Translate the brokerage into an SQL schema. Use the necessary SQL machinery to express all constraints speci?ed in the E-R model.
We will start with the diagram in Figure 4.30. In translating this E-R diagram, we choose to combine IsHandledBy with Account, WorksIn with Broker,and Office with ManagedBy. The rationale for these combinations is that in each case the entity type is a key role in the corresponding relationship. The reason why ManagedBy is combined with Office rather than Broker (which also happens to be a key role in the ManagedBy relationship) is that it is more likely for an o?ce to have a manager than it is for a broker to be a manager. Therefore, combining Office with ManagedBy into one table is unlikely to lead to many null values being stored with the Office table. In contrast, combining ManagedBy with Broker is likely to cause a situation where the value of the attribute Manages of the table Broker would be mostly NULL.
