- To eliminate the need for writing original programs
- To replace the functionality of preprogrammed code
- To understand, organize, and piece together preexisting code (correct)
- To automate the system design process
What is the main difference between logical and physical data flow diagrams (DFDs)?
What is the main difference between logical and physical data flow diagrams (DFDs)?
- Logical DFDs are used during analysis while physical DFDs are used during design
- Physical DFDs contain additional details describing how the system will be built (correct)
- Physical DFDs only include data flows and no processes
- Logical DFDs represent real-time system operations while physical DFDs represent batch processing
