Draw an ERD containing the Order and Customer entity types connected by 1-M relationship from Customer to Order. Choose an appropriate relationship name using your common knowledge of intersection between customers and orders. Define minimum cardinalities so that an order is optional for customer and a customer is mandatory for an order. For the Customer entity type, add attributes CustNo(primary key), CustFirstName, CustLastName, CustStreet, CustCity, CustState, CustZip, and CustBal (balance). For the Order entity type, OrdCity, OrdState and OrdZip.
