 ===== Data Flow Diagram =====
+{{https://en.wikipedia.org/wiki/Data-flow_diagram}}
+Here are some key characteristics of DFDs:
+* **Standardized symbols:** DFDs use a set of standardized symbols, like rectangles, circles, arrows, and text labels, to represent different elements of the system, such as external entities, processes, data stores, and data flows.
+* **Hierarchical levels:** DFDs can be created at different levels of detail, starting with a high-level overview (context diagram) and then breaking down into more detailed diagrams for each process.
+* **Focus on data flow:** DFDs primarily focus on the flow of data through the system, not the control flow (decision making) or the specific actions performed within each process.
