4.1 | 3 | If you select two entities in the entity tree (outline view), you can then click the "New Relationship" action and it will bring up the New Relationship Dialog. I love the new versions of this because it even has an option to add the foreign key attribute for you, too, for non-many-to-many's (though I don't recall what it does if you don't use Project Wonder – it uses prototype 'id' when you have Project Wonder). |

| 5 | In the dialog, you can select which sides (or both) of the relationship are to-many, you can name the relationships, you can optionally have it create a foreign key attribute for one-to-many (single foreign key), or you can select the join attributes. |
