Further detail on the relationship between top-down (specialization) and bottom-up (generalization) EER modeling and our expectations regarding EER model constraints
Id love to use your videos to study but could you pleasssseeee put them all in a playlist that starts with the first introduction video proceeding to the last. Its all over the shop and I dont know where to start
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.
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.
