Draw the ER diagram for the following problem. 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.
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. Remember to include subtype discriminator.
