Surrogate keys have much meaning for users.
Answer: B
Correct answer: False
A surrogate key is an artificial identifier - typically a system-generated integer - with no relationship to the data it identifies, which is exactly the point: it never changes, it is short, and it is guaranteed unique. The cost is that it means nothing to a user, so a meaningful candidate key usually has to be kept alongside it and given a unique constraint.
