Subject Re: PersistenceManagerFactory configuration for flat-file database
Date Wed, 20 May 2009 00:49:40 GMT
Hi Ozvena,

I think you'll find that HSQL also store it data in human readable 
format for some table types.  If that satisfies your needs, then 
DataNucleus will definitely do the job for you as I believe it supports 
HSQL.

Cheers,

David
