An Optimisation Scheme for Coalesce/Valid Time Selection Operator Sequences

Abstract

Queries in temporal databases often employ the <italic>coalesce</italic> operator, either to coalesce results of projections, or data which are not coalesced upon storage. Therefore, the performance and the optimisation schemes utilised for this operator is of major importance for the performance of temporal DBMSs. Insofar, performance studies for various… (More)
