Relational database design question - Surrogate-key or Natural-key?

Question

Which one is the best practice and Why?

a) Type Table, Surrogate/Artificial Key

Foreign key is from user.type to type.i

Answer 1

I prefer to use the surrogate key. It is often people will identity and use the natural key which will be fine for a while, until they decide they want to change the value. Then problems start.
