Data warehouse view definitions are constructed thanks to information sources schemas. When these latter evolve, view definitions may become undefined. In this paper, we propose a system based on mobile agents destined to achieve view definitions repairing or synchronization following schema changes happened at distributed, heterogeneous and autonomous information sources. The proposed solution decreases the synchronization time thanks to parallelism permitted by agents, avoids network saturation by enhancing local processing and increase local intelligence.
