SQLAlchemy's ability to create database objects is a convenience only. I'm using SQLAlchemy within an application that mostly uses a different ORM. All tables and other database objects are created by hand-written SQL. I use SQLAlchemy's Declarative extension to define mapped classes for those tables which I care about. Sometimes, I use SQLAlchemy's introspection to build queries. Declarative, introspection and the non-SQLAlchemy parts of the system all coexist just fine.
