摘要：A new dynamic multi-dimensional index structure called RSR-tree is proposed, in which splitting operations of leaf nodes and non-leaf nodes are performed separatively. RSR-tree retains the sequence ordering of index records in a leaf node of RS-tree and thus reduces the addressing time cost of disk access while reading data files. In addition, it integrates the characteristic of reducing the overlap between brother nodes of R-tree to reduce the query time. The accuracy test and parameter sensitivity test are done on different data sets and the experimental results show that RSR-tree is a dynamic multi-dimensional structure which can efficiently improve query performance and does not bring extra cost of creating index at the same time.
