DataNucleus supports persisting/retrieving objects to/from JSON datastores
(using the datanucleus-json plugin).
Support for JSON is in its early stages and will be enhanced in future releases.
If you wish to help out in this effort either by contributing or by sponsoring particular
functionality please contact us via the DataNucleus Forum.
The following persistence properties will connect to JSON at a URL
So you create your PersistenceManagerFactory or
EntityManagerFactory with these properties.
Thereafter you have the full power of the JDO or JPA APIs at your disposal, for your
Access Platform allows you to query the objects in the datastore using the following
JDOQL - language based around the objects that are persisted and
using Java-type syntax
JPQL - language based around the objects that are persisted and
using SQL-like syntax
