摘要
实化视图的维护是数据仓库技术的重要问题,近几年产生了很多的维护算法。已有的维护算法大多是针对单个实化视图的维护。该文提出了一种多实化视图的自维护算法,该算法利用局部约简规则和主外键引用关系生成较小的辅助视图集,使多实化视图和辅助视图集都是自维护的。
The problem of materialized view maintenance has received more attention in the past few years due to its application to data warehousing. A single view self-maintainability has been considered. The paper considers how to make multiple materialized views self-maimainabte to find the minor auxiliary views set and gives an algorithm for the ineremeutal maintenance purpose.
