Description:

The Java Persistence API (JPA) was introduced as part of the Java EE 5 platform to simplify the development of Java applications using data persistence and to unify the community behind a standard lightweight persistence API. The JPA specification was based on the best ideas from existing persistence technologies but now provides existing Hibernate, TopLink and Kodo customers with a standard model for object/relational mapping. JPA 101: Java Persistence Explained is a fundamentals guide to the ins and outs of JPA, the Java object/relational mapping and persistence standard for both Java SE and Java EE applications. The book covers the basics of working with the JPA, JPA annotations, Entity Manager, JPA Query Language, and tools. As you work through the tutorial, you will build a simple Maven 2 project and Hibernate object model.
