Subject [jira] [Commented] (ISIS-14) Add JDO 3.0 object store in order to support any datastore
Date Mon, 16 Jul 2012 17:44:34 GMT


Andy Jefferson commented on ISIS-14:

If this issue is seriously contemplated, use of DataNucleus v3.1 would be advisable (final
release very soon) since it provides GAE support as well as more standard java types out of
the box.

> 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
> Excel
> Neodatis
> HBase
> See 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.
