Finding skyline points over dynamic incomplete database

In database systems with growing data, finding results that best meet the user’s preferences is important. Skyline queries play an essential role, in which only the data items from the database that are not being dominated by the other data items are returned as results. Most of the existing skyline...

Skyline queries play an essential role, in which only the data items from the database that are not being dominated by the other data items are returned as results. Most of the existing skyline approaches assume that the databases are complete which means there are no missing values in the database dimensions.

Missing values change the native of dominance relation and have a negative effect on skyline technique which leads to unsatisfying the transitivity property of skylines and incur cyclic dominance. This problem becomes more complicated when the database is dynamic in which new items are inserted into the database while some items are deleted or updated.
