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.
