The performance of XML database queries can be greatly enhanced by employing materialized views. We present containment and rewriting algorithms for tree pattern queries that correspond to a large and important subset of XQuery, in the presence of a structural summary of the database (i.e., in the presence of a Dataguide). The tree pattern language captures structural identifiers and optional nodes, which allow us to translate nested XQueries into tree patterns. We characterize the complexity… CONTINUE READING
