Abstract
Expert system is a branch of artificial intelligence, its development speed is very fast, the application of expert system already permeate ,such numerous fields as physics , chemistry , medical science ,etc.. Almost all the expert systems can bring people's efficiency up to about 10 times at least.
This system utilizes PowerBuilder 9.0 according to the theory knowledge of artificial intelligence and expert system. The purpose of the system is to realize the diagnosis and treatment of diabetes in order to utilize computer simulation human expert.
The paper introduce the principle and structure of expert system , It explained the design of knowledge base, reasoning machine , database , interactive interface, explaining device and implementation method in detail. During the development the expert system I use all I have learnt to make the system run correctly and eccectively.
Key word: Expert system, the database , PowerBuilder, artificial intelligence
