the relational database standardization design requirements for handling process to eliminate data redundancy and update anomalies. Fan Shihua theory of algorithms and data dependence has a direct connection, relying on data dependence is the most important thing in function, and identify the dependence is both time-consuming and complex. This article discusses how to in the ER model database logic design step eliminate standardization process, in the process of conceptual structure design to follow a set of rules will lead to meet the initial relationship model set of 3 nf paradigm, to save the database designer after initial relational schema set derived the standardization of the processing steps.
