Apache Cayenne is an open source persistence framework, providing object-relational mapping (ORM) and remoting services.

Cayenne seamlessly binds one or more database schemas directly to Java objects, managing

  • atomic commit and rollbacks
  • SQL generation
  • joins
  • sequences

and more. With Cayenne's Remote Object Persistence, those Java objects can even be persisted out to clients via Web Services.

Full details and documentation can be found at http://cayenne.apache.org
