   The Relationships editor opens.

2. Click the General tab.

   The General tab opens.

3. Change the relationship type using one of the following relationship types and then click OK.

   Identifying

   Specifies an Identifying relationship, which is a relationship between two entities in which an instance of a child entity is identified through its association with a parent entity. No nulls are allowed in identifying relationships.

   Non-Identifying

   Specifies a Non-Identifying relationship, which is a relationship between two entities in which an instance of the child entity is not identified through its association with a parent entity.
