I've developed a rather extensive Data Portal, with lots of (mostly statistical) country data covering the globe. Now, I would like to develop a small iPhone app to make this realm of data accessible to mobile users too.
I know there is the possibility of a "real" App and then these "web app frameworks" (iWebKit, WebApp.Net) one can use to ease the way.
I imagine two different thematic approaches: a) a country profile for a given (selected) country; b) a graph or table for a selected variable and selected countries.
Now, I am not very familiar with AJAX, although it seems to me to be a great solution to my challenge. On the other side, I see that I can use my "normal" SQL requests to dig into the Postgres database.
What approach would you recommend based on your experiences?
