spatial relationship determines how two or more spatial objects are related or connected in …

Indexes are special purpose data structures, designed to facilitate and speed up the access
to the contents of a file. Indexing has been actively and extensively investigated in DBMSes …

Index structures are powerful tools for improving query performance and reducing disk
access in database systems. Multi-dimensional indexes, in particular, are used to filter …

Processing of spatial queries has been studied extensively in the literature. In most cases, it
is accomplished by indexing spatial data using spatial access methods. Spatial indexes …

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 …

Efficient query processing in spatial databases is of vital importance for numerous modern
applications. In most cases, such processing is accomplished by taking advantage of spatial …

To optimize the processing of spatial queries, there is an increasing interest in combining
spatial index structures with modern storage devices like flash-based Solid State Drives …

Efficient spatial query processing in Graph Database Management Systems (GDBMSs) has
become increasingly important owing to the prevalence of spatial graph data. However …

Spatial indexes are important in spatial databases for efficient execution of queries involving
spatial constraints. The xBR^+-tree xBR+-tree is a balanced, disk-resident, Quadtree-based …

A major part of the interface to a database is made up of the queries that can be addressed
to this database and answered (processed) in an efficient way, contributing to the quality of …
