Design phase: System Design

Chapter 9

1. Develop an entity-relationship diagram (ERD) with cardinalities based on the procedures described in the narrative and the systems requirements (input, process, and output requirements) and DFDs (data flows to and from data stores) in your System Requirements Document.
   
   
   
   
   • Your ERD should be similar to the ERD in Figure 9-19 in TR11, that is, a single diagram using crow’s foot notation with no duplicate entities, all relationships labeled, and all cardinalities indicated, except that you should use MS Visio instead of Visible Analyst.
