The MySQL driver does not know anything about 'objects', you can do 
plain SQL with it, that's all. It's not a framework or an OO to RDMS bridge.

MySQL itself also knows nothing about objects, it's a plain relational 
I understand Postgres advertises as an OO database, or a RDBMS to OODBMS 
bridge, I can't really say if that makes it more useful in connection 
with Smalltalk.

Then there is GLORP, originially developed for VW. It's a persistency 
framework or OO to RDBMS bridge.
Last time I checked it was still under development, and as I understand 
it, not yet production ready.
GLORP, AFAIK, only works with Postgres as a backend, at least for the 

So far I don't know of any solutions that make dealing with persistency 
a breeze to work with, it's still a major unsolved issue.

The easiest way, and actually the most practical one by far for most 
needs, is to use the image itself for persistency, keep storing it, 
snapshots, on an interval basis.

Good luck!
