基于Web Services的实验室异构数据集成的研究

摘要

对传统的异构数据集成方法进行了研究,分析了每种集成方法的优缺点.针对高校实验室各应用系统间数据共享时对数据的实时同步性要求较高的特点,采用模式集成的方法设计了一套基于Web Services的异构数据集成方案,并对服务描述、服务分解和模式映射等关键模块进行了设计.方案采用3层构架,将数据集成的核心功能全部放在了中间层,有效地发挥了Web Services技术在异构数据集成中的优势.%The traditional heterogeneous data integration methods are studied.The advantages and disadvantages of each method are analyzed and summarized.Aiming at the characteristic of requiring temporal synchronization higher of data between different application systems data sharing of university laboratories, a set of heterogeneous data integration scheme based on Web services is designed by using the method of pattern integration, and some key modules such as service description, service decomposition and schema mapping are designed.The scheme adopts 3-tier architecture, and the core functions of data integration are all put in the middle layer, which can effectively give the best advantages with Web Services technology in the heterogeneous data integration.
