I have a mySQL database that is only slowing updating its data, for two fields only, into the admin table at backend of my website. Some fields even take as long as 30 minutes to be updated into the admin table, as my last programmer used cron job to comb the mySQL database a scheduled intervals. I was thinking of using AJAX programming to make the update HAPPEN IMMEDIATELY, ie. as soon as data from the mySQL database changes, the admin table (visible to admin officers) in the backend of my website will also change IMMEDIATELY TO REFLECT THE SAME VALUES.
(Note you can't make the admin table capture data immediately from frontend - if you were thinking of that - as the data going into the mySQL database comes from emails.) So extract from the mySQL database which is getting the data from emails coming in.
