提出基于R-tree(空间数据索引)与SB—tree(时间数据索引)相结合的复合索引结构——RSB—tree,以及RSB-tree索引的构建方法和支撑算法。针对小粒度的、近期的时间段数据,实现了结合空间区域和时间数据的时空OLAP分析与查询。
This article proposes a valid index RSB-tree which is the combination structure of R-tree and SB-tree index, the modeling method and sustain algorithm of RSB-tree is researched. RSB-tree is proposed mainly for small granularity and recent time data, through it, spatio-temporal OLAP operations are realized.
