Available online at ScienceDirect Procedia Computer Science 60 (2015) 276 – 283 19th International Conference on Knowledge Based and Intelligent Information and Engineering Systems A mobile agent view synchronization system to uphold a trajectory data warehouse Wided Oueslatia*, Hazar Hamdib, Zeineb Dhouiouic, Jalel Akaichicd ? a Ecole Supérieure de Commerce de Tunis, Université de Manouba, Tunisie b,c,d Institut Supérieur de Gestion de Tunis, Le Bardo, Tunisie Abstract The trajectory data warehouse (TDW) view definitions are constructed from heterogeneous mobile information sources schema that are more and more independent. In fact, they frequently change their content due to perpetual transactions (data changes) and may change their structure due to continual users requirements evolving. Managing appropriately the view definition synchronization is a necessity since, the TDW is considered as the core component of the modern decision support systems. The aim of this paper is to propose a mobile agent view synchronization system to uphold a trajectory data warehouse under schema changes.
