We have developed a data stream management system that supports declarative stream queries running over high data volumes in a supercomputing environment. To enable specification ...
Execution plans produced by traditional query optimizers for data integration queries may yield poor performance for several reasons. The cost estimates may be inaccurate, the mem...
Peer-to-peer networks are becoming a common form of online data exchange. Querying data, mostly files, using keywords on peer-to-peer networks is well-known. But users cannot perf...
In this paper we describe a prototype implementation of updateable views called “SBQL Views”. The prototype follows a novel approach to view updates based on the Stack-Based Ap...
As video data is penetrating many information systems the need for database support for video data evolves. In this paper we present a generic data model that captures the structu...
