| Abstract: | Reverse nearest neighbor spatial database query of spatial query is a research hotspot.Based on the analysis and comparison of the existing reverse nearest neighbor query technology,towards the query efficiency improvement of dynamic data set,a new reverse nearest neighbor query method is proposed based on the R-tree index structure.Comparison and analysis of experiment results show that the program can effectively solve the problem of dynamic data set query. |
