Trajectory data warehouse modeling based on a Trajectory UML profile: Medical example

Trajectory data is a new concept appeared with the continuous mobility imposed by social and professional daily life activities and the advance of mobile devices used to accomplish missions while moving. Trajectories data can be used either for transactional and analysis purposes in various domains (heath care, commerce, environment, etc.). For this reason, modeling trajectory data at the conceptual level is an important rung leading to flourishing implementations. However, there is not till now a recognized model answering all the requirements for modeling trajectory data, and the trajectory data conceptual modeling remains an open line of research. Hence, we propose in this paper a rich conceptual schema modeling for trajectory data and trajectory data warehouse which is the basis of future efficient storage system and consequently meaningful interpretations and efficient analysis in ubiquitous applications.
