Question
Design a graphical user interface based on a given scenario
The design process usually involves 5 types of design effort modules (outlined in this week’s textbook reading). Let’s discuss a business case from the perspective of these design modules. Let’s review process modeling below:
1. What is a process model? What is a data flow diagram (DFD)? Are the two related? If so, how?
2. Distinguish between logical process models and physical process models.
3. Define what is meant by a process in a process model. How should a process be named? What information about a process should be stored in the CASE repository?
4. Define what is meant by a data flow in a process model. How should a data flow be named? What information about a data flow should be stored in the CASE repository?
5. Define what is meant by a data store in a process model. How should a data store be named? What information about a data store should be stored in the CASE repository?
6. Define what is meant by an external entity in a process model. How should an external entity be named? What information about an external entity should be stored in the CASE repository?
