Design And Development Of Hospital Information System

Hospital information system (HIS) is fundamental equipment and technical supporting environments in modern hospital. HIS is not only tracing and managing the information produced by human being flow, financial flow and material flow to enhance the system working efficiency, but also supporting all medicine, education and research activity which serviced by medical recording of patients. It's a very important choice to build HIS to make hospital manage modernization and to be suited to the international way.As a system modeling language, UML express the analysis and design process of HIS. It use object-oriented system analysis and design method, namely driven by use case and development process of iterative and increment. Each development cycle of iterative include several phase making up of analysis, design and building. The system model was described by various visual models from many aspects in each phase. Obviously, I used all kinds of visual models of UML to design unified system model. In the basis of system offer-demand analysis, analyzing the question field, drawing out the use case diagram, objecting class diagram and dynamic behavior diagram, deployment diagram and component diagram. In the end, I provided a whole software system solution.In this research, I used the integrated development environment of Delphi as client-side development tool, PowerDesigner as database modeling tool, SQL Server as DBMS which worked on server. Obviously, I also used unified modeling language as system modeling description tool.In the end, some suggestion and solution in building HIS were gave.
