CoClasses that implement IRelationshipClass2

CoClasses and Classes	Description
AttributedRelationshipClass	AttributedRelationshipClass Object.
MemoryRelationshipClass	A relationship class object the is stored in memory.
RelationshipClass	RelationshipClass Object.

Remarks

The IRelationshipClass2 interface was added to provide a method to get matching objects.

An AttributedRelationshipClass is a special kind of relationship class and is also a kind of table known as the relationship table. For non-attributed relationship classes, the relationships are stored with the objects themselves in the foreign key values. For attributed relationship classes, the relationships are defined by the objects in conjunction with the rows in the relationship table.

A good way of testing whether you have an AttributedRelationshipClass object is as follows.

If TypeOf pRelClass Is ITable Then Debug.Print
  "Attributed Relationship Class"
End If
