DataNucleus Access Platform is committed to supporting all relevant Java persistence standards. It already fully supports the JDO1, JDO2, JDO2.1 and JPA1 standards and is committed to meeting the JDO2.2 and JPA2 standards when they are available.

DataNucleus Access Platform supports access to the vast majority of RDBMS available today. In addition it supports db4o, a popular object datastore. If those datastores aren't what you use you additionally have the choice of LDAP, Excel documents!, and upcoming support for XML Databases, NeoDatis ODB and JSON (RESTful).

DataNucleus Access Platform utilises an OSGi plugin mechanism meaning that it is highly configurable and extensible, not just by provided DataNucleus plugins, but also by your company where you have some utility that you would like to connect. It comes with a series of published APIs allowing you wide access to the access process.

Most competing products only support one type of datastore, or one API, and with it restrict what query language you have available to you. DataNucleus Access Platform provides full flexibility, allowing use of JDO XML/Annotations or JPA XML/Annotations with either JDO or JPA APIs, with your choice of datastore, and also your choice of query language. Flexibility!
