【 摘 要 】

One of the fundamental phenomena in life concerns the notion of a preference. Preferencesare a central concept in decision making. Accordingly, the complexity of preferencereasoning has challenged researchers from diverse disciplines ever since. During the pastdecade also in database systems this topic has emerged into a flourishing field. This talkwill address several achievements that have been reached meanwhile. We will cover aspectslike preference modeling and its integration into query languages such as Preference SQL,algebraic preference query optimization and efficient evaluation algorithms for numericaltop-k processing and for skyline computation. Some further challenges towards situatedpreferences, semi-skylines or skyline snippets will addressed as well.Copyright is held by the author/owner(s).
