Creating Data Flow Diagrams

A local restaurant is planning to implement an online ordering system. The first step in their project is to map out the order process and what information needs to be input and output from an order.

Using an application of your choice (MS Word, Visio, Draw.io or any other open source tool), create the DFD Level 0 or Context Diagram of a restaurant ordering system.

After completing your context diagram, select one of the processes, then identify the items which make up the four data flow diagram elements:

(1) Data sources and destinations

(2) Data flows

(3) Transformation processes

(4) Data stores

With the above information, complete a level 1 detailed diagram for the selected process (use the previously selected software).
