Arnold's Corner Store ERD Modeling Case (10 points) Arnold has a corner grocery store. His store is a great place for the local neighbors to shop for their favorite foods and basic essentials. He carries produce, pre-packaged food, and fresh deli and bakery items. He also carries important paper goods and cleaning supplies such as napkins, dish soap, and paper towels. As a small store, Arnold likes to get to know his customers. He records the customer's name, email address, and date they first visited the store. On the anniversary of their first visit, customers receive a coupon for a free bakery item. He has a point of sale (POS) system that captures check out transactions for every purchase made. After items are checked out and the customer has paid, the POS will print a receipt for the sale that lists all items purchased. A different receipt is printed for each purchase made, even if the customer returns later in the day to make another purchase. The receipt should print a thank you note using the customer's first name at the bottom.
