Introduction to the Java Persistence API

The Java Persistence API provides an object/relational mapping facility to Java developers for managing relational data in Java applications. Java Persistence consists of four areas:

The Java Persistence API
The query language
The Java Persistence Criteria API
Object/relational mapping metadata
