[opencms] Re: [opencms-dev] OpenCms in the future?

[Alexander Wallace]

I have had time to see how the persistence layer of opencms is implemented... 
redesigning the persistence layer may be a big task, but, (and i ask this to 
the ones that have seen it), what is the possibility of writing a hibernate 
implementation wrapped around whatever is currently used to implement another 
database? and if that was the case, would it take advantage of all the 
hibernate features to not only enhance db support but also performance, etc? 
Even if at the beginning we don't have UI in the setup to configure a 
hibernate configuration file, and one would have to manually do so if 
hibernate was selected to handle the database...

what are the thoughts on this?
