Which component is described by a Data Flow Diagram?

• A. A graphical description of the flow of data within an organization, including data sources/destinations, data flows, transformation processes, and data storage
• B. A list of clinical practice guidelines
• C. A chart of equipment maintenance
• D. A schedule of staff shifts

Answer: (A)

A Data Flow Diagram maps how information moves through a system and where it is stored. It uses external entities to show data sources and destinations, data flows to show the paths data takes, processing steps to represent transformations or activities that process the data, and data stores to indicate where data is kept. This combination gives a graphical description of the flow of data within an organization, covering who or what produces data, how that data moves, how it’s transformed, and where it’s stored. It isn’t about clinical guidelines, equipment maintenance, or staff schedules, which are separate kinds of documentation.
