Disjoint and Overlapping relation in ERD

[Edgars Biezins]

Question: How can I connect multiple entities with Disjoint or Overlaping relation in ERD like Employee, Manager and Programmers in this picture (http://www.sparxsystems.com/enterprise_architect_user_guide/modeling_languages/entity_relationship_diagrams_e.html)? I can connect Employee with Manger entities, but cant connect with same relation Programmer entity.

I have the same problem and I can draw an entity with two or more disjoint/overlapping sub-entities.

Hi,
I see this question posted some time ago. I do not see any resolution posted yet. I am having same issue. Need some help.. Thanks all for looking into this issue... ::)

Finally, I got this work. The example in the EA is actually two connectors which are aligned using a tree style so that they overlap.
 
For example: Using the "Overlapping" connector type from the ERD toolbox, draw a relationship from Programmers -> Employees and another from Managers -> Employees.  Right-click each of these connectors on the diagram and set Line Style | Tree Style - Vertical.  The two connectors should now align and give a similar appearance to the sample diagram shown in the EA help.

Please note, relationship should be drawn from child Entity to Parent Entity so that you can achieve the tree style overlap.

Hope this Helps.

Cheers!!!
