  • Choose a template that suits your needs

    Pick a Yourdon and Coad data flow diagram template that fits your system, such as an order processing system, a banking system, or a library system. Click 'Edit This Template' to open it and start mapping how data moves.

  • Sign in or create a free Creately account

    Create a free account or sign in to open the template in the editor. This lets you save your DFD, return to it later, and keep every change synced to your workspace.

  • Open the template and customize it

    Replace the placeholder content with your own system and show how data flows between its parts.

  • Collaborate with your team

    Give others view or edit access, gather inline comments, and resolve them without leaving the canvas. This works well for analysts, developers, and stakeholders reviewing system requirements together.

  • Export, share, or present

    Export your data flow diagram as PDF, PNG, JPEG, or SVG, present it live, or embed or link it in your requirements and design documents.
