Abstract
Conference Title: 2014 World Congress on Computer Applications and Information Systems (WCCAIS) Conference Start Date: 2014, Jan. 17 Conference End Date: 2014, Jan. 19 Conference Location: Hammamet, Tunisia Trajectory data warehouses were proposed, as an extension of traditional ones to take into account mobility data provided by ubiquitous systems. As a new paradigm, it was adopted by users in various applications such as those related to marketing, agriculture, health care, etc. However the proposed conceptual models suffer from dispersed point of views that have to be unified in order to offer generic conceptual support for experts and clerical users. The goal of this paper is to propose a unified conceptual model able to unify different point of views through a generic description of fact and dimensions well adapted to new concepts imposed by the emergence of pervasive systems. Then, we project the proposed model on different use cases studied in the literature review.
