Answers to Review Questions
CHAPTER 8 Requirements
1. What is the advantage of a DFD over other diagrams?
The data flow through the system and the specific data that is available to each process
are clearly shown.
2. What is the purpose of behavior specifications and diagrams in requirement specifications?
The purpose is to communicate an overview of the proposed system to the user to
ensure mutual understanding of the overall behavior of the proposed system.
