What is the Data flow diagram (DFD): Level 2 template?
Data flow diagrams, or DFDs, map out how information flows through a process or system. These diagrams use symbols like rectangles, circles, and arrows, which are labeled to show data inputs and outputs, storage points, and where the information goes in between each point.
Data flow diagrams vary in how complex they are, and we describe their depth with a label of 0, 1, 2, or 3 and beyond, though most do not go beyond level 3. This diagram template is consequently moderately complicated.
