I’m planning on using Ajax with my web application, but as I’m novice and don’t have much experience I wonder when ajax should and when should not be used? I plan to code with jQuery/php if it makes any difference.

AJAX is most useful when your application wants to present a data set to its user in many different ways. Sorting and filtering and in general interacting with a data set feels best when there are no delays waiting for a server to redraw the pages and send them over the network. It’s also nice for handling display of new data arriving on the server — the client can just pull the data that is new and merge it into the data set on the client rather than requiring a whole new page draw including all the data you’ve seen before. This can save quite a bit of bandwidth.
AJAX should not be used when you need to keep your application simple, though technologies like jquery are making the client side easier and easier to get right. But in general I would say that if the information you’re delivering is pretty static — it only needs to be viewed in one or two ways, then an AJAX approach may just be overengineering.
