摘要

物化视图的内容具有重要的应用程序，包括提供对派生数据库存储库的快速访问、基于缓存结果优化查询处理以及提高可用性。在存在源更新的情况下，维护物化视图与其基础数据之间的一致性对于确保物化视图是最新的非常重要。此问题的直接解决方案是在更新的源上从头开始重新计算视图。

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.
