ABC Company Sales System ABC Company sells goods online. When a customer places an order, the system checks to see if the item is in stock and then issues a status message to the customer. The system then stores the order details until it generates a shipping order which is sent to the Warehouse. Once the Warehouse has shipped the order directly to the customer it sends a confirmation to the system which then produces an invoice for the goods to be sent to the customer. Once the customer pays the invoice the account details are updated to reflect the current account balance. Each week the system prepares reports of orders and accounts for the manager Your tasks: 1) Draw a Context diagram below for the "ABC Company Sales System". 2) Draw a diagram O level DFD below for the "ABC Company Sales System". which incorporates only the functionality included in the case study.
