| With the development of information technology and network technology, information system is widely applied to all industries. It is changing the way people work and lifestyles. The paper mainly introduces the research and achieve of an expert diagnostic medicine Daogou system. System which will be applied in the forefront of medicine industries is based on management information system. It can provide the first line of scientific help for the self-medication of patients, and enable enterprises' internal information to be shared and exchanged.The paper, combining topic's specific development and practice, conducted in-depth theoretical and practical research for the key technology of information system. First, on the foundation of the current information system development and use of C/S and B/S common pattern analysis and comparison, from the perspective of engineering practice, the paper explores and researches a new C/S and B/S mixed mode application of management information system. The development of the entire system applies life cycle and DAMA (demonstration and discussion). Database model choices relations type database. Database is used to store enterprise drugs' information and knowledge. The expert system uses diagnostic-based expert systems, its main function is to help ordinary disease patients in the purchase of medicine to provide medical help. The shell of the expert system applies adopts self-development. The Reasoning process is forward reasoning process. The paper, in accordance with the general system development steps, specifically introduces the entire system development method, system design, database systems and the establishment of systems to achieve specific model. Finally, the paper explores the system to achieve key technology.The paper has the larger theoretical and practical significance for the rational choice model of management information system, reducing system development cycle, improving system resilience to different regulatoryrequirements, and enhancing the flexibility and security of the system. At the same time, the paper applies expert system in the management information system to make the information system have intelligent features. It has a certain reference value for the combinational application of the management information system and artificial intelligence technology in the practice. The topic takes practical application as its purpose. In the current, the system has basically established. The system testing shows that it has gotten the specific requirement of the practical application, and has better results. |
