We study the problem of continuous relational query processing in Internet-scale overlay networks realized by distributed hash tables. We concentrate on the case of continuous two...
We consider the problem of creating a sample view of a database table. A sample view is an indexed, materialized view that permits efficient sampling from an arbitrary range query...
Modern information systems often store data that has been transformed and integrated from a variety of sources. This integration may obscure the original source semantics of data ...
