To identify the essential object s components added in EERD 2. To define constraints on specialization /generalization 3. To illustrate specialization /generalization constraints. 4. To develop a complete conceptual design with EERD ACTIVITY Draw the EER diagrams for the following problems using UML no tation, Crow’s Foot notation and Chen notation: 1. A bank has three types of accounts: checking, savings and loan. Following are the attributes for each type of account: CHECKING: Acct No, Date Opened, Balance, Service Charge SAVINGS: Acct No, Date Opened, Balance, Interest Rate LOAN: Acct No, Date Opened, Balance, Interest Rate, Payment Assume that each bank account must be a member of exactly one of these subtypes. Develop an EER model segment to represent this situation using the UML, Crow’s Foot and Che n notation. Remember to include the subtype discriminator. 2. A nonprofit organization depends on a number of different types of persons for its successful operation.
