Résumé:
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 spatial joins algorithms, among which one is a novel extension of a
strategy based on an on-the-fly index creation prior to the join with
another indexed relation. A common platform is used on
which a set of spatial access methods and join algorithms are
available. The QEPs are implemented with a general
iterator-based spatial query processor, allowing for pipelined QEP
execution, thus minimizing memory space required for intermediate
results.
