MySQL Workbench provides validation modules so that you can test your models before implementing them.

The validation plugins are accessed from the Model menu option. One plugin performs general validation for any Relational Database Management System (RDMS) and the other is MySQL-specific. Beneath these menu items are a number of specific validation tests. Running any one of these tests opens an output window docked at the bottom of the application. Warning messages are displayed on the left side of this window and the tests performed are displayed on the right.

The tasks performed by the validation modules are outlined in what follows.
