Does relationship between two entities are also unique? I mean if a entity e1 has a relationship (r1) with entity j1, and another entity of the first set (e2) has the same relationship with the other entity (j1). The relationship should be (r1) to e2–>j1, or this relationship has its own property. i mean (r2)?

Hi @Sebastian_Ochoa,

If we consider it as the binary relationship then relationship has its own property. but if we consider it as ternary relationship then same r1 is used.
