SYSTEM FOR PROCESSING QUERY FOR MOBILE OBJECT DATABASE

摘要

PURPOSE: A system for processing a query for a mobile object database is provided to extract various and precise information, and efficiently search the information on a platform performing an LBS(Location Based Service) and various application fields using the location information of a mobile object. CONSTITUTION: An interface(102) receives the query for the mobile objects from a location information application system(101). A query parsing component(103) parses the inputted query, and separates/parses the query contents into an attribute query and a spatiotemporal query. A mobile object location index(107) is used for efficiently searching the spatiotemporal information for the mobile object stored in the mobile object location database. A query performing component(104) extracts the attribute information of the mobile object from an attribute database through an attribute filter(105) based on a parsing result of the query parsing component, extracts the spatiotemporal information of the mobile object from the mobile object location database through a spatiotemporal filter(106), and merges the extracted attribute and spatiotemporal information.
