What tasks does the ORM library Hibernate solve in Java applications?

The Hibernate ORM library in Java addresses the object-relational mapping (ORM) task. It allows developers to work with the database through Java objects rather than writing SQL queries directly.

Main tasks of Hibernate:

• Automatic conversion of Java objects to database records and vice versa.
• Management of object lifecycle and their states (persistent, detached, etc.).
• Caching data to improve performance.
• Support for transactions and management of relationships between objects (e.g., one-to-many relationships).
• Generation of SQL queries based on operations with objects.

This simplifies development, reduces errors, and increases code portability across different DBMSs.
