Chapter 10. A Worked Example for Data Flow Model Diagrams – Part 2
In the previous chapter, we listed the potential rules for the Gane and Sarson data flow diagrams, then we enhanced the masters in the Microsoft supplied Data Flow Model Diagram template. We also created a report to list the four DFD shapes, showing their unique values in the User.UMLShapeType
cell.
In this chapter, we will go through each of the 12 rules in detail, and write a rule to enable us to validate the diagram for each one.
