摘要
数据仓库的刷新过程常被看作在数据源上对物化视图的维护问题 ,但现有的许多物化视图维护算法在不稳定网络中应用会导致数据异常问题 ,本文基于传统的数据仓库模型 ,提出了一种新的物化视图维护算法 ,来完成对数据仓库的有效刷新 ,并通过验证说明该算法的可行性。
The process of refreshing data warehouse is often considered as a problem of the maintenance of materialized views,but in the unstable network traditional algorithms for the maintenance of materialized viesw will lead to anomaly problems.This paper presents a new algorithm for the maintenance of materialized views based on traditional data warehouse model to accomplish the refreshment of data warehouse,and we prove the feasibility of our algorithm by validation.
