Information Management System Based On COM+ For Clinic Doctors' Workstation

With the phenomenal progress of science and technology, hospital Information System(HIS) have been a important method to manage hospital scientific and raise medical service. My treatise researches the present development of the HIS and software. After that, I gives the solution project of Windows DNA which is based on the system structure of three layers , and then I adopts the program devise which is based on the component of COM to direct the System's exploitation. That should build an application system with good dependence and expansibility .In the procession of establishing clinic service doctor in workstation information management system, I collects and arranges massively about components, COM, and COM+. Through the thorough analysis, I have grasped the elementary knowledge and I can establish this system. I have formed the knowledge system which could lay the solid foundation for the next step of system's design and realization.The computer knowledge which concerning to establish this management system is mainly :the distributional system;Three layers computations patterns (user service layer, intermediate level and data service level), this kind of three layers computations pattern has solved many malpractices of beforehand two layers computations pattern, the intermediate level is about two links, it establishes the actual database connection.This management system is based on Windows DNA three layers systems structure and the COM component procedure solution. Therefore I must study...
