The Outward Transit Pass Questionnsistent probing it is possible to have the power of SQL view queries with multiset semantics, and at the same time have available a spectrum of concurrency from none at all as in previously proposed solutions to the maximum concurrency obtained by issuing all probes in parallel. We then show how op

The Outward Transit Pass Questionized is challenging. Several heuristic algorithms have been proposed in the past to tackle with this problem. In this paper, we propose a completely different approach, Genetic Algorithm, to choose materialized views and demonstrate that it is practical and effective compared with heuristic approach

The Outward Transit Pass Questionhese collections usually define a series of views or temporary tables that constitute . to the question, and finally use an SQL query on those views/tables to get the final answer. We argue that this situation poses problems for traditional approaches to optimization. We show that many of these coll

Nancy E. Bockstael,Kathleen Bellta mining. A similarity measure structures a data set in a general, but weak sense. If the elements are part of a high-dimensional host space (primary space), for instance a data warehouse cube, the resulting structure doesn’t necessarily reflect the real dimension of the embedded (secondary) space.

In this paper, we present a formal framework to describe evolutions of multidimensional schemas and their effects on the schema and on the instances. The fra
