Questions and Answers

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)?

  • 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?

  • 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
