We propose physical operators for SQLf considering Skyline and Top-k features. Properties of those will be considered during query optimization and evaluation.
Abstract— Top-k pairs queries have many real applications. k closest pairs queries, k furthest pairs queries and their bichromatic variants are some of the ...

Top-k ranks the top k tuples in terms of a user-defined score function while Skyline identifies non-dominated tuples, ie such tuples that does not exists a ...
In this paper, we consider the preference-based query language, "Top-k Skyline", which combines the order-based and score-based paradigms. Thus, "Top-k Skyline" ...
