A DataRelationCollection object enables navigation between related parent/child DataTable objects.
You create a DataRelationCollection object by defining it as a property of either the DataSet or the DataTable, instead of by directly using a constructor. (Use the Relations property of the DataSet, or the ParentRelations property of the DataTable.)
To access the collection, use the Relations property of the DataSet object.
As soon as the collection exists you can manage the objects it contains by using methods such as Add, Clear, and Remove.
