Using materialized view to accelerate OLAP queries is one of the most common methods used in ROLAP systems. However, high storage and computation cost make this method very diffic...
: In order to acquire a precise and quick response to an analytical query, proper selection of the views to materialize in the data warehouse is crucial. In traditional view select...
We present an optimization method and algorithm designed for three objectives: physical data independence, semantic optimization, and generalized tableau minimization. The method ...
Abstract. The problem of answering queries using views has been studied extensively due to its relevance in a wide variety of data-management applications. In these applications, w...
Many algorithms have been proposed in the area of materialized view maintenance. They provide different capabilities and features, and have different complexity in their implement...
