Abstract

Due to the increasing size of data warehouses it is often infeasible to materialize all possible aggregate views for Online Analytical Processing. View selection, the task of selecting a subset of views to materialize based on knowledge of the incoming queries and updates, is an important and challenging problem. In this paper we explore Dynamic View Selection in which the distribution of queries changes over time, and a subset of a materialized view set is updated to better serve the incoming queries.
