Abstract

In this thesis, we are working on the optimized execution of very large number of continuous queries defined on data streams. Our scope includes both classical query optimization issues adapted to the stream data environment as well as analysis and resolution of overload situations by intelligently discarding data based on application-dependent quality of service (QoS) information. This paper serves as a prelude to our view of the problem and a promising approach to solve it.
