REA MODEL-HORIZON BOOKS
Horizon Books is a bookstore in downtown Philadelphia. It carries an inventory of approximately 5,000 books. Customers come in and browse the shelves, select their books, and take them to the cashier. At the cashier's desk, they can also discover whether a particular book is in stock, place orders for books not currently available in the bookstore, and collect and pay for books previously ordered. There are no credit sales. All customers pay for their purchases at the time of purchase.
Required
Prepare an REA model for Horizon's database. Show all cardinalities in the associations.
