MOVING OBJECT DATABASE SYTEM HAVING FUNCTION OF INDEX MANAGEMENT AND INDEX MANAGEMENT METHOD THEREOF

摘要

A moving object data system having an index managing function for improving access speed to moving object data and a method for managing the index are provided to dynamically support insertion/search/deletion of a moving object by using the present index. A query processing component(200) inserts location information of the moving object by a location report of the moving object or processes a search/deletion request for the stored location information of the moving object. A data managing component(300) stores/manages the location information of the inserted moving object. An index managing component(400) includes more than one index component(500) differently applied to each moving object, and manages each index component according to the insertion/search/deletion request for the location information of the moving object. A disk managing component(600) stores the location information and the index information of the moving object. A screen outputting component(100) outputs location of the moving object or the information included by the searched object to a screen.
