We provide an evaluation of query execution plans (QEP) in the case of queries with one or two spatial joins. The QEPs assume R -tree indexed relations and use a common set of spat...

Spatial join is an important yet costly operation in spatial databases. In order to speed up the execution of a spatial join, the input tables are often indexed based on their spa...
Abstract. Good estimates of join result sizes are critical for query optimization in relational database management systems. We address the problem of incrementally obtaining accur...
One of the most important operations in spatial access needed systems are spatial joins. Using for processing such operations R-tree like structures is intensively studies now. Th...
The similarity join has become an important database primitive to support similarity search and data mining. A similarity join combines two sets of complex objects such that the r...
