A Personalized Multidimensional Navigation in a Limited Visualization Context

The needs of decision-makers vary greatly depending on their specialties, expertise and knowledge and therefore they do not visualize decision-making data in the same way. Everyone can have their preferences and prerequisites. The multidimensional model, made up of a set of facts analyzed according to different dimensions, is intended for a set of decision-makers and includes all the indicators and axes of analysis of a particular domain. They do not consider the preferences of each decision maker. A personalization phase of this diagram according to the preferences of these decision-makers will improve the decision-making process. In addition, the limited capacity of the devices used (smartphones, tablets, etc.) for consulting the results of OLAP queries presents another challenge for users. In this context, we propose to express the preferences in the form of visualization constraints which will be applied to the schema to represent the result in an incremental way.
