Questions and Answers

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?

  • 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?

  • Logical DFD focuses on packaged software or libraries
  • Logical DFD includes implementation details of the final system
  • Physical DFD contains additional details describing how the system will be built (correct)
  • Physical DFD solely contains data flows
