Please take a look the link below :

As you see BTC - USD price is updating every some seconds in that web site.
I want to do same job on my web site with two points :
- Update price label in every some seconds & show it to user.
- In every update of price label save the new price to my database.
Imagine i have 1000 users.
So what is the best method to do this job and how can do that?
How can i create a relation between server side (save to database) & client side (update label)?
