Thanks Fred for your detailed answer. Now, I realize where I stand. About the "carts" table I'm assuming that at a particular time more than one customer will be shopping so this "carts" table will hold items of each customer with a reference to a session id given to each customer. Each details for each customer will be retrieved and deleted with the help of this session info. Anyway, now I think I can reach somewhere.. thnx very much. -- Posted via http://www.ruby-forum.com/.
