Background

The IT team at Game Technology is moving forward with the new Customer Contact Care information system, or C3. Your next assignment is to develop a set of data flow diagrams (DFDs). To be sure you can handle the tasks, you decide to review Chapter 5 of your systems analysis textbook. Based on your requirements model, you know that the new C3 system will have three external entities, with the following data flows:

Task 1: Draw a context diagram for the new C3 system.

Task 2: Draw a DFD diagram 0 that shows the three processes, the data store, and the data flows.

Task 3: Management has decided to make some changes and connect the external Accounts Receivable System directly to the C3 system as a fourth entity. A two-way data flow called AR Data will connect this entity to the C3 system. Inside the C3system, AR Data will connect to the Analyze Sales History process. Also, another new two-way data flow called Billing Data will connect to the Analyze Sales History process and the Customer Profile data store.
