Hey. I just have a few general questions about AJAX, as I am thinking about adding a little to my site. So here they are.

I have all my stuff stored in a database, is it easy to update info from a database and not have to reload the page. i.e click a link and it updates a section with the new database stuff. If it is, do you have any example code you could throw my way? Thanks.

EDIT: Also, is it possible to keep all this AJAX (the stuff mentioned above) on the same page, so I don't have to include external files. I've seen some things that might have worked, but they had to post stuff to another file.

Um... Just 1 I guess. :p Thanks guys.
