About the Java Persistence API (JPA)

Java Persistence API (JPA) is an object-relational mapping (ORM) framework, that is, it maps objects to relational databases. JPA provides the standard for object-relational mapping in the Java language. JPA can use either Standard or Enterprise Edition Java.

EclipseLink is one implementation of JPA. It is an open source project, and it works with a large number of databases or platforms. Actian Corporation has added PSQL as an EclipseLink JPA platform.

The PSQL database Platform file has been submitted to EclipseLink and is awaiting full promotion. For the latest information about its status and download, go to PSQL website and navigate to the SDK section.
