A data-flow diagram template example is a way of representing a flow of data through a process or a system. As per the DFD template, it can be divided into logical data flow diagrams describing the flow of data through a system to perform certain functions of a business. A data flow diagram template can be used for the visualization of data processing and show what kind of information will be input to and output from the system, where the data will come from and go to, and where the data will be stored. It should be noted here that the data flow diagram template does not show information about the timing of processes or information about whether processes will operate in sequence or in parallel.
