Topk queries and skyline queries have well explored limitations which recent research have tried to complete through new techniques. In this survey, after resuming such limitations, we consider Restricted Skyline Queries, ORD and ORU approach, Krepresentative minimization queries, Skyline ordering queries, UTK queries approach and Skyrank that aim to overcome them. After introducing and comparing their main concepts, pros and cons, we briefly report the algorithms and confront some of the experimental data collected from the bibliography. To conclude the paper, we summarize the results presented with a short guide on how to select the best approach according to specific needs.
