Vocabulary for System Interactions

Hi,

Is there a vocabulary for system interactions?

I need to document that, say, System A talks to System B
(bi-directional) using MQ. Or that System C sends a weekly batch file
to System D.

What I would ideally want is 
a) Identify systems (its name, owner etc)
b) Identify system's technology (Mainframe, Java, .Net, etc)
c) Identify inbound, outbound and bidirectional communication from
this system. (the direction of data flow, the frequency, the
technology used, and the kind of data)
d) Identify any sub-systems.

And if there is such a vocabulary, is there any software that help
display it visually?

cheers
Conrad
