| 中文摘要: |
| HR-树(Historical R-tree)是一种采用重叠技术、将单一版本的结构转换为部分固定结构的高效时空索引结构.介绍了时空索引结构HR-树,为了更直观地说明HR-树的结构及其基本操作算法的执行过程,对基于主存的HR-树可视化演示程序的总体结构设计和主要实现技术作了较详细的描述. |
| 英文摘要: |
| HR-tree is one of the efficient spatio-temporal indexes based on the overlapping technique that transforms a single version data structure into a partially persistent one. In this paper, we introduce the structure of HR-tree, describe the design and method of implementing a visual demo of HR-tree based on main memory. |
