摘要
当前数据库并行处理已经引起了很大的关注,而利用主动触发规则导出数据库数据(如视图)的研究也很多见,但在物化视图增量保持领域这方面的研究还不多见,尤其是利用并行处理能力来解决物化视图增量保持的多触发问题的研究。文章提出了并行环境下物化视图增量保持的主动多触发规则处理机制。
Parallel DB system is widely recognized and production rules in database system can be used to automati-cally maintain derived data such as views ,but writing a set of rules for efficiently parallel maintaining a given view is very difficult.This paper provides a facility from which the system automatically derives set-oriented production rules that maintain the materialized view.
