Hi,

there was a discussion about the bad idea to simulate a relational database in ZODB using indexes and unique ids. So I wonder what's the "correct" way to express a n:m realtionship between objects.


For example: I have projects and articles. An article might be relevant for multiple projects and a project might have multiple relevant articles. Could I simply give each object a list containing the related objects? Or is this kind of circular reference a problem?

regards,
Achim
