Abstract

Materialized views and their potential have been recently rediscovered for the content of OLAP and data warehousing. A flurry of papers has been generated on how views can be used to accelerate ad-hoc computations over massive datasets. In this chapter we introduce and comment on some main-stream approaches for defining, computing, using and maintaining materialized views with aggregations in a large data warehouse.
