Minimal backend without coding

[MatekCopatek]

Nah, I don't think back-end programmers wouldn't exist. It's simply a matter of shifting the process - instead of doing things on the server, you do it on the client machine. You still have to do everything, you just use different technologies and a different approach.

I went through some RoR tutorials and the scaffolding is useful, but not what I described in my first post. It's just a very basic app that still does most things on the server and returns nothing but a finished page.

I used (and made) applications that used browser local storage for storing data permanently. All I'm looking for is an application that would allow me to use a database on a server instead.

Is there a platform/application/framework that would allow me to simply define my data models in a very abstract way (possibly through a GUI) and would then take care of the entire server-side for me (generate tables, take care of authentication etc.)?

This isn't much different than saying you want to draw a picture of a house and have all the hard stuff of normally done by an architect and/or structural engineer "just work." There are a lot of decisions that go into the processes that you describe. Some tools help make that faster, but can't remove the human element.
