The deletion operation in xBR-trees
(2012)In order to design a spatial index, the most important operations are: insertion, deletion and search. We focus on the deletion operation over the xBR-tree, a spatial data secondary memory structure that belongs to the ... -
An efficient flash-aware spatial index for points
(2018)Spatial database systems often employ spatial indices to speed up the processing of spatial queries. In addition, modern spatial database applications are interested in exploiting the positive characteristics of flash-based ... -
Nearest Neighbor Algorithms using xBR-Trees
(2011)One of the common queries in spatial databases is the (K) Nearest Neighbor Query that discovers the (K) closest objects to a query object. Processing of spatial queries, in most cases, is accomplished by indexing spatial ...
