Book 2000posed to a collection of individual surveys. In par ticular, the terminology and the style of presentation have been standardized, and there are multiple cross-references between the chapters. The idea of constraint databases goes back to the late Paris Kanellakis.

Radiographic Analysis of the Femur on . and Constraint Logic Programming (CLP). The original motivation was to combine work in these two areas, with the goal of obtaining a database-style, optimizable version of constraint logic programming. The key idea was that the notion of a tuple in a relational database could be replaced by a

Selection of a Surgical Strategyry languages give a natural analog of relational calculus in the geometric context, a crucial question concerns how to extend standard aggregation constructs from the relational model to the geometric setting. This question has two components.

We have also seen some results on restricting the language, and the resulting expressive power, in Section 4.4.1.
