In the level–0 diagram, the data store, class roster, does not have the data flow, scheduled classes, flowing into it, rather this data flow connects processes 2 and 3, thus these dfds are not balanced. Data flow diagram (dfd) provides a visual representation of the flow of information (i.e.data) within a system. by creating a data flow. needed in order to complete the processes and the information needed to be stored and accessed. data flow diagrams are widely. used in software engineering. A data flow diagram (dfd) is a graphical representation of a system, which depicts the system's components, data flows and the sources, destinations and storage of data. A.a context diagram is the lowest level dfd; it provides a low level view of a system. b.in order to provide more information, a portion of a level zero diagram ( such as process 2.0) can be dividend into sub processes (for example, 2.1, 2.2, and 2.3, if there are three sub processes).
