I encountered a sentence
Database is nothing but an organized form of data [...].
and got confused by the part "nothing but".
- What is it used for and what meaning does it convey here?
How correct is it to start a formal definition with "nothing but"?
How is it different from the next quote?
Database is an organized form of data [...].
I've seen a few sentences with this structure before. They were pretty logical, rather informal, and, I guess, "nothing but" meant "only" there.
Thank you in advance.
