I think that comment is badly worded. Creating a database
index may involve sorting at some point, but that's irrelevant.
It's called "indexing" by analogy with indexing a book -- i.e.
creating a data structure allowing fast access to a data item
given a key. I think this usage of the term is much more widely
understood than just in the database field, or even the whole
computer field.

Why do you think that document has the word "Index" in its
title... :-)
