When I read this quickly, it seems to make sense, but when I really try to imagine what this means, I come out at the same place every time: if you’ve written a “method for inserting application objects into the database”, you’ve written an ORM.   Databases don’t store “application objects”, they store rows.  So there has to be “ORM” in there.

replying to Markus -

SQLAlchemy’s ORM is only an optional component of the SQLAlchemy database toolkit overall.  If you would like a very mature and well proven SQL abstraction layer that does not provide any design directions whatsoever (not to mention much better performance than the ORM), please consider SQLAlchemy Core: http://docs.sqlalchemy.org/en/rel_0_9/core/index.html.
