What is the purpose of program design techniques despite the reliance on preprogrammed code?
- To eliminate the need for writing any original code
- To understand, organize, and piece together preexisting code (correct)
- To solely focus on logical DFDs for system design
- To minimize the importance of understanding preexisting code
What do logical DFDs for the to-be system primarily describe?
What do logical DFDs for the to-be system primarily describe?
- Physical process models during system design
- Processes and data flows needed to support functional requirements (correct)
- The need for packaged software or libraries
- Implementation details of the final system
What is the key difference between a logical DFD and a physical DFD?
