Efficient Implementation of Generalized Quantification in Relational Query Languages
The authors' present research aimed at improving their understanding of the use and implementation of quantification in relational query languages in general and SQL in particular. In order to make their results as general as possible, they use the framework of Generalized Quantification. Generalized Quantifiers (GQs) are high-level, declarative logical operators that in the past have been studied from a theoretical perspective. In this paper, they focus on their practical use, showing how to incorporate a dynamic set of GQs in relational query languages, how to implement them efficiently and use them in the context of SQL.
