It really depends on the problem. Using a DH well also requires some expertise. I'm writing a small web app where users have a spaiic list of items. I started with a db but it's so much more complex than a simple file per user. Beside you have single big indexes for all the user data while there is a clear split of information between user. I didn't know how to handle hat efficiently. It turned back to one file per user with the content loaded and cached in memory.
