This project is a library management system developed in Java using persistence based on JPA (Java Persistence API) and integration with the PostgreSQL database. The system allows management of a library catalog and its loans, providing functionalities to add, remove, and search for books and magazines, as well as to track loans.

• Catalog Management: Addition and removal of books and magazines from the catalog.
• Advanced Search: Search by ISBN, publication year, author, and title.
• Loan Management: User registration, tracking borrowed items, and start and end loan dates.
• Loan Tracking: View currently borrowed items and overdue loans.

The project includes:

• Catalog Classes: Classes to represent books and magazines, with distinct attributes for each type of item.
• Data Access Object (DAO) Classes: Classes for data access and management, including CRUD operations and queries.
• Integration with PostgreSQL: Configuration and integration with the PostgreSQL database for persistence.

1. Setup PostgreSQL: Ensure PostgreSQL is installed and running on your local machine. If not installed, download and install it from PostgreSQL Downloads.

2. Database Configuration: Open the persistence.xml file and modify the following properties according to your PostgreSQL configuration:

   <property name="javax.persistence.jdbc.url" value="jdbc:postgresql://localhost:5432/LibraSysDB"/>
   <property name="javax.persistence.jdbc.user" value="postgres"/>
   <property name="javax.persistence.jdbc.password" value="12345"/>
   

• Replace localhost with your PostgreSQL server hostname if it's not running locally.
• Modify the port number 5432 if your PostgreSQL server is running on a different port.
• Replace LibraSysDB with the name of your database.
• Update the javax.persistence.jdbc.user and javax.persistence.jdbc.password properties with your PostgreSQL username and password.

3. Run the Application: Compile and run the Java application to start the library management system. Ensure that the PostgreSQL server is running before running the application.
4. Interact with the System: Once the application is running, you can interact with it using the provided functionalities to manage the catalog and loans.

• Java 8 or higher
• PostgreSQL database
