【摘要】 为使关系数据库具有较好的知识表达能力,能够适应决策支持的需要,从管理信息系统的知识表示需求出发,讨论了通过触发器和SQL数据处理工具实现规则知识的数据化,从而形成引信与规则知识相互独立、强化关系数据库知识表示能力和知识管理能力的方法;论述了基于关系数据库设计的管理信息系统中知识表示的可行性.实践表明,在管理信息系统中内嵌知识表示从而形成管理信息系统的决策支持能力的方法能提高系统智能化水平.更多还原

【Abstract】 To increase the ability of knowledge presentation in relation data base to support decision-making,according to the knowledge representation demanding of in MIS,the study aims to digitize the knowledge by trigger and SQL in RDS.The fuse and knowledge are divided into trigger in this way,so the ability of knowledge representation and knowledge management will be strengthened.The feasibility of knowledge representation in MIS based on RDS is discussed.Obviously,it can enforce the intelligent level to insert the knowledge representation in MIS.更多还原
