The loan office in a bank receives from various parties request to investigate the credit status of a customer. Each credit request is identified by the Request ID and is described by a Request Date and Requesting Party Name. The loan office also received results of credit checks. A credit check is indentified by a Credit Check ID and is described by the Credit Check Date and the Credit Rating. The loan office matches credit request with credit check results. A credit request may be recorded before its results arrive; a particular credit result may be used in support of several credit requests. Draw an ERD for this situation. Now, assume that credit results may not be reused for multiple credit requests. Redraw the ERD for this new situation using two entity types, and the redraw it again using one entity type. Which of these two versions do you prefer and why?
