Warehousing dynamic XML documents

Abstract

Due to the increased popularity of using XML documents in exchanging information between diverse types of applications or in representing semi-structured data, the issue of warehousing large collections of XML documents has become strongly imperative. Furthermore, an efficient XML warehouse needs to be able to answer various user queries about its content or about the history of the warehoused documents. In this paper, we propose a methodology for warehousing dynamic XML documents, which allows a low degree of redundancy of the warehoused data, while preserving critical information. © Springer-Verlag Berlin Heidelberg 2006.
