This DFD level 0 example shows how such a system might function within a typical retail business. It shows the system in its, entirety as a single process. A level 0 data flow diagram (DFD), also known as a context diagram, shows a data system as a whole and emphasizes the way it interacts with external entities. Each time a process is expanded to a lower level, the lower level diagram must show all the same data-flows into, and out of the higher level process it expands. Data flow diagrams can be used to provide the end user with a physical idea of where the data they input ultimately has an effect upon the structure of the whole system from order to dispatch to report. they are not different they are similar as level 0 DFD A context diagram is a top level (also known as "Level 0") data flow diagram. It displays how the entire system interacts with external data sources and data sinks. The so-called zero level is followed by DFD 0, starting with process numbering (e.g., process 1, process 2). Diagram Zero 2. In this level, we highlight the main functions of the system and breakdown the high-level process of 0-level DFD into subprocesses. Processes are labeled 1.0, 2.0, etc. It’s a basic overview of the whole system or process being analyzed or modeled.

This is the most basic type of DFD where all the processes and storage is represented by a single process. DFD Level 0 is also called a Context Diagram.

This will be utilized in checking the details of the user. In the next, the so-called first level – DFD A single process node on a high level diagram can be expanded to show a more detailed data flow diagram.
