在论述R树索引技术的相关概念、数据结构、算法描述及性能分析的基础上,提出了一种改进的R*树空间索引结构-R-tree Index in the paper related to the concept of technology, data structure, algorithm descr iption and performance analysis, based on an improved space for the R* Tree Index Structure

有時候Oracle效能變慢， 做一下分析 讓他認得index.key....，之後查詢、執行操作會提高效率-Oracle performance slow sometimes, so you analyze index.key ...., let him know after the inquiry, the implementation of operations to improve efficiency
