Erlang Dict. Is it stored in memory or on Disk

I'm an erlang newbie so I apologize if this question is incredibly dumb. I'm working with erlang:dict() to build something that refers to user information as in Kevin Smith's , Erlang in Practice examples.

I'd like to know if dict records are stored in memory. Is it something like Ruby's Hash data structure.

Are records actually stored in a dict in production systems when they need to be referred to beyond a system restart? I need to store a user Uid, Nickname and a Password for every user who registers on my system but I need the information to be durable, much like how XMPP handles registered users. Should I be using Mnesia in this case?

Would really appreciate your help.

Thank you.

Dicts will not survive restarts. You should use mnesia, dets or some other database system of your choice depending on your needs. I guess mnesia is fine for ids, unames and passwords.
