomcat 8.5 or above.
