Under the environment of data stream

Skyline calculation of the multi-dimensional space will affects the computational efficiency of Skyline point sets of in the sliding windows with the increase of dimension. In order to solve this problem

this paper proposes SQTS algorithm

which tagging tuples by grid index structure to exclude the point sets that not belong to Skyline. Besides

SQTS algorithm introduces SD queues to trigger Skyline maintenance

which avoids checking the overdue data points frequently and improves the calculation efficiency of Skyline of multidimensional space. Finally

this paper gives the results of simulation experiments

which demonstrates that under the environment of multidimensional space

SQTS algorithm improves the calculation efficiency of Skyline point sets; that is to say

SQTS algorithm in this paper is available.
