The DataNucleus project provides products for the management of application data in a Java environment. Our aim is to provide good quality open source products to handle data in all of its forms, wherever it is stored. This goes from persistence of data into heterogeneous datastores, to providing methods of retrieval using a range of query languages, and eventually on to the analysis of data and tools for managing data quality.

DataNucleus Access Platform is the baseline product providing persistence of Java objects to a range of datastores using JDO and JPA APIs and permitting various query languages.
