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.
