| This paper addresses the problem of urgently needed data management techniques for eeciently retrieving requested subsets of large datasets from mass storage devices. This problem is especiallycritical for scientiic investigatorswho need ready access to the large volume of data generated by large-scale supercomputer simulations and physical experiments as(More)
In this paper, we propose a new strategy for optimizing the placement of bin boundaries to minimize the cost of query evaluation using bitmap indices with binning. For attributes with a large number of distinct values, often the most efficient index scheme is a bitmap index with binning. However, this type of index may not be able to fully resolve some user(More)
