A data flow diagram (DFD) is a visual map that shows how data moves through a system or a process. It uses symbols like arrows, rectangles, circles, and text labels to represent data flow or transmission.

Data flow diagrams visually represent systems and processes that would be hard to describe in just words. You can use these diagrams to map out an existing system and make it better or to plan out a new system for implementation. Visualizing each element makes it easy to identify inefficiencies and produce the best possible system.
