Documentation for libgeronimo-jpa-2.0-spec-java

Documentation for the Java Persistence API that is the Java API for the management of persistence and object/relational mapping for Java EE and Java SE environments.

The goal of this specification is to provide an object/relational mapping facility for the Java application developer using a Java domain model to manage a relational database.

Persistence in this context covers three areas:

 - The API itself, defined in the javax.persistence package.
 - The Java Persistence Query Language (JPQL).
 - Object/relational metadata.

The Java Persistence 2.0 specification addresses improvements in the areas of domain modeling, object/relational mapping, EntityManager and Query interfaces, and the Java Persistence query language. It adds an API for criteria queries, a metamodel API, and support for validation.

This package contains only API of JSR-317 spec. Apache OpenJPA and EclipseLink are implementations of this spec.
