This work led us therefore to propose a new taxonomy of patterns and consequently to identify a new set of aspect-oriented design patterns. We propose...

Conception et manipulation de Bases de donnees Dimensionnelles à contraintes

In decisional systems framework, my thesis focuses on the conception and the querying of multidimensional data.We provide a dimensional model organising data in a constellation of facts (subject of analysis) associated withdimensions (axes of analysis). These dimensions are flexible because each dimension instance can belong to oneor several hierarchies (perspectives of analysis...
