when an update is made to the database; update the information on ALL user's screens with the new information.

Like for instance, person A updates their information, and they hit the submit button.

Person B is just looking at their screen, and when Person A clicks to update their info, Person B will automatically see it without having to refresh their screen.

It's an automatic push of the information.

I have been doing some research and have been seeing mention of using JSON, but trying to find the exact functions to use...

Thanks,
