Development of distributed HIS architecture based on C/S structure / 医疗卫生装备

ABSTRACT

Objective To develop a HIS architecture based on.NET in C/S environment,so that the different functional modules of the HIS can be easily loaded into the architecture to improve the efficiency of HIS development and reduce development costs.Methods The proposed HIS architecture underwent hierarchical structure design,and was composed of boundary,logic,data access and physical layers.The user input data through the boundary layer,responded to the user request through the logic layer,and reacted to the request from the logic layer through the data access layer to realize database access.The boundary,logic and data access layers transferred data through the physical layer which was used as the data carrier.C# language of Visual Studio 2008 was applied to the development of the architecture program.Results The system could conveniently load each function module in HIS of the hospital,which greatly facilitated the developer to control the function of the program.Conclusion The system meets the requirements of medical staff and management to the software,improves the efficiency of HIS system development,and reduces the cost of system development.
