| Abstract | Extended Entity Relationship Modeling is an accepted standard method used during the analysis and design phases of system construction. It encompasses two activities. First, the methodology is used to create a semantic, or conceptual, model that provides an accurate representation of the information requirements necessary to satisfy a particular application arena. Then, second, the finalized model, which is composed of a conceptual diagram and supplemental data, is transformed into an initial logical relational database design that represents the meaning of the original model in a form compatible with, and understood by, the Relational Database Management System. Relationship Modeling approach, including both the specification of a conceptual model and its associated database design derivation process. Design issues raised by the use of the Extended Entity Relationship Modeling technique are also examined. My intent, then, is to demonstrate the effectiveness of the basic technique. First, I show how the technique can be used to create an effective conceptual representation of a target domain. Second, I demonstrate how the completeness, flexibility and ease of understanding and use of the initial conceptual model can be preserved and transferred to the logical design. And, finally, I explore |
