基于XML的分布异构数据集成平台

针对网络环境下异构数据的集成交互问题,提出了基于XML的集成平台解决方案,数据源不需改变存在方式和存储类型,即可实现分布异构数据的无障碍交互.构建了集成平台的结构模型并分析了模型涉及的接口技术、网络传输技术、业务流程引擎、XML相关技术等具体应用.研究了实现模型的关键技术,解决了XML文档生成、转换和映射问题.提出在UML建模的基础上自定义相应XML模式的方法,在XSLT转换中,将样式单与XML设计文档异地存放,减少网络传输流量,便于信息实时交互.将Java,XML和组件技术在本结构模型中进行整合,实现系统.

Intergrated platform of distributed heterogeneous data based on XML

An integrated platform based on XML(extensible markup language) is presented as a solution to resolving the problem concerning the integrating and interacting of heterogeneous data under a network environment.Non-barrier interaction of distributed heterogeneous data can be achieved without changing the existing way or storage type of datum sources.The structure model of the integrated platform was built up.Analysis was made on the concrete application of interface technology,network transmission technology,business process engine and other XML technology that the model concerns.Key technology was studied to materialize the model.Problems concerning the generation,translation and mapping of XML files were solved.The way of defining XML modes on the basis of UML(unified modeling language) modeling was put forward.While translating XSLT(extensible stylesheet language transformations),the stylesheet and XML design files are stored at different sites so as to reduce network transmission volume and help to realize the real-time interaction of data.Java,XML and modular technology are integrated in this model for building the system.
