关系型数据库在变电站仿真培训专家系统中的应用

The Application of Relationship Database in the Substation Simulative Training Expert System

知识库和数据库是专家系统重要的不可缺少的组成部分，其性能的优劣直接影响到软件的通用性和易操作性，也直接影响到用户对整个专家系统的评价。本文对利用关系型数据库表示和存储知识、信息的方法进行了分析研究，并以事故仿真部分为例探讨了关系型数据库在变电站仿真培训专家系统中的应用。

As the knowledge base and database are the essential and important parts of expert system,their functions can effect the operatability and universality of the system directly.They also have an influence on the user' appraisal.In the paper the methods of saving knowledge and data by using relationship database is analysed.Meanwhile,the author introduces the application of relationship database in the substation simulative training expert system with the example of simulative training in accidental state.
