Materialized views and data warehouses
Nick Roussopoulos · ACM SIGMOD Record · 1998
A data warehouse is a redundant collection of data replicated from several possibly distributed and loosely coupled source databases, organized to answer OLAP queries. Relational views are used both as a specification technique and as an execution plan for the derivation of the warehouse data. In this position paper, we summarize the versatility of relational views and their potential.
