The difference is that a traditional flow chart in the software
world shows the logic or flow of control in a program or system.
A DFD shows the flow of data. They might look similar (boxes and
arrows versus bubbles and arrows) but they're really used for
different things at different times.
It's an important distinction, at least to the Structured Analysis
and Design folks.
