Which diagram emphasizes a vertical view of data movement through procedures and is best for illustrating detailed workflow to implement, monitor, and control data according to policies?

Which diagram emphasizes a vertical view of data movement through procedures and is best for illustrating detailed workflow to implement, monitor, and control data according to policies?

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

Answer: (A)

Data usage diagrams center on how data is used and governed as it moves through procedures. They lay out a vertical sequence of steps where data is collected, processed, stored, and accessed, with explicit policy-based controls at each point. This alignment makes them ideal for showing the workflow needed to implement, monitor, and enforce data policies, including who uses data, for what purpose, what checks apply, and how compliance is tracked along the entire path. In contrast, data flow diagrams focus more on the movement between processes and data stores, swim lane models emphasize who does what across steps but not the governance controls themselves, and data sources just identify where data comes from. So for illustrating a detailed, policy-driven workflow to implement, monitor, and control data, a data usage diagram fits best.
