DataNucleus (formerly known as Java Persistent Objects JPOX) is an open source project (under the Apache 2 license) which provides a series of software products around data management in Java.
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 specifications and the Java Persistence API 1.0, 2.0 specifications, 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), document stores (MongoDB) as well as other types of datastores (LDAP). It is designed using OSGi technology.
DataNucleus Access Platform is the persistence layer behind Google App Engine for Java, and VMForce (cloud offering from Salesforce.com and VMWare).
