This student assignment system data flow diagram depicts the graphical processing of data in a system in terms of input and output. The student assignment system data flow diagram contains some symbols for drawing the data flow diagram. The context level data flow diagram is known as the 0 level dfd. The context-level data flow diagram (DFD) is a diagram that describes the entire system. The (o) level DFD defines all user modules that run the system. The context-level data flow diagram of the Student management system project shown below shows that a single Admin user can operate the system. After logging into the system, the administrator performs all activities. Start making data flow diagrams using in-built templates and symbols provided by EdrawMax.
