The article discusses how to select the best views in a data warehouse to speed up answering complex queries. By considering both view size and how often a query is asked, the new algorithm can choose views that are more likely to be useful in the future. This approach helps reduce the time it takes to get answers to queries, even though it may cost a bit more to evaluate all the views. The new algorithm is better at selecting views that can handle a larger number of queries compared to the traditional method.
