News > Object/Relational Mapping and Transparent Object Persistence for Java and SQL Databases

Relational Persistence For Idiomatic Java

Hibernate is a powerful, ultra-high performance object/relational persistence and query service for Java. Hibernate lets you develop persistent classes following common Java idiom - including association, inheritance, polymorphism, composition and the Java collections framework. The Hibernate Query Language, designed as a "minimal" object-oriented extension to SQL, provides an elegant bridge between the object and relational worlds. Hibernate also allows you to express queries using native SQL or Java-based Criteria and Example queries. Hibernate is now the most popular object/relational mapping solution for Java.

All SQL database management systems are supported. Of course, Hibernate integrates elegantly (and without restrictions) with all popular J2EE application servers and web containers. Hibernate can also be used in standalone Java applications. See our complete introduction for more information and our current road map.

Hibernate is Free Software. The LGPL license is sufficiently flexible to allow the use of Hibernate in both open source and commercial projects (see the LicenseFAQ for details). Commercial support and training for Hibernate is available through JBoss, Inc.

If you are a first time user, follow this road map to learn Hibernate quickly.

An early draft of the EJB 3.0 specification was made public today. The next generation of EJB is focused on simplification of the programming model and many concepts from Hibernate have been used to shape the new EJB entity bean part of the spec. If you have comments or new ideas, contact the expert group.

Have a look at our road map for more information about the future of Hibernate.
