Efficient Skyline Querying with Variable User Preferences on Nominal Attributes

Summary: Addresses skyline queries with dynamic nominal preferences (no fixed attribute order). Introduces IPO-tree Search, a semi-materialization storing results to enable evaluation for any preference without full materialization; experiments confirm efficiency.
