EFFICIENT QUERY PROCESSING BASED ON QUALITY PREFERENCES IN CLOUD DATA STORAGE

A Spatial positioning inquiry, positions items basing on the characteristics of elements in their spatial neighborhood. For instance, utilizing a land office database of flats and lands for sale, a client may need to retrieve the items basing on their spatial ranks, characterized by gathering the characteristics of different elements (e.g., shopping malls, sch ools, hospitals, theaters, super market, and so forth.) inside of their spatial neighborhood. For searching the spatial data i.e., some m multidimensional spaces the regular indexing systems are not suitable. To address this issue, here a novel tree struct ure introduced. And performs some tests on the spatial data collected from different sources and prove that this structure performs well for the multidimensional data
