So for example, it could be that the MDM system is the master and the transactional systems are the slave systems.
例如，MDM系统是主系统，而事务性系统是从系统。

For availability, this computing system was a redundant design, with two sets of processors and buses and the ability to switch between a master and a slave if the master was found to be unresponsive.
The mathematical model of master-slave synchronous winding control system is established here, and the design methods of the system hardware and control method are introduced in detail.
