Appendix C:Conceptual Design, Verification, Logical Design

Discussion Focus How is a database design verified, and why is such verification necessary? Use our detailed answer to question 1 to focus class discussion on database design verification. Stress that the verification process uses the initial ER model as a communication tool. The designer may begin the verification process by describing the organization's operations to its end users, basing the detailed description on the initial ER model. Next, explain how the operations will be supported by the database design. Stress that the design must support the end-user application views, outputs, and inputs. Points to be addressed include such questions as:  Is the description accurate? If not, what aspects of the description must be corrected?  Does the model support the end-user requirements? If not, what aspects of the end-user requirements have not been addressed or have been addressed inadequately?
