A main memory database method supporting synchronous cooperative application

There is no good solution of data management for CSCW applications in synchronous work mode. The choice now is no management or duplicate. In the former case, it is common that phone tool discards audio data that is worth to store. In the latter, the performance is still not high, especially when there involves large amount of multimedia data. We take advantages of main memory database technology to support synchronous cooperative work. After analyzes the cooperative design process based an cooperative concept design instance, the paper provides a main memory-based distributed data management model. The model schedules memory according to the features of synchronous cooperative application, greatly improving the performance of data access.
