Hi,

We are trying to migrate a very old application on Zope 2.9, first we thought to migrate to Python Products and then upgrade Zope.

We don't know what's the best way to deal with SQL querys in Python products. He is some options we are evaluating:

- SQLAlchemy, leaving behind ZSQLMethods e Zope DA's
- Psycopg
- Python code access a Zope DA inside Zope

So, what you guys think?

Thanks.
