Abstract

In this paper we propose adaptive data warehouse maintenance, based on the optimistic partial replication of base source data that has already been used in deriving view tuples. Our method reduces local computation at the view as well as communication with the outside sources, and lowers the execution load on the base sources, which leads to a more up-to-date state of the data warehouse view.
