Can I edit the relationship type or direction?

This is done by double-clicking on the relationship in the graph view to open the Relation view.

Go to the “Linked Entities” tab (Figure 2) to see the details of the relationship type.

Choose the desired relationship by from the drop down list that appears when you select the arrows to the right of the link type (red toggle bars  Figure 2) , and select OK.   A pop-up box appears (Figure 3) indicating the database will be modified accordingly and lets you decide whether or not to proceed with this change. 

Note.  Select NO if you do not wish to change this relationship in the ResNet database.
