One of the distinguishing characteristics of a data stream system is 'a continuous query operating on dynamic data' as opposed to 'static data processed by instantaneous query' in DBMS. In this paper, we propose a system of operators to process a continuous query on sliding windows over streaming data. We use the pre-defined notion of sliding windows over a data stream and provide an abstraction for a system of operations that supports evaluation of a continuous query on sliding windows. The model consists of a basic data window, a set of transition operations, a set of processing operations and the operation of binding number of streams together before processing.
