FYI, there *is* vist/identity implementation that based on  SQLAlchemy,
see savisit.py/saprovider.py.

As noted by others catwalk/model designer doesn't work with SA yet, but

You can have a database abstraction API (e.g. such as DatabaseFacade

using an ORM tool or access database directly via DB-API.
