Data Modeling with MySQL Workbench

To create a new data model in the MySQL Workbench, you can:

- Use the File | New Model command, or
- Click the New Model button on the Home page.

Workbench N:M Relationships

- An N:M relationship only exists in a data model (as a non-identifying relationship between two strong entities).

- In a database design, the N:M relationship becomes two 1:N ID-dependent identifying relationships linking the two original tables through a new, third table called an intersection table.

- MySQL Workbench only builds database designs and automatically creates the intersection table with the two 1:N relationships whenever we specify an N:M relationship.
