Research on query technology in spatial database

Lijing Zhang, Xuanhui He

Abstract

Space operations in spatial database operation is the most complicated and time-consuming operation. Query in the spatial database is a basic feature. I describe several methods about spatial data query and query processing steps. I also gives an algorithm about intersect query in filtering stage in this article to improve the price of database operations, and the efficiency of database queries.
