An object-oriented methodology for end-user logical database design: the structured entity model approach

A well-designed database that contains relevant, nonredundant, and consistent data is rarely achieved in practice. One major reason for this is seen to be the lack of effective support for logical database design. In view of this, the structured entity model (SEM) method, an object-oriented method which facilitates the logical design phases of database system development was developed. Because, unlike most methods, SEM does not require designers to understand normalization theory in order to design a logical database, an end user (or a novice designer) can successfully complete logical database design using the method.<>
