Abstract

The ability to store information contained in XML documents for future references becomes a very important issue as the number of applications which use and exchange data in XML format is growing continuously. Moreover, the contents of XML documents are dynamic and they change across time. However, storing all document versions in an XML data warehouse would introduce a high level of redundancy. Nevertheless the ability to store XML documents together with their different versions across time is often required. Our paper proposes a novel approach for storing changes of dynamic XML documents in time with less overhead so earlier versions can be easily queried. We show how our proposed consolidated delta is built, with steps and rules of the algorithm involved and we demonstrate the efficiency of the versioning approach in terms of storage and retrieval using some test data.
