Abstract
Skyline queries ask for a set of interesting points from a potentially
large set of data points. If we are traveling, for instance, a restaurant
might be interesting if there is no other restaurant which is cheaper,
near and has better food. Skyline queries retrieve all such interesting
restaurants so that the user can choose the most promising one.
Essentially, skyline is a set of points that are not dominated by any
other point on all dimensions. In this seminar, I will depict what is
skyline query and its SQL syntax in more detail. All major algorithms for
implementing the skyline operator will also be presented. In addition, I
will also present some variations of skyline queries.
