Research Of Hospital Outpatient-department Information System Based On Component Technologies

With the fast development of information technology industry, the building of hospital information has been developed greatly, and hospital information system based on information of economy and management has been built basically, but the development of hospital information began so late that it has great prospect. The general purpose of hospital information system is building medical information system based on managing diagnosis information of the patients.This topic develops HIS based on component technology under the background of The second XiangYa hospital. It uses the object-oriented idea, chooses objects by UML and MS SQL Server 2000 as backstage database, and finishes an operational design of HIS based on component technology.This paper studies component technology, software system structure, UML and the related theories, it also discusses software development method in the background of HIS. Later, it analyzes the present demand of the hospital, gets corresponding user demands, function demands and data chart, and puts forwards three-layers system structure based on component. It designs some modules: the register working station, the doctor working station, the charging station, pharmacy working station, and managing working station of the outpatient department in detail, and finally gets the working flow of system, the system function structure design drawing of each function module. In addition, it realizes the design bases on database of MS SQL Server, and introduced the key technology in system research in detail including: UML technology, J2EE technology, and so on; still it presents design realization of patient information inquiring component.The research of hospital outpatient information system based on component technology enhances the versatility, reuse, maintainability, and has made the preliminary attempt on research and development of software engineering, transformation from traditional software development mode to the new mode based on component technology.
