Data Flow Diagram Symbols

As previously mentioned, a DFD diagram is one of the most confusing diagrams out there. One reason is the various symbols present within the chart. Needless to say, if you want to fully understand how to read this diagram, then you need to learn the meaning behind each symbol. There are four basic symbols present within every DFD, and they are as follows:

  • Process – This type of symbol is critical since it indicates the exact action that is being performed. Diagrams are not limited to just a single process, since they the entire sequence of actions within the network. In naming a process for a data flow diagram online, it usually starts with a verb, followed by a noun. The Process symbol is represented by a rectangle with rounded corners.
  • Data Flow – Data flow shows the direction the process is headed. It is represented by an arrow that points either left or right. Each direction represents data flow. For example, outgoing arrows show output data flow, while incoming arrows show input data flow from your data flow chart.
  • Data Store – Storage is essential in any data management system. That is why it needs to be included within your data chart.
