3DR-tree Model Improvement Based on Enhance of Index Performance

摘要：

　　3DR-tree is an index method using the traditional R-tree to index moving objects.Its defect is that a cube generates when an object remains still for a period of time.For those objects that remain still for a long period of time,many strip cubes will generate.MBR will be overlong or overlarge,thus increasing a great deal of overlap and reducing index performance greatly.This paper is to improve the 3DR-tree model to enhance index performance.On the basis of 3DR-tree,this paper will put forward improving historical data index performance of 3DR-tree through node splitting.3DR-tree is provided with the online data index function by means of tree splitting.
