Design And Implementation Of Long-distance Medical Information System Based On XML And .NET

Using new management information system and software development platform to manage information has become a development trend of the Medical information system, with the rapid development of computer network. The majority of system is still in using of ASP or ASP.NET to produces the dynamic Web page and making a simple connection with the backstage database, in information system that using traditional technology to develop. However like this, traditional system far failed to meet the needs of users. Therefore, the research of high performance long-distance medical system emerges as the times require.After finishing the requirement analysis of long-distance medical information system and Comparing with several kind of realizations technology that are more popular in present, this paper describes the implementation procedure of a long-distance medical information system that based on .NET and XML technology. The paper introduces predominance and composing of .NET framework, explains ASP.NET technology, disscusses the storage and transformation of XML documents data, and describes a new generation of data access model that named ADO.NET in detail. The paper also studies the detail of interrelated technical in-depth, and establish design proposal of system. The system relies on SQL Server database, uses C# that is a new object-oriented language and ASP.NET technology, makes use of web controls. The system uses a three-tier structure model and modular design method, uses the process of storing data to achieve the first floor data. By using .NET technology, we can divide the program and code to two different parts, thus, the program and codes is safer, executive efficiency is higher, on the other hand, through setting up security procedures and distributing jurisdiction to increase security. Specific work mainly includes the following aspects:1. The tool that needs to use in system development and the technology that comes down to system are expatiated. Software definition and the requirement analysis of the system are finished. 2. According to the requirement analysisthe, paper has completed the functional design of each module on the inside system. Then according to the detailed design of system, Paper finally has developed completedly "long-distance medical service information system that based on XML and .NET technology".3. Taking the data Stores and transforms as the center, the discussion about the user healthy file is finished. Paper pays attention with emphasis in date transformation strategy between XML documents and relational database, and studies the concrete data storage model and transformation algorithm.
