....the Pareto optimal tuples with respect to criteria. Thus, this is also called the Pareto operator. Skyline has prompted much interest recently, as people see its potential as a basis for or at least a major component of efforts to provide preference queries over relational database systems [1, 3, 6, 7, 8]. Skyline queries can be translated into current SQL, but the resulting queries are inefficient to execute. To handle skyline queries well, the skyline operator would have to be built into the query optimizer, and good algorithms for skyline implemented. We are seeking to devise algorithms for ....

....schemas [13] that would enable reuse of schema parts, assembly of off the shelf schema modules and increase schema quality by encouraging unit tests on interrelated structural (type and table definitions) and behavioral (triggers, user defined routines) elements of a module. Preference queries [12] that have to be answered cooperatively by treating preferences as soft constraints are not supported in SQL:1999. Motivated by the above examples, this paper presents our X Translate system, which allows the users to extend SQL:1999 with general as well as domain specific language constructs. ....

....of these results, the user will have to spend a lot of time and effort, even if he is only interested in small subset of the shown documents or attributes. Therefore, the contribution of our approach is twofold: first, we extend the types of supported conditions in the style of Preference SQL [8], and then, we introduce the concept of generic search patterns [9] 3.2.1. Hard and Soft Conditions. Within SIMPSON, we offer typical hard conditions like title=java or year =2000 , and additionally, we support soft conditions like language = rather German than English , which we also call ....
