Abstract
Methods of optimizing access to a relation queried through a number of predicates. The methods identify one or more candidate predicates of the selection condition that can be used to factorize the selection condition. A gain from using one or more of the candidate predicates to factorize the selection condition is computed. One or more of the candidate predicates that result in a positive gain are factored from the selection condition to produce a rewritten selection condition. The candidate predicates can be predicates that appear exactly in the selection condition more than once and/or merged predicates that may be predicates in the selection condition that overlap.
