The options under the Relationship Notation menu apply exclusively to an EER diagram. They are grayed out if an EER diagram tab is not selected. The menu options are as follows:
Crow's Foot (IE) – The default modeling style. For an example see Figure 7.42, “Adding Tables to the Canvas”.
Classic – Uses a diamond shape to indicate cardinality.
Connect to Columns
UML – Universal Modeling Language style.
IDEF1X – The ICAM DEFinition language information modeling method
To view the different styles, set up a relationship between two or more tables and choose the different menu options
The relationship notation style that you choose persists for the
duration of your MySQL Workbench session and is saved along with
your model. When MySQL Workbench is restarted, the relationship
notation reverts to the default, the Crow's
Foot
style.
If you plan to export or print an EER diagram be sure to decide on a notation style first. Changing notation styles after objects have been placed on a diagram can significantly change the appearance of the diagram.
