Task 2: Data Flow Diagrams (DFD)

Develop a context diagram and diagram 0 for the Food Ordering System described in the following narrative. If you discover that the narrative is incomplete, makeup reasonable explanations to complete the story and supply them along with your diagram.

Consider Slim Burger, a new fast-food restaurant at Zayed University Campus. Many students are convinced that its hamburgers are the best in Abu Dhabi. The restaurants owners recently decided to develop a Food Ordering System, with your help (as the system analyst expert!).

The system takes orders directly from customers (via kiosks), generate receipts for customers, sends the food order to the Kitchens Chef, monitors goods sold and inventory, and generate reports for the restaurant manager. If the customer pays by credit/debit card, the system will also send a cash withdrawal request to the bank.
