Draw an EER diagram to represent the following situation: When appropriate, model an associative entity. A rental property would like to store information about TENANT, DEPENDENTS and Payment. The property would like to store information about Tenant: Unique Tenant Id, Tenant Name(first and last), Address(Street, City, State), Phonenumbers (country, Area, local), Email Address and House Type. A housetype can be a Townhouse, Apartment or Individual house. For a Apartment, we will store Unique Apart number, number of rooms; for an Individual house, we will store Unique House number, size of house. We will not store any additional information about Townhouse. Dependents are depended on the tenants. Dependent can be uniquely identified by their name. For PAYMENTS, the following information will be stored: a unique payment id, the Bank name associated with the form of payment used, and the account holder name. There are three different types of PAYMENTS: Card Payment, Cheque Payment, Bank Account Payment. If it is a card payment, then the unique card number and the expiration date need to be stored. If it is a bank account payment, then the unique account number and the routing number need to be stored. If it is a Cheque Payment, then the unique cheque Id and bank name. A tenant can use different methods of payment to pay the rental property. For example; the tenant can split $1000 payment using two methods; $500 paid in check and $500 can be paid by a card" Each Tenant must make at least one PAYMENT. Each PAYMENT will be made by exactly one Tenant. For each tenant, there may or may not be any dependents. Each Dependent belongs to exactly one Tenant.
