How do I make Workbench display the connecting lines between tables when I define relationships?
How can I display the relationship names in the diagram? It's a 'Show' option. The relationship names are referred to as 'labels' in SQL Developer. So right click in the model, go to 'Show' and toggle on 'Labels.
You read the diagrams first from left to right and then from right to left. In the case of the name-address relationship in following figure, you read the relationships as follows: names can be associated with zero or exactly one address; addresses can be associated with zero, one, or many names.
I had an issue generated a PNG with the relationship lines.
