The ability to store and query uncertain information is of great benefit to databases that infer values from a set of observations, including databases of moving objects, sensor r...
Decision support applications involve complex queries on very large databases. Since response times should be small, query optimization is critical. Users typically view the data ...

Moving objects (e.g., vehicles in road networks) continuously generate large amounts of spatio-temporal information in the form of data streams. Efficient management of such strea...
Research on query optimization has focused almost exclusively on reducing query execution time, while important qualities such as consistency and predictability have largely been ...
Wireless sensor networks with multiple users collecting data directly from the sensors have many potential applications. An important problem is to allocate for each user a query r...
