摘要: The skyline clause—also called the Pareto clause—recently has been proposed as an extension to SQL. It selects tuples that are optimal with respect a set of designated attributes. This is maximal vector problem in relational context, but it represents powerful SQL which allows for natural expression on-line analytic processing (OLAP) queries and preferences queries.
