PURPOSE: An apparatus and a method for configuring an index in wireless broadcasting environments, and a system and a method for processing skyline queries using the same are provided to use NDP information of a DSI structure and a data object based on SWEEP order, thereby accurately determining whether a currently read data object is a skyline point. CONSTITUTION: An index table configuring unit(310) configures an index table. The index table includes a DSI structure indexed based on SWEEP order and NDP(Nearest Dominating Point) information of a corresponding data object corresponding to the DSI structure. A broadcasting unit(320) interlinks the index table with the data object. The broadcasting unit broadcasts the index table and the data object. |
