DataSet Relationships

Been working quite heavily with strongly typed datasets at the moment. I keep getting asked the same question about the difference between relationship types. So in a simple nutshell;

Imagine two tables "Father" and "Son" with a relationship between the two.

Relationship type - Relation Only. Will generate intellisense method Son.FatherRow

Relationship type - Foreign Key Constraint Only. Will enforce relational integrity. No intellisense method as in Relation Only.

Relationship type - Both Relation and Foreign Key Constraint. Provides both intellisense method and relational integrity
