The IT team at Game Technology is moving forward with the new Customer Contact Care information system, or C 3 . 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 C 3 system will have three external entities, with the following data flows:
| Entity | Data Flow from the Entity | Data Flow to the Entity |
| Customer | Contact Information | Sales Specials |
| Sales Records | System Customer Sales History | None |
| Marketing Rep | Suggested Contact Plan | Sales Feedback |
The C 3 system also will have three processes (Analyze Customer Data, Analyze Sales History, and Manage Contact Plan), a data store (Customer Profile), and the following data flows:
|
Data Flow |

| Customer Data (two-way) | Customer Profile data store | Analyze Customer Data process |

Challenge Tasks
Your context diagram and DFD diagram 0 were accurate, but there have been some design changes. Management has decided to connect the external Accounts Receivable System directly to the C 3 system as a fourth entity. A two-way data flow called AR Data will connect this entity to the C 3 system. Inside the C 3 system, AR Data will connect to the Analyze Sales History Critical Thinking Challenge: Tasks Page 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.
Task 1. Draw a context diagram for the new C3 system that shows the revised design.
Task 2. Draw a DFD diagram 0 that shows the revised design.
