Do you have practical experience working with the Hibernate ORM library?

Yes, Hibernate is a popular ORM library for Java that allows working with a database through objects rather than directly via SQL. It automatically converts Java objects to database records and vice versa.

Example of using Hibernate:

@Entity
public class User {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long id;
    private String name;
    // getters and setters
}

// In service code
Session session = sessionFactory.openSession();
Transaction tx = session.beginTransaction();
User user = new User();
user.setName("Ivan");
session.save(user);
tx.commit();
session.close();

Hibernate manages sessions and transactions, which simplifies working with data and increases code portability across different DBMS.
