Open publisher page 1 citations

Abstract

Spatial database index is the vital technique for improving the storage efficiency of spatial databases and the spatial retrieval performance.On the basis of the analysis of R tree,this paper puts forward a spatial database index structure CQRtree.This paper also presents the data structure of CQRtree, the insertion, deletion and searching algorithms for its implementation and the comparisons of the CQRtree with R tree. Finally the further research direction is given.
