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.
