[rules-users] Does the Rete Graph recognize associations independently?

Hi, one doubt I've had while writing DRL scripts and also with others is: A { B b C c D d }; If The rules are to be Written over A, B, C Then should one assert B, C & D also? ---> Answer yes! Ok, now that we've asserted them, in the Rule if one uses: A.b; does the Rete graph recognize it as a node of A or B? I suspect it is 'A' Hence... I take a safe approach and write rules on B,C independently but then ensure those objects are reverse associated with A. This increases the risk of objects not being released for GC (depends on JVM) if not nullified (and breaking the circular associations). So whats the best approach in designing objects for the Engine? Thanks, Arjun
