Phase Transitions in Large Networkss of the modeled universe. A formal model of such a database is presented. VQL, which is based on a first order calculus, provides users with the ability of navigating through object versions, and through the states of the universe modeled by the multiversion database.

The Rescue: A Romance of the Shallows,nal aspects of cooperative activities, based on the CoACT cooperative transaction model. The novelty of the language lies in its ability to deal with a broad spectrum of cooperative applications, ranging from cooperative document authoring to workflow applications.

Euclid, Tarski, and Engeler encompassed,r seminal paper of 1990. In this area, databases and query languages are defined using read polynomial constraints. As a consequence of a classical result by Tarski, first-order queries in the constraint database model are effectively computable, and their result is within the constraint model..In p

, a spatial constraint database,ect-oriented framework, with spatial data represented using linear constraints over a dense domain. The query language is the standard OQL, with special functions for constraint solving and geometric operations..A simple geographical application from the French Institute for Geography, IGN, is runni

Degrees of monotonicity of spatial transformations, a hierarchy of monotonicity classes of spatial transformations that is determined by the number of degrees of freedom of the transformations. The result of a monotonic transformation with .degrees of freedom on a spatial database is completely determined by its result on subsets of casdinality at m
