Library-Management-System

Fully functioning Library Management desktop application to:

• Allow librarians to add, edit, delete, and view Users, Books, Copies, Borrowings, Librarians, and Publishers via a Swing GUI.
• Let regular users view the complete catalog, check available titles, and consult their own borrowing history.
• Persist data using JPA annotations and Hibernate, modeling one-to-many, many-to-one, and one-to-one relationships.
• Ensure all entities support full CRUD, with delete operations restricted when referential constraints exist.
• Provide comprehensive unit tests (JUnit 5) and integration tests (H2 in-memory) covering CRUD operations, relationships, business logic (e.g., borrowing limits, concurrency), and edge cases.
• Document all classes and methods with JavaDocs and publish as an HTML package.
