I admittedly come from an Ektron background for professional development but for personal reasons DNN is very attractive. But maybe because of my past experience, I'm having a tough time wrapping my head around the concept of pages in DNN. I think of a page as an aspx page (for example) that I create. In ektron, I create a master page, create my pages that will use it, and add ektron controls for the parts that need to be managed by users. The data driven parts are managed by controls or something else that I  create.

In DNN, I keep seeing that pages are created in the tool, and aren't pages in the sense that I'm used to thinking about it. Is this a system where I need to create a bunch of modules (user controls) all allow content editors to drag them to page? Right now, I'm not sure how to even start. Using DNN, do you typically start with a web project and create pages or are you just adding modules to an DNN install?

A high level answer is fine. I think I'm confusing myself because I came into this experienced with another tool.
