Hibernate is an open source object/relational (OR) persistence and query service for Java. Hibernate lets you develop persistent classes following common Java idioms - 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 OR mapping solutions for Java, and it has become a de facto standard in Java OR mapping.  JBoss has integrated Hibernate into its JEMS (Java Enterprise Middleware System) product line.  

The Java Persistence API (EJB 3) specification derives a great deal of its architecture from Hibernate, and the Hibernate annotations are compatible with the Java Persistence annotations.  This promises to make Hibernate an even more important technology.

This course covers everything you need to know to begin working with Hibernate in a very short time.  It covers all the important concepts necessary to access and update data stored in relational databases.  It includes an extensive series of labs to exercise all major capabilities.

All labs are done with the Eclipse IDE Java EE version, and the lab instructions include detailed directions for using it. It is also available for other major IDEs, such as IntelliJ IDEA.

Supported Platforms: Java 5, Java 6, Eclipse, IntelliJ IDEA, other major platforms
