Add tables from the sidebar to start building the diagram.

Welcome to DER

DER draws a database as a diagram, from the JSON schema that the Framework generates.

  1. Add a schema from a json file, or from the url it is published at.
  2. Pick the tables in the list at the left and they show up on the canvas.
  3. Move them around, and gather the ones that belong together into a group.

Everything stays in this browser, and comes back the way you left it.

Use the button bellow to add a new Schema.
