What’s wrong with Northwind

Nearly every developer knows Microsoft’s sample database Northwind. Any change on Northwind can be realized like absence of Nancy Davalo’s picture. But non of us have looked the indexes of Northwind tables. Every table’s indexes are duplicated because 2 developers who created the indexes, did it separately. From this event we can understand that if we will create any type of index we have to look it up if it exists or not.
