中文摘要: 关系数据库设计要求规范化处理的过程以消除数据冗余和更新异常问题. 范式化理论的算法与数据依赖有着直接的联系, 数据依赖中最重要的是函数依赖, 识别该依赖既耗时又复杂. 讨论如何在采用ER模型的数据库逻辑设计步骤中消除规范化处理过程, 在概念结构设计过程中遵循一组规则将产生满足3NF范式的初始关系模式集, 以节省数据库设计者在导出初始关系模式集后的规范化处理步骤.
Abstract: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.
