Which diagram category focuses on horizontal data movement across an enterprise and is suitable for high-level modeling of data flows?

• A. Swim Lane Model
• B. Data Source
• C. Dataflow Diagrams
• D. Data Usage Diagrams

Answer: (C)

Dataflow diagrams are designed to show how data moves between parts of a system, across processes, data stores, and external entities. This makes them ideal for a broad, high-level view of data movement across an enterprise. They let you map the pathways data takes from origin to destination without getting bogged down in implementation details, and you can layer detail by progressing from a context diagram to more detailed levels.

Swim lane models emphasize who performs activities and how processes are cross-functionally coordinated, which centers on responsibilities and process steps rather than pure data movement. Data sources and data usage perspectives focus on where data comes from or how it’s used, not on the enterprise-wide flow of data.
