Re: Next round of DB discussion

I hate many-to-many. Do we really need to have it for objects? Classical tree is way easier to maintain..

OK. Object - Object relationships. They are all many-to-many.

I.E. topic contains multiple problems. Yet problem can be used in
different topics
(i.e. in different courses). Same applies to Explanations,
topic-to-course, and
dialog-of-texts objects.

I don't remember about others.
Ah, yes, tests. (We need to add them - they are just collection of
problems, with extra
info related to how to pass them, etc - see model layer class diagram).
