Develop a data model of Fred’s Train Shop’s expenditure cycle activities related to the acquisition of office equipment and other fixed assets. Fred sometimes orders multiple pieces of equipment. Vendors usually ship the entire order, but sometimes are out of stock of some items. In such cases, they immediately ship to Fred what they have in stock, and then send a second shipment when they obtain the other items. Conversely, several orders placed within a short time period with the same vendor might be filled with one delivery. Assume that Fred makes installment payments for most fixed-asset acquisitions, but occasionally pays for some equipment in full at the time of purchase.
Draw an REA Diagram of your data model. Be sure to include cardinalities.
