Description

Given that JDO's charter is to be datastore-agnostic, a JDO object store should be high on the list. It supports both relational and non-relational databases, including object databases, NoSQL data stores and *literally* anything else.

By leveraging the plugins of DataNucleus, the Apache-licensed open source JDO reference implementation, the following object stores below can be supported out of the box.

RDBMS (all major vendors)
DB4O
LDAP
Excel
XML
Neodatis
JSON
ODF
HBase

See http://www.datanucleus.org/plugins/ for more info.

Google's BigTable could also be supported thanks to their Google AppEngine for Java persistence solution, which is a DataNucleus plugin, enabling Isis- & JDO-based apps to run on GAEJ.

Note that DN also supports Joda & javax.time datetime types as well.
