Abstract
Many applications were interested in studying objects mobility which allowed the onset of a variety of trajectory data warehouses. As a new paradigm, launched by the evolution of classical ones to take into account mobility data provided by pervasive systems. Mobility data warehouse models was adopted by users in various fields such as those related to marketing, agriculture, health care, etc. However, the proposed conceptual models suffer from dispersed points of view that have to be unified in order to offer generic conceptual support for experts and clerical users. The purpose of this work is to propose a unified conceptual model able to unify different points of view through a generic UML description profile of facts and dimensions well adapted to new concepts imposed by mobility. Thanks to the proposed unified model, users will be able to build themselves their trajectory data warehouses regardless the case of study involving mobile objects.
