Data synchronization model for collaborative system integration
.面向协同系统集成的数据同步模型*

In order to carry out data synchronization of heterogeneous database in collaboration process,the paper presented a new data synchronization model based on agent technology.In the model,the local agent monitored the changes of the data using data synchronization listener in real time.And the global agent tested system using data synchronization detector periodically and generated corresponding synchronization commands that were distributed execution by the global agent,and solved the data synchronization problems of heterogeneous database in collaborative system.Finally,the data synchronization model was applied to a "project control and management system".The result shows the availability and effectiveness of the model and the accuracy and real-time of the data synchronization mechanism.
