What is an advantage of placing computations in SQL views?
Answer: C
Correct answer: To accomplish both of the above.
Both reasons matter and the second is the stronger. Putting the expression in the view saves every user from writing it, and more importantly ensures they all use the same one - so a margin or a total means the same thing wherever it is quoted, and a change to the definition takes effect everywhere at once.
