thanks for your emphasis on each explanation. like in the disjoint and overlapping examples and contrasts. you explained the design choices fro choosing disjoint and overlap more than I could hope for.

Not quite. A second line from people to the circle would mean that each person in the domain MUST participate in a specialization category. In other words, each person is required to be either an employee or a student or an alum. Whatever the participation constraint, you should elicit and model whatever specialties are useful. If you needed to add additional categories beyond student, employee and alum, you should do so, no matter what the constraints.

So a second line from People down to the cirkle would indicate that there could be more categories than those three? (Nice video!)

What are the differences between ER and EER?
@flipsmash8 жыл бұрын
+Ralph Ng EER includes the generalization/specialization relationship, thus extending the original ER model, which did not include it.
