Evaluating skyline queries over vertically partitioned tables
José Subero, Marlene Goncalves · 2013
In recent years, many researchers have been interested in the problem of Skyline query evaluation because this kind of queries allows to filter high volumes of data. Skyline queries return those objects that are the best ones according to multiple user's criteria. In this work, we propose two algorithms to evaluate Skyline queries over Vertically Partitioned Tables (VPTs). Additionally, we have performed an experimental study that shows our proposed algorithms outperform the existing state-of-art algorithms.
