Data stream processing addresses a huge variety of application, ranging from processing complex-structured business events to high-volume RFID tag info streams. Some application areas, especially in telecommunication or manufacturing, require guarantees with regard to pre-defined service constraints. In this paper, we outline the cornerstones of a QoS-aware data model comprising functional as well as non-functional properties to describe quality constraints. We will look at the model from a structural point of view as well as from the operational perspective. Since the proposed model is specific with regard to QoS constraint and generic with regard to specific operators, it may serve as a blue-print for a broad spectrum of data stream systems.
