Subject [jira] [Commented] (ISIS-14) Add JDO 3.1 object store in order to support any datastore
Date Tue, 17 Jul 2012 07:14:35 GMT


Dan Haywood commented on ISIS-14:

Hi Andy,
Thanks for dropping by.  Don't know if it's just a coincidence or not, you making this remark,
because this issue has been lying fallow for a long while.  However, I am as it happens actively
working on this issue now.  And yes, we had noticed 3.1 is imminent, and so we'll implement
against it.
I've changed the title of this issue to reflect.

> 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.
