How It Works
The tool above allows you to create a star schema and to download it as a png or svg image. You can also download the underlying DBML code here, which you can then later import to resume your work.
If you want to customize your star diagram further, click on the "Open in VibeSchema" button. There you can, for example, add notes to tables or columns, declare columns as unique or computed, or link the same dimension to your fact table more than once, such as an order date and a ship date both pointing at a single date table.
VibeSchema also has a separate tool for creating Snowflake schemas.
