摘　　要：针对互联网产生的异构数据集成问题,首先提出基于云计算环境下采用中间件方法,利用可扩展标记语言(eXtensibleMarkupLanguage,XML)为交换数据介质,实现异构数据的无障碍获取,特别是对于非结构型数据,采用全文检索方法实现对非结构数据的转换;其次构建异构数据集成的结构模型,并分析模型中各组件的功能;最后研究了实现模型的关键技术,解决了异构数据到XML文档的转换和生成问题,以及对转换后的XML文档的解析问题,采用Java编程语言使用XML文档作为数据交换介质,从而实现异构数据的集成。Aiming at the integration problem of heterogeneous data generated by the internet, firstly, this paper proposes a middleware method based on cloud computing environment, using eXtensible Markup Language(XML) as the exchange data medium,to achieve the barrier free access to heterogeneous data. Especially for unstructured data, this paper uses the omni-directional retrieval method to achieve the conversion of unstructured data. Secondly, the structure model of heterogeneous data integration is constructed, and the functions of each component in the model are analyzed. Finally, the key technologies for implementing the model are studied, and the problems of conversion and generation of heterogeneous data to XML documents, as well as the parsing of converted XML documents, are solved. The integration of heterogeneous data is realized by using XML documents as the data exchange medium in Java programming language.
