Study of Hybrid Tree Index and Database Engineer on Spatial Data
This paper discusses some key technologies about Spatial Database System,optimizes the spatial index,designs a hybrid tree based on R-tree and 2K tree and the efficiency of spatial data access is improved.Simultaneity,a spatial database engineer based on OpenGIS criterion and this hybrid tree has been implemented,it can manage the spatial data availability and guarantee the share of data and connective of operator,and this SDE has a good performance in our experiment.
