摘要： 关系数据库的范式设计可有效地解决数据库的异常操作问题,在MIS的开发中有着重要的方法论意义。但是,由于其理论深度和复杂性,在实际工作中,它的应用受到限制。本文介绍的范式设计支持系统(FDSS)能帮助开发者越过上述障碍,支持用户设计出具有期望级别的数据库范式。

Abstract: The problem of operating error of RDB can be solved by the design of RDB normal form, which is a meaningful method in developing MIS. But its function is limited because of the complexity of the method. FDSS (Support System for the Design of RDB Normal Form) introduced in this paper can lower the complexity and help us to design RDB normal forms with expected class.
