What are good ways to design a web application? Do you, for example, begin with a wire-frame of the front-end and work your way back to the database schema? The reverse? Figure out both ends and work towards the center?

I start with a working prototype, which I find I can often knock together in a couple of hours using Django. Having a functional (albeit buggy, ugly and insecure) prototype makes it much easier for me to start to reason about the larger application. There’s not much point in coming up with a comprehensive architecture plan only to find out you’re building the wrong thing!
