Data Flow Diagrams vs. Use Cases – Student Perceptions
Ido Millet, Robert H. Nelson · International Journal of Information and Communication Technology Education · 2007
Data flow diagrams (DFD) and Use Cases are two popular methodologies in teaching as well as in practice. We recently used both methodologies in teaching eight sections of a required systems analysis course. Questionnaire results indicate that students perceive these methodologies as equally easy to understand and use. Students believe that data flow diagrams are better at communicating with users and programmers.
