摘　　要：对粗糙关系数据库(rough relational database,RRDB)在国内外的发展状况进行了探讨。具体分为两部分,其一,对于与粗糙关系数据库相关的几个概念及它们之间的关系进行了研究;其二,从多值信息系统的规则生成及属性约简、RRDB的粗糙算子研究、RRDB的数据查询及数据更新、RRDB的度量研究及粗糙函数依赖等几方面对目前粗糙关系数据库在国内外的发展状况进行了总结回顾。The rough relational database and its development were discussed in this paper. Concretely, some basic concepts related to rough relational database and their relationships were analyzed, and then the development status about rough relational database were reviewed from the rule generating and attributes reducing of non-deterministic information systems, the rough operators, the rough data querying and updating, the measures study and the rough functional dependencies.
