Draw the context diagram and level-0 DFD to model the process described below. If you feel the narrative is incomplete, make some reasonable assumptions to complete the story. It is important that you supply these assumptions along with the diagram. A farmers cooperative buys agricultural supplies from large distributors in bulk to get volume discounts and then sells these supplies to farmers at cost. Farmers need to be a member of the cooperative to be eligible to purchase supplies at discounted prices. Every December, farmers send their request to the cooperative regarding their needs for supplies for the next year. The cooperative consolidates these requirements and then contacts distributors with information about quantities needed of various supplies. Distributors respond by sending their price quotes and their estimated delivery dates. Acceptable prices and delivery dates information is passed to farmers. Farmers then send their confirmed requirements to the cooperative. The cooperative uses membership database to check to make sure that their membership is current. If it is, it sends them a confirmation, otherwise it sends them a note requesting them to renew membership. All of the demand information is consolidated by the cooperative and an order sent to the distributors for fulfilment. The order information is stored in the order database and also sent to the external relationship department of the cooperative

Fancy Inc. is a worldwide clothing and accessories retailer. It appeals to particular segments of customers, who tend to be loyal to it. Customers send in their product orders to Fancy Inc. A receiving clerk receives the orders and checks the inventory positions of all the products in the order. If all the products are in the inventory, the receiving clerk sends the product order to the fulfillment department. The fulfillment department fulfils the order, updates the inventory and accounts receivable files and sends a notification of completed order and an invoice to the customer. If none of the products is available, the receiving clerk sends an apology note to the customer and offers a 5% rebate for the next order. If some products are available and others are not, the receiving clerk sends the order to an expeditor. The expeditor arranges for the unavailable products to be shipped to the fulfillment department. Once all the products are available, the fulfillment department follows the exact same procedure as explained earlier. Draw the context and level-0 diagram for this business situation. Make your assumptions explicit.
