I have to develop an integration concept to integrate my software as a subsystem into an enterprise information system which communicates with other information systems in other institutions.
I want to show a diagram which explains how the several subsystems are connected and which data is communicated between the subsystems. My problem is that I’m not sure if there is in the UML language a diagram-type that supports modeling of complete information systems.
I thought about the deployment diagram, but I am not sure if it is the right. I don’t want to start an then recognize that it is the wrong way.
Is there any advice which diagram should be used, or if there is an alternative modeling language for complex information systems?
A component diagram is what you want – see chapter 25 of “The Unified Modeling Language User Guide”.
