Abstract
The development of a BI project goes through several phases. The analysis phase remains an upstream phase, which requires further investigation to overcome the major problems that arise during this phase and to anticipate the resolution of other problems that may arise in the other phases for the development of these BI projects. The complexity of the formalization of the decision-makers' needs (DN) is one of the problems that has been tried to be solved by proposing a new version of the meta-model of the formalization of informational goals, which have been implemented with models. This new version of the meta-model will facilitate to the analyst-designer the identification of decisional data from a set of decision-makers' goals, from which the facts' and dimensions' parameter of the star schemas can be extracted. In the remainder of this paper, the first part provides a state of the art of the DN formalization approaches and their models of representation, then the second part presents our new version of the meta-model of the goals’ formalization, and, finally, this work is completed with the conclusions and a future work part.
