Abstract
A method for processing data performed in a data processing system having a storage unit is provided which includes: creating a spatial index comprising a leaf containing location information and attribute information with respect to a plurality of objects to be searched, and storing the spatial index in the storage unit; and referring to the spatial index stored in the storage unit in response to an input of a search request including location information and attribute information for searching the object to be searched, and extracting the object to be searched that agrees with the search request. With this configuration, a spatial search with subsidiary condition search can be processed at high speed, without merging results of both searches.
