Given a multidimensional data set, a skyline query returns the interesting points that are not dominated by other points. The actual cardinality (s) of a skyline query result may vary substantially from the desired result cardinality (k). An approach called skyline ordering is used that forms a skyline based partitioning of a given data set, it provides an ordering among the partitions. The constrained skyline query results the skyline points that may be too small in some cases. The paper proposes a new method for finding the arbitrary number of points for the constrained skyline query.
