15 Uml Data Flow. Information flows may be useful to describe. The data flow diagram (dfd) provides a graphical representation of the flow of data through a system.

Coad's object oriented analysis and design (ooa/ood) was a way of visualizing software systems before uml diagrams. Uml 2 has a very good analogue to a data flow diagram: Information flow diagram is uml behavior diagram which shows exchange of information between system entities at some high levels of abstraction.
Data flow diagrams became popular in the 1970s in software development.
15 Uml Data Flow. In software engineering dfd(data flow diagram) can be drawn to represent the system of different levels of abstraction. A data flow diagram (dfd) explains the relationship among different components of a system by showing the flow of data (from which external entities data is coming. Developing a dfd is one of the first steps. In software engineering dfd(data flow diagram) can be drawn to represent the system of different levels of abstraction.
