heal.abstract |
In this paper, we investigate the problem of view selection for workloads of conjunctive queries under bag semantics. In particular we aim to limit the search space of candidate viewsets. In that respect we start delineating the boundary between query workloads for which cer- tain restricted search spaces suffice. They suffice in the sense that they do not compromise optimality |
