A Context Diagram aids in the construction of a Data Flow Diagram
(DFD).
o Phase 2 in the Systems Development Life Cycle (SDLC) is Systems
Analysis.
o Analysts use data and process modeling techniques to show how the
system transforms data into useful information.
o One popular method is to draw a set of data flow diagrams (DFD).
o A DFD shows how data moves through an information system but does
not show program logic or processing steps.
o A context diagram is a top-level view of an information system that shows
the system’s boundaries and scope.
o Review the system requirements to identify all external data sources and
destinations.
o Identify the entities, the name and content of the data flows, and the
direction of the data flows.
