| This article explains how to use EclipseLink, the reference implementation for the Java Persistence API (JPA). The usage of EclipseLink will be demonstrated for Java applications outside the JaveEE environment.

The Java Persistence API simplifies the life of a developer to a great degree. It permits the developer to work with objects rather then with SQL statements.|
