Existing approaches for optimizing queries in information integration use decoupled strategies–attempting to optimize coverage and cost in two separate phases. Since sources tend to have a variety of access limitations, this type of phased optimization of cost and coverage can unfortunately lead to expensive planning as well as highly inefficient plans. In this paper we present techniques for joint optimization of cost and coverage of the query plans. Our algorithms search in the space of… CONTINUE READING
