Abstract: The ES capacity is influenced by the abundance of knowledge, the storage and management of the knowledge base determine the ES reasoning efficiency to a great extend. In this paper, The knowledge base design of dam safety monitoring expert system based on RDB is discussed in detail. With thus knowledge base, the knowledge of ES is extendable and reasonable, and the ES has more intelligence and solves the issue more effectively.?

摘要： 知识库是整个专家系统的灵魂，知识库中知识的表达、组织与存储模式将影响推理机的推理效率，同时也会影响知识的更新与丰富，最终影响整个专家系统的智能水平。本文着重论述了用关系数据库来设计大坝安全监控专家系统知识库的方法，使知识库具有较好的知识扩展性和合理性，使专家系统的智能水平可以得到不断的提升。同时，利用关系数据库实体间的关系，很容易维护和使用存储在其间的知识，使整个专家系统具有较高效的推理效率。
