The purpose of this article is to develop a multidimensional data model that is most appropriate for creating a data warehouse which will be helpful for analysis in taking on medical structure. In today's information systems, the needs of decision-makers require that data be organized around themes or subject of analysis to date and that their formats be standardized despite several sources of data. Hence, the need for multidimensional modeling. The article focuses on the production of the conceptual model, while considering that this is an essential step to the continuity of the other steps of the decision-making process very easily. The choice of the approach used is attached to the users' needs in terms of analysis based on the data saved during a period. The result obtained and presented in this paper is a model of multidimensional data in constellation. Finally, the conceptual model of multidimensional data is behind justified in relation to the expectations of decision makers and other types of existing models in the decision-making systems.
