Using Microsoft Visio, individually create the Event Data Flow Diagrams and a System Dataflow Diagram for the processes in the following restaurant scenario: P1 The chef orders supplies from a supplier and records it in a supply order. P2 When he receives the supplies, the chef checks the supply order and stores the goods in his ingredients cupboard. P3 The customer makes a reservation and the maitre d' checks and records it in a reservation list. P4 When the customer appears, the maitre d' consults the reservation list and seats the customer at a table. P5 The customer orders a meal using the menu and the waiter records it in a meal order. P6 The chef prepares the meal using the meal order and a recipe with the specified ingredients, stores it on the meal counter and notifies the waiter. P7 The waiter takes the meal from the meal counter and serves it to the customer. P8 The customer pays for the meal using his/her credit card. The credit card company authorizes credit and the waiter receives payment.

A process must always separate an agent from another agent, data store from another data store, and an agent from a data store. The diagram must include all the processes, agents, data stores, and data flows necessary to complete the scenario.
