Well since ORM has all these following meanings
ORM is an acronym for:
Object role modeling
Object-relational mapping
Operational Risk Management a U.S. Navy concept for safety in operations
planning
Online research methods
Orosomucoid
Outsourcing Relationship Management
Online Reputation Management
ORM is also:
the IATA airport code for Sywell Aerodrome in Northamptonshire, England
I am not sure exactly what you want. I mean you mentioned a lot of database
mapping libraries so I am hoping that is what you are looking for. We use
sqlite3 for our db only because it has some easy ways to just request whole
tables into dictionaries in python. I am not sure if you would consider
doing sql requests and having it auto port it into a dictionary an ORM but
to each their own.

Hmm, is there an ORM for python that has the same name as the SQLite command
line client?
