Data interchange system, data interchange instrument and method thereof

摘要

In a data interchange system that executes a series of process flows among plurality of process executing devices, each process executing device is provided with a unit for interchanging process executing data with other device, and a unit for interchanging with other device interprocess association information that associates a process executed by one device with a process executed by other device, and it performs interchanging of process executing data and of interprocess association information, for example, at a different timing that is not synchronized between both of them. Even a system that has no mechanism for associating processes with one another is thereby enabled to realize associating processes with one another.
