AJAX wouldn't help with that because the client isn't online. I can think of a few approaches:
1) Have a last modified user/time on each row and show the user a list of changes since last login made by the admin.
2) Set up an e-mail notification when the admin changes things.
3) Manually have the admin tell the client when something has changed.

YOu can just do a query when the user logs in to see what records have changed. The alternative is to store changes as they happen in a log table, but that's not necessary.
