An Efficient Refreshment Algorithm for Materialized View Considering the Update Frequencies
|
Abstract:
For the materialized views in the fast LAN or computing grid environment, it is a very important problem that how to refresh them efficiently when data sources have changed. In this paper, we take the update frequencies and the size of source relations into account and present a partition strategy and an efficient algorithm by creating auxiliary views. Our algorithm may decrease the cost of join operation and communication on network as low as possible.
