DataRelation

[Tony Johansson]

Hello!

I can't understand what is this table DataRelation used for.
I mean as long as you have this DataTable I can't see any point in using
this DataRelation.

A DataRelation object is used to specify relations between DataTable
objects with a DataSet.

DataRelation is NOT A TABLE. It's a class. It's used to make a
relationship between columns in two tables.
DataTable in turn has a collection of DataRelation instances (in the
same way that it as a collection of DataRow objects) where it manage
the relationships of its columns with other tables/columns
