Processing k-skyband, constrained skyline, and group-by skyline queries on incomplete data

作者：

Highlights：

• We identify and solve the problem of kSB query processing on incomplete data.

• We propose efficient algorithms to address our problem using novel concepts.

• We extend our techniques to tackle CS and GBS queries over incomplete data.

• Extensive experiments verify the effectiveness and efficiency of our algorithms.
