I would like to create a sample flash application and put it on the web. I already know how to do this with PHP but want to try it with flash. All I want is name and address with a save button. Also do I have to use XML to send that data back and forth or can I have flash on the server side send the data directly to the postgresql or mysql server?

Any tips, thoughts, or links if you can find any would also be appreciated.

Basically I want to come as close to client server development but over the web as possible with only my web server connecting to the sql database behind a fire-wall. Avoiding use of XML if practical.

Thank You :D
