session vs database

[vbnick]

I am a developer for a very big B2B application. I would like to have some ideas from you people about session management. What I would like to ask you that i am making a shopping basket and i would like to save what it contains. When considering perfonmance, which one is better, sessions, cookies, or database?

memory (server session) is faster than file storage (client cookie, server db), but memory is very expensive to use and possibly impossible to serve with the traffic at hand.
