Speeding up Warehouse Physical Design Using a Randomized Algorithm

  title={Speeding up Warehouse Physical Design Using a Randomized Algorithm},
  author={Minsoo Lee and Joachim Hammer},
A data warehouse stores information that is collected from multiple, heterogeneous information sources for the purpose of complex querying and analysis. Information in the warehouse is typically stored in the form of materialized views. One of the most important tasks when designing a warehouse is the selection of materialized views to be maintained in the warehouse. The goal is to select a set of views in such a way as to minimize the total query response time over all queries, given a limited… CONTINUE READING
