A top-k query retrieves k data tuples with the highest or lowest scores from a databases relation. The importance of the top-k query grows as the size of databases increases and as queries vary for each user. Skyline operations are the representative methods to answer a top-k query. In this paper, we propose a new skyline operation, called Grid Skyline, which uses a grid based partitioning method. Experimental results show that the proposed method improves the existing skyline operations.
