What is the data flow diagram: level 1 template?
A data flow diagram (DFD) maps out the flow of information for a process or system using defined symbols such as rectangles, circles, arrows, and text. DFD levels are numbered based on how many details are needed. For example, a data flow diagram: level 1 provides more detailed breakout pieces than a level 0 DFD, but less than a level 2 DFD.
