In this paper we present a novel approach for estimating the selectivity of XML twig queries. Such a technique is useful for approximate query answering as well as for determining...
High energy physics scientists analyze large amounts of data looking for interesting events when particles collide. These analyses are easily expressed using complex queries that ...
Adaptive query processing schemes attempt to reoptimize query plans during the course of query execution. A variety of techniques for adaptive query processing have been proposed,...
