Abstract: In a multidatabase transaction model, local agent is the interface between the global transaction manager and the local database systems. It provides transparently accessing local database distributed at different sites for multidatabase systems.Here presented is the local agent model based on two\|phase commit agent（2PCA）. The model integrates database systems that support two\|phase commit protocol or one\|phase commit protocol,and file systems without any transaction processsing protocol. Two methods, using special interface and ODBC, which implement the local agent, are also introduced. The concrete implementation using ODBC is specially addressed. The performance comparison between the two methods is also discussed.
