Question chat application opinion

[cocol]

Hello.

i want to develop a chat application,but i want to develop the ability of private chat between 2 users.

multiple users chat is very simple,but private chat is very complex ,but if we use database it become simple and very flexible.
so i need your expert opinion before i go through to built this chat application.

should i use database or not? (related with performance).

thank you very much for your time.

If you need to store data in a central location then a database is the obvious choice.

thank you for your reply.
database is very flexible and it's "simple" to implement private chat between 2 users,but if we have hundreds of users and for each 2 users we have connection to the database to store and retrieve data, so maybe we affect the chat application performance,so the question is:
is there other way or idea to start build a private chat application between 2 users ,without using database?
because if we don't have other way,so the database is the only way.
thank you very much for your time.

I don't think that you really read what I posted. You may have looked at the words, but you didn't absorb the meaning.

The question is simple: do you need to store data in a central location? If you do then there isn't really a better option than using a database. If you don't then there's no need for a database. You tell us. What data do you need to store for a private chat?
