Data synchronization provides a feasible solution for improving data accessibility and consistency in mobile database systems. Flexible and efficient data synchronization, however, remains a challenging problem in mobile database applications over mobile ad-hoc networks (MANET). This paper proposes a novel object-oriented data synchronization (OODS) schema in mobile database systems, for providing a flexible and efficient data synchronization service to applications running over MANET. OODS employs publication/subscription mode and DB4O as the database engine. Subscribers can recognize update of publishing schema automatically. On publishers, publishing schema and conflict solutions can be user-defined or inherited from the schema inheritance tree. Sample data were configured to conduct performance evaluation over Bluetooth Piconet. The obtained results indicated the efficiency and feasibility of the schema and its potential for synchronizing data in mobile database over MANET.
