Hibernate Core for Java(Linux) 3.2.5.ga

Hibernate Core for Java generates SQL for you, relieves you from manual JDBC result set handling and object conversion, and keeps your application portable to all SQL databases.
Hibernate provides transparent persistence, the only requirement for a persistent class is a no-argument constructor. You dont even need classes, you can also persist a model using Maps of Maps, or just about anything else. You dont even need tables, Hibernate can map entities and particular properties to SQL expressions.
Hibernate offers sophisticated query options, you can write plain SQL, object-oriented HQL (Hibernate Query Language), or create programatic Criteria and Example queries. Hibernate can optimize object loading all the time, with various fetching and caching options.
Hibernate adapts to your development process, no matter if you start with a design from scratch or work with an existing database, and it will support any application architecture. Combined with Hibernate EntityManager and Hibernate Annotations you can use Hibernate as a certified Java Persistence provider.
