DataNucleus (formerly known as Java Persistent Objects JPOX) is an open source project (under the Apache 2 license) which provides software products around data management in Java. The DataNucleus project started in 2008[1] (the JPOX project started in 2003 and was relaunched as DataNucleus in 2008 with broader scope).

DataNucleus Access Platform is a fully compliant implementation of the Java Data Objects (JDO) 1.0, 2.0, 2.1, 2.2, 3.0, 3.1, 3.2 specifications (JSR 0012,[2] JSR 0243[3]) and the Java Persistence API (JPA) 1.0, 2.0, 2.1, 2.2 specifications (JSR 0220,[4] JSR 0317,[5] JSR 0338[6]), providing transparent persistence of Java objects. It supports persistence to the widest range of datastores of any Java persistence software, 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 relational datastores (RDBMS), object-based datastores (db4o, NeoDatis ODB), document-based storage (XML, Excel, OpenDocument spreadsheets), web-based storage (JSON, Google Storage, Amazon Simple Storage Service), map-based datastores (HBase, Google's Bigtable, Apache Cassandra), graph-based datastores (Neo4j), document stores (MongoDB) as well as other types of datastores (e.g. LDAP). Its plugins are OSGi-compliant so can be used equally in an OSGi environment.
DataNucleus Access Platform is also utilised by the persistence layer behind Google App Engine for Java,[7] and VMForce (cloud offering from Salesforce.com and VMWare).[8]
