True
DFDs are only used for high-level system design.
False
Dependencies should be ignored in the diagramming process.
False
Diagramming is only necessary when there are no product changes.
False
What is the primary purpose of using Data Flow Diagrams?
To visualize the flow of data through a system
Why is it important to update diagrams as product changes occur?
To reflect changes in the system's data flow
What is the purpose of enumerating assumptions and dependencies in diagramming?
To clarify the relationships between system components
What is a key benefit of using Data Flow Diagrams in system design?
They clarify the relationships between system components
Why is it important to maintain accurate diagrams in system design?
To maintain a clear understanding of the system's data flow
Study Notes
Diagramming
- Use Data Flow Diagrams (DFDs) as a diagramming technique
- Update diagrams regularly as the product undergoes changes
- Identify and list assumptions made during the diagramming process
- Identify and list dependencies between components or processes
This quiz covers the basics of system modeling using Data Flow Diagrams (DFDs) and how to update diagrams to reflect changes in the product. It also tests your understanding of assumptions and dependencies.
