We call layout a diagram plus the editors which can be open in the same tab.
Tables, columns and foreign keys can be edited directly in the layout, by double-clicking them.
For a better understanding of the schema you can create multiple layouts.
One table may show in any layout. Add table to layout by drag and drop from the tree pane.
The layouts are saved together with the schema to the project file. You may close a layout, it still will be saved, and later reopen it.
Select multiple tables with the mouse and Control down. Right-click to get options, like create table groups.
Drag the layout with the right-mouse button. Zoom with the ALT key and the mouse.
Columns can hide in the diagram. Double-click the table header to get to the table dialog.
Besides Relational Data Browse, can fast view table data from database by clicking the table header with
CTRL + SHIFT down.
Foreign keys are drawn in the layout automatically. You cannot influence the drawing of foreign keys.
They require a minimum space between tables to be drawn. If this fails a marker is painted on the foreign key icon.
Foreign keys can be drawn in layout in two modes : pointing to table ( default ) and pointing to column.
Pointing to column may merge two lines in a single line.
Foreign keys can be drawn using different notations. Change this from the menu:
