Along with the new type of rural cooperative medical system development, The expansion of system and business volume increase, The traditional manual mode of operation has been unable to meet the current demand. At present, most of medical insurance system adopt the C/S architecture in Shangyu, The information system development and the follow-up maintenance work are difficult, Because the client integrates business logic and user interface, the business logic of mutability leads the client programs to change frequently, and the rural cooperative medical care system needs to be adjusted according to actual situation due to the large volume and flexible business, it is imperative to establish an extensible medical information system.According to the new rural cooperative medical care policy in china and the actual situation of China’s new rural cooperation medical system operation, the main content of this paper is about developing a three layer structure’s new rural cooperative medical management information system with UML modeling tool power design, which has a layer of low coupling, high cohesion within the layer’s, characteristic of high safety, high efficiency, good expansibility and easy to maintain. Further extension of three layer distributed C/S mode architecture, using hierarchical thinking and component technology. Three layer logic architecture technology makes the coupling between the business logic and user interface reduced, so it is not difficult to make the software extension.This paper analyzes the research status of new rural cooperation medical insurance system at home and abroad, and put forward the necessity to build a new type of rural cooperative medical insurance information system. During the system development process, Firstly this paper has an analysis of the system according to the overall business demand.Then this paper describes the three layer structure of the overall system design and detailed design by Power design modeling tool. And finally this paper introduces the realization of the system main function, which is using Delphi V7.0combined and the SQL Server2005.The new rural cooperative medical information management system, which uses the three layer architecture, covers system settings, policy parameters, ginseng add up to personnel, compensation and settlement, audit management, record for approval, fund management and statistics inquiry. Compensation and settlement is the core function and it includes compensation settlement, compensation impact is, operator daily, collect daily, personnel information, catalog of medicines, medical directory, disease directory enquiries, parameter setting, operator permissions, compensation mechanism functions such as authority.Facts have proved that medical information system based on the three layer distributed C/S model, has advantages of strong security, reliability, flexibility, extensibility and maintainability etc., It meets the requirements of large amount of hospital information, information security and confidentiality, information sharing and high operating strong real-time. It reduces system upgrade and maintenance cost, improves the office efficiency, normative data processing, increases credibility of the government, facilitates the broad masses of people, achieves new rural cooperation, also. Medical services with efficient, accurate, and fast management help improvement of Shangyu new rural cooperative medical management. |
