Overview
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.

Audience
Anyone needing to access relational databases from Java programs.

Prerequisites
Intermediate knowledge of Java programming and a basic understanding of relational databases are recommended.

Number of Days
3 days
