Construction graphique d'entrepôts et de magasins de données
Nowadays, decisional systems have became a significant research topic in databases. Data warehouses and data marts are the main elements of such systems. This paper presents our decisional support system. We present graphical interfaces which help the administrator to build data warehouses and data marts. We present a data warehouse building interface based on an object-oriented conceptual mode...
متن کاملConstruction, Évaluation et Amélioration Systématiques de Structures de Données
— A very simple formalism, viz. abstract data types, using équations and preconditions, is proposedfor describing the proper tie s oj the object s and the opérations ofa data structure. Two cases studies are detailed: sets, and dictionaries (viz. binary search trees). A small number of rules and heuristics are then developed in order to systematically construct the classical algorithms of searc...
متن کاملConstruction et enrichissement automatique d'ontologie à partir de ressources externes
La construction automatique d’ontologies à partir de textes est généralement basée sur le texte proprement dit, et le domaine décrit est circonscrit au contenu du texte. Afin de concevoir des ontologies sémantiquement plus riches, nous proposons d’étendre les méthodes classiques en matière de construction d’ontologie (1) en prenant en compte le texte du point de vue de sa structure et de son co...
متن کاملConstruction et simulation graphiques de comportements : le modèle des Icobjs
Intuitively, a graphical simulation (virtual world, game,...) can be seen as a finite space inwhich several entities, each having its own behavior, evolve in parallel. So it seems natural touse concurrent languages to program those behaviors. However, it is seldom the case due to thecomplexity of programming and debugging them, because they introduce non-determinismand are ineff...
متن کاملCourbes hyperelliptiques à multiplications réelles et une construction de Shih
Let r and p be distinct prime numbers, let K = Q(cos 2π r ), and let F be the residue field of K at a place above p. When the image of (2 − 2 cos 2π r ) in F is not a square, we describe a geometric construction of a regular extension of K(t) with Galois group PSL2(F). This extension corresponds to a covering of P/K of “signature (r, p, p)” in the sense of [3, sec. 6.3], and its existence is pr...
