1. Create a context diagram for the Reliable Pharmaceutical case based on the system description in Chapter 1 and the event table that you developed in Chapter 5.
2. Create DFD fragments for each event from the event table and ERD that you developed in Chapter 5.
3. Create an event-partitioned model (diagram 0) by combining the DFD fragments you created for question 2.
4. Create a logical DFD showing the processing details for the event Time to generate orders (shipments) based on the description in Chapter 1. Pay careful attention to modeling data movement and processing, not the movement and processing of physical goods (for example, drugs). Create any process descriptions and data definitions needed to fully specify system requirements.
5. Consider the problem of modeling the billing procedures briefly described in Chapter 1. Should a physical DFD of billing procedures be developed? Why, or why not?
