Hibernate framework
Hibernate framework is an object/relational mapping library (ORM) for the Java language. It provides a object/relational persistence query service. With hibernate, you can map an object-oriented domain model to a traditional relational database. It is an open source product developed by Red Hat. Data is one of the most valuable assets a company has, and with Hibernate you can put it to good use in Java applications. In this section on Hibernate, get news, research, and tutorials on the Hibernate framework and read tips and advice to find out how it can help your applications make the best use of the data available.
