| This thesis' project came from the clinic's development program of the medical management system of Inner Mongolia Electronic Information Vocational Technical College. Through the design and implementation of medical management system, the thesis analyzes a kind of applied website design scheme based on J2EE and mainly discusses the computer architecture of web application, Struts frameworks,component technology, multi-layer design technology and so on.The computer architecture of web application was briefly discussed , and the popular technology of .NET and J2EE was also compared and analysed to make sure that it is feasible to take J2EE as the design architecture of the system. Besides,the advantages of J2EE and its key techniques are described in detail.Based upon B/S architecture,the system is developed by MVC model based on Struts frameworks. The system is a multi-layer architecture:the layer of web,mainly through Servlet and JSP technology, makes programs of Web components at server-side and coordinates the data transfer among itself ,client and the layer of transaction; the layer of transaction, mainly through JavaBean, implements more complicated transaction logic and database storage ; the layer of data, is to access data from the database which is mainly through JDBC. The system is developed with the tools of Eclipse 3.4 and deployed on the Tomcat 6.0,while the database server adopts SQL Server 2000.On the basis of demand analysis,the thesis shows the basic functions of medical management system. The system fulfills the design and implementation of main functional module including staff information management,drugs management, treatment management, students' medicaid management, physical examination management and system management,which basically meets the needs practical work of the clinic. It also gives expression to some good ideas such as cross-platform, easily-maintenance, easily-expandedness and component-based design. |
