Oops... Sorry. I probably projected my expectations on your answer.
Sure. When your data is not relational (or, representing it as relations doesn't help you getting to it) you should consider other forms of representing it.
I am very fond of Zope and its underlying ZODB storage (and the connectors that allow it to store documents on mostly anything else), but it's very Python-centric and Python, as much as I love it, is not the perfect solution to every problem.
