| 摘 要： | 利用粒计算方法对粗糙关系数据库（Rough Relational Database，RRDB）的粗糙函数依赖进行研究。首先提出了两种类型的粗糙函数依赖及粗糙相似关系的概念，分析了如何利用位模式表示粗糙关系的属性值，在此基础上给出了利用粒计算方法对粗糙关系的属性间的依赖关系的进行判定的算法，实验验证算法是有效可行的。

| Abstract: | The rough functional dependencies are discussed based on granular computing in this paper.Two kinds of rough functional dependencies and rough similar relations are proposed firstly,moreover the representation of attribute values of rough relations are analyzed.Finally,an algorithm for judging rough functional dependencies in RRDB is presented,an example is illustrated and results show that the proposed algorithm is useful and effective. |
