I may have missed the explanation above, if initially john has no cars, tom has two cars, and bob has one; how does the MV solution later handle each car having 0 to many manfacturers?
Because dbd's data model is very general, systematic, normalized, holy, etc; one simply adds those attributes like this:
(new gm 'mfg)
(new honda 'mfg)
(set (. 'aston 'martin) mfgdBy honda)
(set (. 'aston 'martin) mfgdBy gm)
