Creating a reflexive association in a CDM

A reflexive association is a relationship between an entity and itself.

Example

The reflexive association Manager expresses that an employee (Manager) can manage other employees.


Steps To create a reflexive association:

  1. Click the Association Link tool in the Palette.
  2. Click inside the entity and while continuing to hold down the mouse button, drag the cursor to a space next to the entity.
  3. Click the entity.

    An association symbol loops back to the same entity.
