Back in the Dark Ages (mid-1980s), I used Data Flow Diagrams from Structured Analysis a fair amount, and found them very useful.
My current employer loves UML. I normally use BOUML, which doesn’t do non-UML drawings.
What is the UML drawing that corresponds to the Data Flow Diagram?
If there isn’t one, what is the recommended UML diagram to present the corresponding data?
Probably the closest thing is the activity diagram. It’s not quite the same; more influenced by flow chart than dfd. However: you can do some of the useful things in DFDs, e.g. ADs do support concurrency and differentiate control flow from dataflow.
More details on comparisons & differences in this question.
[fwiw, I still use DFDs: they’re simpler and more elegant in many circumstances]
