An efficient approach for processing skyline queries in incomplete multidimensional database

In recent years, there has been great attention given to skyline queries that incorporate and provide more flexible query operators that return data items (skylines) which are not being dominated by other data items in all dimensions (attributes) of the database. Many variations of skyline technique...
