Abstract: The paper describes realization of distributed approach to continuous queries with kNN join processing in a spatial telemetric data warehouse. Due to dispersion of the developed system, new structural members were distinguished - the mobile object simulator, the kNN join processing service and the query manager. Distributed tasks communicate using JAVA RMI. The kNN queries (k Nearest Neighbour) joins every point from one dataset with its k nearest neighbours in the other dataset. In our approach we use the Gorder method, which is a block nested loop join algorithm that exploits sorting, join scheduling and distance computation filtering to reduce CPU and I/O usage.
