Tables
Tables are the building blocks of your schema. Each table on the canvas represents a database table—complete with columns, data types, indexes, and relationships you can define visually.
Adding a table
Click Add Table in the toolbar (or press T).
Click on the canvas to place it.
Type a name—the table starts with a default id column.
If you place a table over an existing group, it'll automatically become a child of that group.
Editing
Click a table to select it. The left panel lets you edit the table and its contents:
Name — click the pencil icon or double-click the table header.
Columns — use Add Column to add columns. Each column has a name, data type, nullable flag, and optional attributes like default values and comments.
Indexes — use Add Index to define indexes on one or more columns.
Color — pick from 12 colors via the color swatch in the footer.
Comment — add a table-level comment from the options menu.
Notes
Deleting a table also removes its columns, indexes, and connected relationships.
Drag a table into a group region to add it to that group.
