基于数据库技术的气流干燥专家系统知识库的建立

针对专家系统中传统知识表示存在的数据修改比较困难．数据与程序之间缺乏独立性，满足不了多用户、多应用共享知识需求的缺陷，故在闪速熔炼气流干燥专家系统中采用数据库技术来实现知识库，提出了基于数据库的知识表示方式，设计了规则库的数据库结构和类结构，然后利用ADO技术实现了对数据库的添加、更新等功能，并应用于知识库，从而可不断地扩充知识库，体现了知识库的健壮性，有益于知识库维护的一致性和完整性。

Establishing of Expert System for Pneumatic Drying Process Based on Database Technology

Aiming at problems such as difficulties of modifying data,lack of independent character between data and program,satisfied defects of multi-user and multi-application in traditional knowledge representation in expert system, this paper adopts database technology to achieve knowledge base. It brings up the knowledge representation based on database, designs the database and class structure of the rule base. The functions of adding,updating are achieved by using ADO. The application in knowledge base of expert system is successful which shows the robust of the knowledge base,and it is good for the consistence and completeness of the maintenance.
