Good question actually. I guess it's mainly to give people another option. This was inspired by my research into the SqlConnection object.
However, when trying to reproduce SQL Server relations in a dataset (for the next article in the series) I found that the "ForeignKeys" collection did not even include the columns involved.
BTW, there is a great stairway series on SSC by Phil Factor about the metadata.
