Course Description

Hibernate is a 3 day 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. 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.
