Hi,

I'm working on Big Smokes assignment. Business Domain Model (BDM) lists Standard/Petite/Flavored cigars as entities. I feel that when it comes down to class diagram and persistence Standard/Petite/Flavored is just a category.
I've done excessive study online of cigar selling stores, all cigar have pretty much same attributes regardless whether they are flavored or petite.
Also, I've seen that in real life there are much more categories than just these 3. So it's likely that as soon as BigSmoles online store goes into UAT phase it would become a must-have feature. Therefore I feel that I need to design something that would be extensible enough to allow that.

I've read somewhere that my class diagram *must* depict all entities from the BDM. If I go with "categories" I would not have classes like
FlavoredCigar <<@entity>>
StandardCigar <<@entity>>
PetitteCigar <<@entity>>
but rather
Cigar <<@entity>> with all the attributes.

Question: How do I make sure that I've shown that these three important categories are supported by my design?
One solution that came to my mind - is to provide Object diagram along with my Class diagram and that on that Object diagram show these Categories

P.S.
I've read "Position on real assignment" I don't feel like my post reveal any solution details.

But how do you expect anyone to answer this without revealing solution details?
