MAX and MIN are two important aggregates offered by the original SQL specification. In the paper, we propose a novel mechanism, i.e. the exemplary sketch, to evaluate MAX and MIN over sliding windows with various size in the data stream environment. Performance analysis shows that evaluating MAX or MIN over w sliding windows with various size using the exemplary sketch takes O(ln n) expected am...
