What is the purpose of program design techniques despite the reliance on preprogrammed code?
What is the purpose of program design techniques despite the reliance on preprogrammed code?
- 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
Why are program design techniques still important despite the reliance on packaged software or preprogrammed code?
Why are program design techniques still important despite the reliance on packaged software or preprogrammed code?
- Even preexisting code needs to be understood, organized, and pieced together (correct)
- Preprogrammed code eliminates the need for program design techniques
- Program design techniques are becoming obsolete
- Project teams no longer have to write any original code
