Suggestions for simple persistance in a web app?

[Kevin Dahlhausen]

I'm getting ready to experiment with Webware.  I'd like to use a
simple database or somewhat efficient persistant store as I'll be
using the CGI-one shot version of webware and don't want to also have
to load a complete database into memory.  So, mysql, postgress, and
such are too heavy. I'll be lucky to find a way to run Webware on an
isp's site anyway.  Are there any alternative database libraries for
python out there?  SQL's ok, python objects to disk in some rational
way would work too, if I could load them without pulling every object
into memory first.  Thanks
