Abstract
A data warehouse stores materialized views of aggregate data derived from a fact table in order to minimize the query response time.
One of the most important decisions in designing the data warehouse is the selection of materialized views.
This paper presents an algorithm which provides appropriate views to be materialized while the goal is to minimize the query response time and maintenance cost.
We use a data cube lattice, frequency of queries and updates on views, and view size to select views to be materialized using greedy algorithms.
In spite of the simplicity, our algorithm selects views which give us better performance than views that selected by existing algorithms.
