I've developped a few web applications and forms along the years, but never could I get something together as quick as I did when I decided to try MS Access, for a prototype app. E.g. I've used Django, yes I can create forms pretty quick, but with Access with _no programming_ and 2-3 hours of familiarization I could put up forms with create/edit/delete functionality in something like 30 minutes, along with the underlying schema.
I haven't touched it since I created that prototype, but I was left wondering what's the equivalent in the webapp world, for the basic CRUD use-case.
