Pher Pher A data flow diagram (DFD) is a graphical representation of the "flow" of data through an information system‚ modeling its process aspects. Often they are a preliminary step used to create an overview of the system which can later be elaborated.[2] DFDs can also be used for the visualization of data processing (structured design). A DFD shows what kinds of data 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
