Skyline queries which received an interesting attention to the database and data mining field and its main advantage is it is used for multi-criteria decision making. Advanced query operators, such as skyline queries are necessary in order to help users to handle huge amount of data from a large database by identifying set of non-dominated points. Skyline queries means it retrieve set of non-dominated points or better points from the given data points. It provides an interactive environment for information retrieval that help user to get answer for the given preference based query. This survey paper discusses about various skyline query processing algorithms and its different application in various fields includes spatial database, subspace, network, distributed environment etc. This study gives an overview about the existing algorithms for skyline query processing technique and different applications.
