I did,  but  could not find the related connectors in which tables can I determine the fields of that points on the relation ?

Right-click one of your associations, choose "Attach Note or Constraint", in the dialog set Link Type to "Constraint" and select the two associations that you want the constraint attached to, click OK, double-click the created Constraint element to open its properties, type in "XOR", click OK, resize, move.

Thanks a lot that was helpful, now where can I find the related tables/fields of this relation source and target object

It's in t_diagramobjects.ObjectStyle. The Note has idref=<objectid>; entries for the connected elements.
