python - SQLAlchemy-like relationships without SQLAlchemy -

-

sqlalchemy gives me nice relationships between objects. when change 1 object's member, it's automatically added other object's list, etc. - don't want use db. i'd keep objects in memory. there module gives kind of behavior without using sqlalchemy?

not knowing full context of project working on, can use sqlalchemy sqlite database or easier hold in memory. issue if hold things in memory once restart process lose data.
