Abstract

The view mechanism can provide the user with an appropriate portion of database through data filtering and integration. In the Web era where information proliferates, the view concept is also useful for XML documents in a Web-based information system. Views are often materialized for query performance, and in that case, their consistency needs to be maintained against the updates of the underlying data. They can be either recomputed or incrementally refreshed by reflecting only the relevant updates. In this paper, we address the issues in deferred incremental refresh of XML materialized views.
