Research And Implement Of History Information System Based On UML And Software Reuse

It's known that Information technology and Life science is the markedknowledge in the 21st century. And information, network and advanced technologyis the basic feature of the social development. It's the requirement of hospitalscientific management and the necessary way to link with international field. Withthe fast change of hospital management mode, a large requirement of the relatedinformation data will appear. It is an important choice to construct hospitalinformation system to make hospital management digital and modern. Hospitalinformation system will enhance medical service quality, working efficiency andeconomical benefit in order to increase competition advancement and meet the needof hospital innovation.Object oriented modeling language based on Unified Modeling Language(UML) has been one of the most welcome methods in the present software modeling.UML is a kind of modeling language which is fine defined, easy to express andpowerful in function. It adopts the new conception, method and technology insoftware engineer. It's also a trend to apply UML to the development of informationsystem. Software reuse is used to construct new system by using of the existedsoftware components which can be reused. It's thought that software reuse is a mainway to solve the software crisis, enhance efficiency, quality and advance theopenness and adjustability of software.At first, this paper analyzes the development, essentiality and importantmeaning of HIS. And then it introduces the development history, research actualityand related conception of UML and Software reuse. On the base of the wholeframework of HIS of Hubei Zhongyi Hospital, it analyzes the need of functionaloffice subsystem in detailed, one of the most important part of HIS. Then it gives therealization process of modeling by drawing out the usecase diagram, sequencediagram, collaboration diagram, statechart diagram and activity diagram of thesubsystem. With the help of constructing the database model and developing thewhole HIS, the paper has achieved an integrated process of software development and showed a value both in research and economy. At the end of this paper, it givesus some advice and resolvent according to the existed problem in actual HIS,...
