Data Flow Diagram should be the model you think of. How does the data flow? Split apart and recombine?
It might be easier to understand as a flow diagram for a major industrial plant, functions and programs like robots and major machines.
- tuatoru 4y agoThe key part of the Data Flow Diagramming method (as I was taught it, anyway) was not graphical: the Data Dictionary. This was, as the name implies, a dictionary that was the single source of truth for definitions of data items: meaning, representation, meaning of enumerated values, synonym and their business contexts, examples, caveats, etc. Easily implemented as a single table in your database. Never done these days, although it would probably simplify learning a system quite a lot.
