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.
