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 ... -
Porting disk-based spatial index structures to flash-based solid state drives
(2022)Indexing data on flash-based Solid State Drives (SSDs) is an important paradigm recently applied in spatial data management. During last years, the design of new spatial access methods for SSDs, named flash-aware spatial ... -
Uncertainty for anonymity and 2-dimensional range query distortion
(2010)In this work, we study the problem of anonymity-preserving data publishing in moving objects databases. In particular, the trajectory of a mobile user on the plane is no longer a polyline in a two-dimensional space, instead ... -
Use-based optimization of Spatial access methods
(2017)Spatial access methods have been extensively studied in the literature, during last decades. Access methods were designed for efficient processing of demanding queries and extensive comparisons between such methods have ...
