I am looking into learning some new programs. I am hoping to develop an app for the iPad to collect surveys and dump the data into a database on a server. I know very little right now about this since all my experience is using horrible ms access. I have only PC's currently. I can probably pick up a MBP if needed though. What is a good relational database that I should look at for developing the back-end database and what is a good place to start reading about developing iPad apps and forms and sdk's? Thanks a lot.
