After a quick survey of the social and economic conditions of research, the paper addresses itself to : i) the influence of language theories on AI research : neuropsychology, psychocognitive sciences, transformational gramm...

Algèbre OLAP et langage graphique

This article deals with OLAP systems based on multidimensional model. The conceptual model we provide, represents data through a constellation (multi-facts) composed of several multi-hierarchy dimensions. In this model, data are displayed through multidimensional tables. We define a query algebra handling these tables. This user oriented algebra is composed of a closure core of OLAP operators a...

Contraintes pour modèle et langage multidimensionnels

This paper defines a constraint-based model dedicated to multidimensional databases. The model we define represents data through a constellation of facts (subjects of analyse) associated to dimensions (axis of analyse), which are possibly shared. Each dimension is organised according to several hierarchies (views of analyse) integrating several levels of data granularity. In order to insure dat...
