Practice Exam Part 3 [p.3.15] domain modelling: Why is class diagram the least useful for domain modelling? #552

This is the answer: image

However, in the textbook, it mentions that class diagrams can be used to model the problem domain as well: image

The way I interpreted it is since class diagrams can be OODMs, shouldn't it be useful for domain modelling? This makes the other options less useful for domain modelling.

@garylow2001 I agree that this question is a bit confusing. Would have been clearer is OODM was one of the options. The way the textbook is worded also adds to the confusion. I've made a note to reword it in the next version.

This question tests two learning points:

  1. Any model (not just UML models) can be used for domain modelling
  2. Class diagrams are not used for domain modelling because there is a more optimized model we can use for the same purpose i.e., OODM

I understand, thank you!
