Salesperson # Order # Order Dt Order Total

Solution
in the table [salesperson] detrmines [order] , and [order] determines [ order Dt] and [orderDt]
determines [order total] and [order] determines [order total] vice versa.we have transitive
functional dependency, and this structure does not satisfy third normal form.
To bring this table to third normal form, we split the table into two as follows:
137
Now all non-key attributes are fully functional dependent only on the primary key.
Salesperson # Order # Order Total
