        new DataTableMappingCollection();
    mappings.Add("Categories","DataCategories");
    mappings.Add("Orders","DataOrders");
    mappings.Add("Products","DataProducts");
    string message = "TableMappings:\n";
    for(int i=0;i < mappings.Count;i++)
    {
        message += i.ToString() + " "
            + mappings[i].ToString() + "\n";
    }
    Console.WriteLine(message);
}

Public Sub CreateTableMappings()
    Dim mappings As New DataTableMappingCollection()
    mappings.Add("Categories", "DataCategories")
    mappings.Add("Orders", "DataOrders")
    mappings.Add("Products", "DataProducts")
    Dim message As String = "TableMappings:" + ControlChars.Cr
    Dim i As Integer
    For i = 0 To mappings.Count - 1
        message &= i.ToString() & " " & mappings(i).ToString() _
