Data Flow Diagram Assignment

Draw a Context Diagram and a Diagram 0 Data Flow Diagram for a business situation that you are familiar with. You need to give me a written explanation of the situation so I can look at your diagram with some background. For at least one process in the Diagram 0, create a Diagram 1 that gives the detail.
If you really can't think of anything to do contact me about doing one of the case studies in the textbook instead.
