Incremental Maintenance of Materialized XQuery Views

Materializing the contents of views has important applications including providing fast access to derived database repositories, optimizing query processing based on cached results, and increasing availability. Maintaining the consistency between materialized views and their base data in the presence of source updates is important to ensure that the materialized views are up-to-date. The straightforward solution for this problem is to recompute the view from scratch over the updated sources.
