$2.$ Indicate the changes $($using the shorthand representation$)$ that you would need to make to the original TAL Distributors database design to support the following requirements. There is no relationship between customers and sales reps. When a customer places an order, any sales rep can process the order. On the order, you need to identify both the customer placing the order and the sales rep responsible for the order. Draw an E$-$R diagram for the new design.
