What is the main goal of using the ORM library Hibernate in projects?

The main goal of using ORM library Hibernate is to simplify database work by providing object-relational mapping (ORM). Hibernate allows developers to work with the database through Java objects instead of manually writing SQL queries.

Advantages of Hibernate:

• Automatic conversion of objects to tables and back.
• Management of sessions and transactions.
• Caching for performance improvement.
• Support for various DBMS without changing code.

Example: instead of writing an SQL query to select users, you can simply call session.get(User.class, id) to get a User object.
