HOWTO on writing your own persistence layer

Folks, where can I find documents about good design practices when
developing your own persistence layer to map from OO to RDBMS??

I know there are several free tools available in the market, but I'd like to
hack a bit on the subject and improve the one I have here (made I few months
ago and use it on a few projects...)

Thanks,

Scott Ambler has written some papers on the subject. I think
www.cetus-links.org also has pointers. I would also recommend the mapping
patterns site maintained by Wolfgang Keller at www.objectarchitects.de.

O/R mapping is done for you internally in FirstSQL/J. See
http://www.firstsql.com/javaobjects.shtml

We believe in the future all RDBMS will automatically map OO types
internally. There is no need to learn a 3rd party tool for this effort.

Hi,

Well, this depends on how deep you want to go in your persistence layer.
Try:
