Library Management System

A Java-based Library Management System that allows users to register, login, add books (librarian role), view all books, and borrow books (member role). The system uses JDBC for database operations.

Features

• User Registration and Login: Users can register with a username, password, and role (librarian or member) and login to the system.
• Librarian Functions:
  • Add new books to the library.
  • View all books available in the library.
• Member Functions:
  • View all books available in the library.
  • Borrow books from the library.

Getting Started

Prerequisites

• Java Development Kit (JDK) 8 or higher
• JDBC driver for your database
• A database (e.g., MySQL, PostgreSQL, etc.)

Setting Up the Database

1. Create a database for the library system.
2. Create the necessary tables:

   CREATE TABLE Users (
       user_id INT AUTO_INCREMENT PRIMARY KEY,
       username VARCHAR(255) NOT NULL,
       password VARCHAR(255) NOT NULL,
       role VARCHAR(50) NOT NULL
   );
   
   CREATE TABLE Books (
       book_id INT AUTO_INCREMENT PRIMARY KEY,
       title VARCHAR(255) NOT NULL,
       author VARCHAR(255) NOT NULL,
       isbn VARCHAR(50) NOT NULL,
       available_copies INT NOT NULL,
       total_copies INT NOT NULL
   );
   
   CREATE TABLE BorrowedBooks (
       id INT AUTO_INCREMENT PRIMARY KEY,
       user_Id INT NOT NULL,
       book_Id INT NOT NULL,
       borrow_Date DATE NOT NULL,
       FOREIGN KEY (user_Id) REFERENCES Users(user_id),
       FOREIGN KEY (book_Id) REFERENCES Books(book_id)
   );
   

Configuration

1. Update the DatabaseConnection class with your database connection details.

   public class DatabaseConnection {
       private static final String URL = "jdbc:your_database_url";
       private static final String USERNAME = "your_database_username";
       private static final String PASSWORD = "your_database_password";
   
       public static Connection getConnection() throws SQLException {
           return DriverManager.getConnection(URL, USERNAME, PASSWORD);
       }
   }

Running the Application

1. Clone the repository:

   git clone https://github.com/your-username/library-management-system.git
   cd library-management-system

2. Compile and run the application:

   javac LibraryManagementSystem.java
   java LibraryManagementSystem

Usage

User Registration

1. Run the application.
2. Select "Register" from the main menu.
3. Enter a username, password, and role (librarian or member).

User Login

1. Run the application.
2. Select "Login" from the main menu.
3. Enter your username and password.

Librarian Functions

• After logging in as a librarian, you can:
  • Add new books to the library.
  • View all books in the library.

Member Functions

• After logging in as a member, you can:
  • View all books in the library.
  • Borrow books from the library.

Additional Notes

• Ensure you have your DatabaseConnection class properly set up for your specific database.
• Modify the database schema creation SQL to match your database's syntax if necessary.
• Room for Improvement: There is potential to expand functionality by adding more CRUD operations (update and delete books, manage users, etc.).
• Input Sanitization: Input validation and sanitization can be enhanced to ensure robustness and security of the application.
