Your response must be at least two complete pages long (excluding cover page), using the APA writing style. You also must include at least one external reference and citation for each case problem. The reference and citation must be related to the material being presented, and cannot be the textbook or the case itself.Our Case Study 1 can be found on page 78 of our textbook (Case 3-1 “Dub 5”). This case builds on material presented in the Chapters 1 and 2, combined with the discussion about systems documentation techniques in Chapter 3 (especially, Data Flow Diagrams or DFD).As you prepare to complete the case, in addition to reading chapters 1-2, read also the DFD discussion on pages 50-54, which begins our reading assignment for week 2.I suggest that you organize your Case Study as follows:1) Summary of the Case What is the purpose of the case? For example, in this case, provide a DFD view of the order and credit review process for DUB 5.2) Level 0 DFD for Order processingUsing the written description of the DUB 5 process in the case, and the rough diagram at the bottom of the case, create your Level 0 DFD. You can submit a DFD that is hand-drawn and scanned, use Excel or Visio, or another program.3) Level 1 DFD for the Credit Review ProcessGoing down one level in the DFD, focus on the credit review process only and create a DFD for this process. Again, you can submit a hand-drawn DFD or use an automated program.
