| 英文摘要 | R-tree is incapable of managing spatial objects in concurrent environment. We proposes the CQR-tree (concurrent quad-tree & R-tree) to satisfy this situation, which is easy to integrate with existing R-tree systems. Firstly, we point out the limitation of R-tree in concurrent environment and the limitation of the R-link tree in the special system. Secondly, we introduce the CQR-tree to solve the problem. Thirdly, we list the algorithms of the CQR-tree, including insert, add, and delete operators, and the query strategy. Then, some experimental results confirm that the proposed CQR-tree performs well in concurrent environment. |
