An efficient sampling scheme for approximate processing of decision support queries

An efficient sampling scheme for approximate processing of decision support queries

Decision support queries usually involve accessing enormous amount of data requiring significant retrieval time. Faster retrieval of query results can often save precious time for the decision maker. Pre-computation of materialised views and sampling are two ways of achieving significant speed up. H...
