Is flat file faster than database?
4 Answers. The flat file may be a bit faster, but it will end up being more buggy in the long run, because instead of just doing a SELECT * FROM messages WHERE room=nnn AND ID > yyy , you will have to load the file, parse it, scan each row for the message ID, go to the right message, and then read it out.
Why are databases better than flat files?
