An Annotation Management System for Multidimensional Databases

This paper deals with an annotation-based decisional system. The decisional system we present is based on multidimensional databases, which are composed of facts, dimensions, measures, hierarchies and parameters. The expertise of decision-makers is modelled, shared and stored through annotations. These annotations allow decision-makers to make an active reading and to collaborate with other decision-makers about a common analysis project. Each annotation may be related to multidimensional structures as well as to values available in multidimensional tables.
