Research Of HIS Application Framework Based On The Plug-in Technology

HIS has a clear advantage of module, platform compact, but it is weak in the integration of software reuse, and difficult to cope with the diversities of the data sources, the extension of the development trend of HIS function etc. In this dissertation, combined with the advanced technology of plug-in software development mode, the dynamic expansion with a kind of HIS application framework is exploredBased on HIS application as the starting point, Firstly, this thesis introduces the relevant concepts, the features, the advantages, the history and the main technologies. And then the thesis focuses on the structure and theory of plug-in architecture, and analyses designing thoughts and developing principles. Thirdly, based on object-oriented technology, the plug-in classified system of basic functional layer Model, advanced functional layer Model, Expansion functional layer Model and the object model are constructed, in this model, structural definition, formal description, interface design and the core plug-in module design are carried. Based on the different levels plug-ins, standard expression of the different levels plug-in is constructed. At last, the thesis gives a practical project to verify the feasibility of the proposal.Through the research in the dissertation, a plug-in application frameworks of the HIS system is achieved, the complexity of HIS integration application system is simplified. The ease of use, scalability and feasibility are enhanced. It provides new methods and ideas to achieve dynamic load, flexible configuration, expansion of convenient, easy to deploy and highly reusable HIS applications.
