You are the accountant working for a large brick-and-mortar flower store and your boss have recently started the project to take the store online. As the person who is most familiar with the accounting processes in the store, you are tasked with producing the UML Class Model showing the main functional entities and the cardinalities between them. You have compiled the following business rules:3 1. Each customer participates in a minimum of zero and a maximum of many sales. 2. The inventories are grouped into several categories. Some categories currently do not have any flowers. However, each flower type in the inventory must belong to only one category. 3. The purchase function sources the inventory from many potential suppliers; however, each purchase may also come from several suppliers. 4. For products that are temporarily out of stock, a "partner store" is contacted to fulfill that order. For special purchase like this, each purchase comes from only one partner. 5. Each purchase is handled by one and only one employee. 6. Each sale is also handled by one and only one employee. 7. The receipt documents the product purchased, the purchase order, the supplier or the partner that dealt with the purchase order, and the cash disbursement. 8. Each supplier participates in a minimum of zero and a maximum of many purchase orders. 9. Each sale involves a minimum of one and a maximum of many inventory items. 10. Each cash receipt (e.g., one check from a customer) is deposited into one and only one account, and each account is associated with a minimum of zero cash receipts and a maximum of many cash receipts. You need to do the following tasks: 1. Draw all the main functional entities for the Sales & Purchase model 2. Indicate their Cardinality.
