I am busy with an employee record project and would like to know if it is possible at all to have my project update the database via links?

Let me explain. 

Within the editing of an employee I would like to add a menu with a couple of links. These links will only be used by our employers. The will (if the above mentioned is possible) be able to click on the link "dismissed", then that should update the database by means of changing the field "Employed\_Status" to "0".

I could really use the help from professionals as I am still at the "Very beginner" stage. Thanks in advance.
