Level 0 process flow diagram
A process flow diagram (PFD) is a diagram commonly used in chemical and process engineering to indicate the general flow of plant processes and equipment. The PFD displays the relationship between
major equipment of a plant facility and does not show minor details such as piping details and designations. Another commonly used term for a PFD is a flowsheet Note that: External entities also are called terminators because they are data origins or final destinations. An external entity must be connected to a process through a data-flow. A hierarch of diagrams is typically created that start from the Context diagram, which is said to be at 'level 0' in the hierarchy.

DFDs show the flow of data from external entities into the system, showed how the data moved from one process to another, as well as its logical storage. Data Flow Diagram.
A data flow diagram (DFD) illustrates how data is processed by a system in terms of inputs and outputs. As its name indicates its focus is on the flow of information, where data comes from, where it goes and how it gets stored.
