Add 'U' in the middle of a line

Question

I am working on some EER diagrams, how can I draw a line with the 'U' inside like the ones in the first picture in this page? http://ulam2.cs.luc.edu/305/spr14/notes/07.html

If it is still not possibile, I hope you will add the support to EER diagrams.

Thank you.

Answer 1

The first picture in the linked article is Figure 7.2 - this figure has no lines with a 'U' inside.

If you are actually referring to Figure 8.1, I am afraid yEd has no edge style/arrow type that resembles e.g. the connection from "employee" to "manager". You may be able to use an edge label to simulate that style though.

Sample GraphML.

Well, the first figure in the linked PDF document is Figure 8.1 I linked to in my answer. Thus, my answer above stands.
