I'm working on the scea 2 assignment, and I'm having a decision problem regarding changing the BDM or not.
In the use case diagram provided I have 2 actors that in all 4 use cases doesn't directly interact; because of this I got the conclusion that the application is a mediator between the two actors that don't have to know each other.
In the BDM , the 2 entities are related with a common object but the relations are unidirectional like A <- Common -< B; meaning B is aware of A but A is not aware of B.
I want to change the BDM like A <- Common -> B.

I would get point discounts for this ?

many thanks,
