Structuring System Process

1. Explain why data flow diagramming can be correctly thought of a process of “functional decomposition.”
2. State an accurate guideline for an analyst performing data flow diagramming on knowing when no additional levels diagramming are needed. In other words, what is an accurate “stopping rule”?
3. Explain the nature of the relationship between information requirements determination (IRD) and data flow diagramming.In other words, how does data flow diagramming complement other IRD techniques?

PS;

Plz write this 3 questions in 2-3 pages, plus 2-3 references.

All the content should be related to the text book Ch7, which i put it in the attachment.

On the other hand, functional decomposition is the process of breaking…
