Give two examples of aggregation over-specification and two for aggregation


under-specification.



Use parameterized participation constraints to create the aggregation hierarchy


of a high rise building. The building has a certain number of floors, each having


two types of apartments, standard and luxury. In each floor from floor 4 and


above there are three standard and two luxury apartments. In the first three


floors, there is one small and two large offices. Decide how many floors there


are and how many faucets are required for each unit, and create the appropriate


OPD with participation constraints. Using your diagram, compute the number


of faucets the contractor needs to order.
