I have some confusions on the solution approach. Please corret me if I'm wrong in the following.
(i) If certain cardinalities, relationships are unclear in the given BDM , can we fix those problem areas by identifying and providing valid assumption as the solution or can it be only solved through UML diagram?
(ii)Can I make the changes(ex: In order management domain, changing the entity 'manufacturer' as attribute to 'product' entity) in the given BDM entities in order to depict them properly in class diagram solution?
(iii)Does the assumption point get marked if solution is not fully shown in UML compliance or it lead to failure of whole deliverables?
