Application builders in the sky
Do-it-yourself online tools are quickly moving beyond the creation of forms and spreadsheets to database-driven Web appsFollow @peterwayner
Programmers older than 12 who still pine for the days when code was written in ASCII and stored in files will be happy to know that some sites are still wedded to traditional ways. AppJet is a nice IDE for Web applications that lets you write the code in your browser. The entire type-test-debug cycle occurs on the client.
The irony goes even deeper, because AppJet's framework and simplicity mean you're building an entire Web site out of a simple file. It's a funny conceit that probably can't outlast the ability of humans to make things more complicated than they need to be. But it illustrates just how much can be done with these simple applications.
