> From any HTML (or XHTML, PHP) page, query the database without reloading the current page or navigating away. Using AJAX call from JQuery and PHP at the backend, create a streamlined system that takes in a user's input and instantly validates it with entries in the database. If found to be duplicate, instantly shows error while the user is still typing. Thus, creating a very interactive interface design and friendly for the end-users.
