Data streams are data in infinite, continuous, arriving at fast rate and in large amount. Histograms have been widely used to capture attribute value distribution statistics for query optimizers. Recently, histograms have also been considered as a way to produce quick approximate answers to decision support queries. We are interested in an efficient algorithm for choosing the bucket boundaries in...
The fact of the increasingly globalized economy has driven many corporations to expand their business beyond their traditional database access. They want to access heterogeneous data source by a uniform query interface. One of the ways to view these systems is to postulate a global schema that provides a unifying data model for all the data sources. A query processor is in charge of reformulating...
As distributed heterogeneous database multiple different physical locations, so will inevitably lead to a heterogeneous web server access to the database server response time difference, so in a distributed heterogeneous database access must be considered the database response time. This design technique based on hibernate database middleware, the middleware on the basis of the shortest waiting time...
