DataNucleus provides a series of software products around data management using the Java programming language.

DataNucleus Access Platform is an open source and fully compliant implementation of the Java Data Objects (JDO) 1.0, 2.0, 2.1, 2.2 specifications and the JPA1 specification, providing transparent persistence of Java objects. It also provides preview features of the forthcoming JPA2 specification. It supports persistence to all of the major relational database management systems on the market today, supporting all of the main object-relational mapping (ORM) patterns, allows querying using either JDOQL, JPQL or SQL, and comes with its own byte-code enhancer. It allows persistence to RDBMS, db4o, LDAP, XML, Excel, NeoDatis and JSON datastores. It is designed with OSGi technology.

DataNucleus Access Platform is available under an Apache 2 license.
