Passport Status Tracking System - Data Flow Diagram
Data Flow Diagram
- A data flow diagram (DFD) maps out the flow of information for any process or system.
- It uses defined symbols like rectangles, circles and arrows, plus short text labels, to show data inputs, outputs, storage points and the routes between each destination.
- Data flowcharts can range from simple, even hand-drawn process overviews, to in-depth, multi-level DFDs that dig progressively deeper into how the data is handled.
