Now (in Zope2) we have things like ZOracleDA (DCOracle2), ZPsycopgDA
etc. that are adapters to these specific databases. They're based on
In Zope3 there are also such adapters eg. one using cx_Oracle. They're
based on Zope3 rdb module.
What do you mean by 'replacing' them? You want wrapper build for
z3c.* to be used instead of ZRDB (rdb)?
You're talking about Zope2 or Zope3 too?
I don't fully understand what you want to do...
