No assigned reading this time? Also, in the last example, should Durations be regular entities, or perhaps weak entities? Doesn't make much sense to have durations all by themselves without a reference to some relationship. So, shouldn't we use aggregation around the WorksIn relationship, and make them owners of the Durations entities?
