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?
As I gathered from discussions, one should first think to use direct object references for such relations.
A module which might help in this is http://svn.zope.org/zc.extrinsicreference/ Would be interesting with what solution you will end. __Janko -- Janko Hauser email: [EMAIL PROTECTED] mobile: +49 1721 641552
