MySQL Workbench Tutorials
MySQL Workbench automatically discovers that address.city_id has been defined as a foreign key referencing the
city.city_id field. Drop the country table onto the canvas and immediately you should see the relationship between the
country table and the city table. ( See Figure 5.1, “The sakila EER diagram” to view a PNG file of all the relationships in
the sakila database.)
Choose the Properties tab of the panel on the lower right and then click one of the tables on the canvas. This displays the properties
of the table in the Properties window. While a table is selected you can use the Properties window to change a table's
properties. For example, entering #FF0000 for the color value will change the color accent to red.
Changing the color of a table is a good way to identify a table quickly — something that becomes more important as the number of
tables increases. Changing the color of a table is also an easy way to identify a table in the Model Navigator panel. This panel,
the uppermost panel on the left side of the screen, gives a bird's eye view of the entire EER canvas.
Save your changes to a MySQL Workbench Models file (mwb) by choosing SAVE from the FILE menu or by using the keyboard
command Ctrl S.
4.2. Using the Default Schema
When you first open MySQL Workbench a default schema, mydb appears as the left-most tab of the PHYSICAL SCHEMATA section
of MySQL Workbench. You can begin designing a database by using this default schema.
Figure 4.2. The default schema
To change the name of the default schema, double click the schema tab. This opens a schema editor window docked at the bottom
of the application. To undock or redock this window, simply double click anywhere in the editor title bar.
