Abstract

The eXtended Markup Language (XML) has quickly emerged as the universal format for publishing and exchanging data on the Web. As a result, data sources often export XML views over base data. These views may be materialized to achieve faster data access. The main difficulty with this approach is to maintain the consistency of the materialized view with respect to changes of base data. In this paper, we propose an algorithm for the incremental maintenance of XML views. Our algorithm uses the view correspondence assertions for checking the relevance, for the view, of a base update and computes the changes needed for propagating the update to the view.
