Abstract
In this paper we characterize the efficiency of spatial access structures in
terms of the expected number of data bucket accesses needed to perform a range
query. We derive performance formulas for various kinds of range queries
like intersection, containment, and enclosure queries with different
geometric shapes. The formulas exhibit that range query performance in
general depends on three parameters: the area sum of the data regions,
the perimeter sum, and the number of regions. Only the weights of these
parameters vary from shape to shape and query type to query type. To a wide
extend, our results prove the conjecture that window queries are
representative for range queries in general.
