Abstract: Traditional database query languages such as Datalog and SQL allow the user to specify only mandatory requirements on the data to be retrieved from a database. In many applications, it may be natural to express not only mandatory requirements but also preferences on the data to be retrieved. Lacroix and Lavency [12] extended SQL with a notion of preference and showed how the resulting query language could still be translated into the domain relational calculus. We explore the use of preference... (Update)

.... satisfaction problems [20] We have also examined the application of the notion of preference in the area of deductive databases [14], but we do not go into these details here for the sake of brevity. Traditional database query languages allow the user to express only the...
.... database field, the problem of expressing and managing user preferences has received growing attention in the last few years [1, 4, 6, 8, 9, 11 15]. In many approaches [1, 7 9, 12] preferences are expressed quantitatively by defining a scoring function that is a weighted...
