Data Flow Diagram How to Draw?

Create a new flowchart, drag a right-angle rectangle from the left graphics area to the canvas, and double-click to insert the input and output data flow names of the system.

Select the input and output graphics of the system, click the "+" outside the border to create a connection line linking these graphics, and draw the top-level data flow diagram of the system from the outside in.

Decompose step by step from the top-level data flow diagram, draw layered data flow diagrams, and stop decomposing when further decomposition involves how to specifically implement a function.

To make the data flow diagram easier to understand, you can add necessary annotations to explain the functions of the elements.

Select the elements within the data flow diagram, set the color, font, and other styles of the graphics/text/lines to optimize the visual effect and make the data flow diagram clearer.

After completion, the data flow diagram can be shared and collaborated with colleagues or clients.

Data Flow Diagram Frequently asked questions

What is the difference between a data flow diagram and a flowchart?

A data flow diagram emphasizes the flow and processing of data, while a flowchart mainly describes the execution flow of a program.



How to set the connection line in a data flow diagram as a curve?

Select the connection line, click 'Line Type' in the top toolbar, change the line to a curve, and click the hollow circle on the curve to adjust the curve's arc.



How to add text content to a connection line?

Double-click the connection line to enter text content. Left-click and drag the text to move its position.



How to change the direction of the arrow on a connection line?

Select the connection line, and the 'Start/End Arrow' in the top toolbar can set the direction of the arrow.



How to modify the color, font, and other styles of shapes in a data flow diagram?

Select the shape in the data flow diagram, and the top toolbar can modify the color, font, and other styles of shapes, lines, and text.



Can control flow appear in a data flow diagram?



What principles should be followed when drawing a data flow diagram?

Follow the top-down, stepwise decomposition principle, ensure consistent data flow direction, have clear input and output in the process, avoid intersecting data flows, and make the diagram clear and understandable.
