DFDs (Data Flow Diagrams)

The PPI website project is focusing on creating and documenting data flow diagrams (DFDs). Suzanne feels that this traditional approach is a proven way of building a strong foundation for the analysis and design work that lies ahead. Charlie is not so sure. He spent last week identifying requirements and creating some high-level use cases. He is anxious to continue with the object-oriented techniques. During lunch, Charlie tells Suzanne that he doesn’t understand how the DFDs will help in building the PPI project. Read the PPI (file uploaded). 1. If you were Suzanne, how would you respond to Charlie? Describe how DFDs will help in building the PPI project. 2. Discuss the strengths and weaknesses of the traditional approach using DFDs to systems development. Answer in your own words & in paragraph form. Read the Chapter B (file uploaded). Follow the APA Guidelines (file uploaded). Do not write introduction & conclusion. You can add additional sentences/paragraphs. You can research on the Internet or books/journals & you can add additional references.
