Status

PB API (Persistence Broker API)

The PB API implementation is stable.

OTM API (Object Transaction Manager API)

The OTM Object Transaction Manager API is in beta status with this release.

ODMG API

The ODMG API implementation is stable, but there some known issues - see release-notes

Note

OQL is currently not fully implemented (Aggregations and Method Invocations).
ODMG implicit locking is partly implemented but does currently not maintain transaction isolation properly. To achieve safe transaction isolation client application must use explicit lock acquisition.

JDO API

By providing a plugin to the SUN JDO Reference Implementation we provide a complete JDO 1.0.1 prototype O/R mapping tool. A complete Apache licensed JDO implementation is scheduled for OJB 2.0.
