摘要 在引入粗糙关系数据库(Rough Relational Database,RRDB)的基本概念基础上,分析得出粗糙关系数据库中使用的几个主要数学理论包括等价关系、分解、位模式、粗糙熵及粗糙集理论,并进一步深入研究了这些理论在RRDB中的相关性质,对它们在粗糙关系数据库中的应用进行了探讨。 The fundamental concept of rough relational database is introduced in this paper, some prime mathematics theories including equivalence relation, decomposition theory, bit pattern, rough entropy and rough set used in the study of rough relational database are investigated in detail, moreover some conclusions about these theories related on rough relational database are obtained, and their applications are discussed too.
