Data Flow Diagram Level 0

Data Flow Diagram Level 0 can be used in software engineering to represent a system at various levels of abstraction. Higher-level DFDs are subdivided into lower-level DFDs, which contain more information and functional elements. DFD levels are numbered zero, one, two, and higher. The data flow diagram will primarily show three levels: zero-level DFD, one -level DFD, and two-level DFD. It is intended to be an abstraction view, depicting the system as a single process with external entities. This Data Flow Diagram Level 0 diagram represents the entire system as a single bubble with input and output data indicated by incoming/outgoing arrows.
