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. Using generalization,
develop an EER model segment to represent this situation
using the traditional EER notation, the Visio notation, or the
subtypes inside supertypes notation, as specified by your
instructor. Remember to include a subtype discriminator.
