Abstract

In this paper author presents an experiment, which shows that it is possible to form a federation of data warehouses that may simulate effectively one, “super” data warehouse. There is no need to create complete ETL tool to load data from source data warehouses into one, dedicated data warehouse. Good relations between global schema and local schemas extracted during schema integration are indispensable to create an effective federation.
