In the Zope 2 worlds we have dedicated database adapters

wonderful present called SQLAlchemy that abstracts the different

z3c.zalchemy and z3c.sqlalchemy... basically they deal with connection
handling, mapper handling and integration with the Zope transaction
system. Would it make sense to replace all different Zope DAs with
a generic DA on top of one of the z3c.* wrappers? I think it would not
be too hard to write such a DA...or am I missing something? Thoughts?

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?

The subject says Zope 2:-)
