Context-level Data Flow Diagram (DFD)

"It is common practice to draw the context-level data flow diagram first, which shows the interaction between the system and external agents which act as data sources and data sinks. This helps to create an accurate drawing on the context diagram. The system's interactions with the outside world are modelled purely in terms of data flows across the system boundary. The context diagram shows the entire system as a single process, and gives no clues as to its internal organization." [Data flow diagram. Wikipedia]

"A System Context Diagram (SCD) in software engineering and systems engineering is a diagram that defines the boundary between the system, or part of a system, and its environment, showing the entities that interact with it. This diagram is a high level view of a system. It is similar to a block diagram." [System context diagram. Wikipedia]

Use the Data Flow Diagrams solution from the Software Development area of ConceptDraw Solution Park to draw your own context-level DFDs using the ConceptDraw PRO diagramming and vector drawing software.
