A simple console-based application built to practice Jakarta Persistence API (JPA) with Hibernate, using an H2 in-memory database. The system allows full CRUD operations for Authors and Books, demonstrating entity relationships, DAO patterns, transaction control, and basic persistence configuration.
- Create new author
- List all authors
- Find author by ID and display their books
- Update author information
- Delete an author and cascade delete their books
- Create new book
- List all books
- Find a book by ID
- Update book information
- Delete a book
- Java 25

The main goal of this project was to practice and solidify essential JPA & HIBERNATE concepts by building a full CRUD application. Additionally, the project serves as training in core Java, object-oriented programming, and fundamental database management concepts.
