Lab1Books is a RESTful API for managing books, built using Jakarta EE 11, WildFly Preview, and PostgreSQL. It provides endpoints for retrieving, filtering, creating, updating, and deleting books. The API includes validation, error handling, and pagination for efficient data management. It does not use Spring Boot, and database operations are handled via Jakarta Data repositories.

Features Retrieve all books or fetch a specific book by ID. Filter books by author, title, and genre. Combine filters for author & title or author & genre. Create new books with validation to prevent duplicates. Update existing books with partial updates supported. Delete books safely with proper error handling.
