中文摘要: 探讨了oracle 10g spatial空间索引的创建及如何利用空间索引优化空间分析。了解空间查询主要是通过相关的空间算子和空间函数来进行的。利用空间操作符和空间索引的结合, 实现空间查询的优化。

中文关键词: 空间索引空间查询 Oracle Spatial 优化

Abstract:This paper explores the creation of Oracle 10g spatial’s spatial index and how to use spatial index to optimize spatial analysis. The spatial query is mainly carried out by relevant spatial operator and spatial function. Using spatial operator and spatial index can realize spatial query optimization.

keywords: spatial index spatial query oracle spatial optimize
