The DataNucleus project provides products for the management of application data in a Java environment. DataNucleus provides open source (Apache 2 licensed) products supporting data access using all standardised APIs (JDO, JPA) to a very wide-range of datastores (RDBMS, ODBMS, Map-based, Web-based, documents, etc) supporting querying using a range of query languages. This flexibility of API and datastore is not available in any other persistence tool Since the API's are standard and so reasonably well-known this reduces the learner curve, and you can use the same API for all of your data. It's time to free up your data access layer

Access Platform is our baseline product. It is the most standards-compliant Open Source Java persistence product in existence. It is fully compliant with the JDO1, JDO2, JDO2.1, JDO2.2, JDO3, JPA1 and JPA2 Java standards. It also complies with the OGC Simple Feature Specification for persistence of geospatial Java types to RDBMS. It utilises an OSGi-based plugin mechanism meaning that it is extremely extensible. It is also free for use. The benefits for your business are significant. Version 3.0 [Read More] | [Download] | [Get Started] Version 2.2 [Read More] | [Download] | [Get Started]
