The content level data flow diagram depicts the system under consideration as a single high-level process, followed by the system's relationship with other external entities. Because a Context Level Data Flow Diagram is a subset of a Data-Flow Diagram, knowing a little bit about Dataflow Diagrams can benefit. A Data-Flow Diagram (DFD) is a graphical representation of data flow through an information system. DFDs are three key components of the structured-systems analysis and design method. Each DFD may depict several processes, each with data flowing into and out of it. If more detail is required within a specific process, the process is decomposed into several smaller functions in a lower level DFD.
