Design an ERD consisting of the Order and Customer entity types connected by 1-M relationship from the Customer to Order. Select the suitable relationship name utilizing your common knowledge of the intersection between customers and orders. Describe minimum cardinalities so that an order is optional for the 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.
