I feel somewhat competent as a Flash designer for front end, eye candy stuff. But I know absolutely nothing about back end stuff. I'd like to learn how to create a web application for a client that would store information (client names, the vehicle they drive, the vehicle mileage, last time it was serviced, etc.) and let me retrieve it quickly on any computer connected to the internet.
Is that something that can be done in Actionscript, or do I need to learn something like SQL? (I don't even know what that is, is that a language, an ap, or what?)
Can anyone recommend where one should start on this road, a good how-to book for example?
Thanks for any info!
