How to use this ER diagram template

1. Click Open in the editor. The ER diagram opens on a new page in FlowDiagram — nothing is uploaded and there is no sign-up.
2. Rename, add or delete shapes and drag them where you want; connectors stay attached as things move.
3. Drop in vendor logos from the library — 1,160 of them, including every AWS, Azure and Google Cloud service icon — or restyle it with the colour and theme controls.
4. Prefer text? Edit the DBML below and paste it in through ☰ → Import diagram; the finished model exports to SQL DDL or back to DBML.
5. Export to PNG, SVG or PDF, or press Ctrl+L for a link that carries the whole diagram.
