Description:
In ERwin 7.x we create one-to-one relationships by going to the Relationship Editor, checking the "Exactly" radio button, and enter the number "1". In ERwin r8 the design has changed, how do we create a one-to-one relationship in ERwin r8?
Solution:
In ERwin r8, go to the Relationship Editor, under "Cardinality Properties" there is a field labled "Cardinality Value". Entering a value of "1" in that field will create a one-to-one relationship.
