为XML文档开发数据仓库涉及两个主要过程：一个是通过将XML原始文档处理到指定的数据仓库存储库来创建数据仓库；另一个是查询，通过应用技术来更好地回答用户的查询。本文主要研究第一部分；即确定构建XML文档数据仓库的系统方法，特别是将数据从底层XML数据库传输到已定义的XML数据仓库。所建议的构建XML数据仓库的方法涵盖的过程包括数据清理和集成、摘要、中间XML文档、更新/链接现有文档和创建事实表。在本文中，我们还提出了一个案例研究如何将这种方法付诸实践。我们在上述所有流程中都使用了XQuery技术。
Developing a data warehouse for XML documents involves two major processes: one of creating it, by processing XML raw documents into a specified data warehouse repository; and the other of querying it, by applying techniques to better answer users’ queries. This paper focuses on the first part; that is identifying a systematic approach for building a data warehouse of XML documents, specifically for transferring data from an underlying XML database into a defined XML data warehouse. The proposed methodology on building XML data warehouses covers processes including data cleaning and integration, summarization, intermediate XML documents, and updating/linking existing documents and creating fact tables. In this paper, we also present a case study on how to put this methodology into practice. We utilise the XQuery technology in all of the above processes.
