| <p>The Eclipse IDE creates and visualizes the relationship, as |
| well as the relevant relationship attributes of the entities, |
| depending on the type of relation.</p></li> |

| JPA diagram and choose |
| <kbd title="Keyboard button">DELETE</kbd> |
| , or choose <i>Delete</i> in the context menu. |

| <p>Removing a relationship via the JPA diagram also removes |
| it from the application data model and deletes the relationship |
| attributes of the two related entities.</p> |
