I have heard that AJAX is a way to get a page to refresh when a MySQL db has changed. Basically we have a log (that several users at a time could be looking at), when data is submitted it posts to the MySQL db. Instead of having the page auto-refresh every 2 minutes or so, it would be nice if it would just refresh when a change is detected in the db. This would also cut down on the chances that data is missed due to inopportune refreshing/submitting. Pretty much a novice so any help on where to start would be appreciated.
