Abstract

This paper proposes a new symbolic language for the conceptual modelling of computations on data streams. We consider a class of algorithms related to the evaluation of mathematical operators on data streams. A vector model is defined to represent the sliding windows. A graph abstraction is used to model the algorithms. The notation is general enough to be used for visualisation and optimisation of a wide class of data stream processing applications.
