    <p>You are way, way over-thinking things. Not that that's bad at all - it's great you want to learn the innards of how everything fits together and works, but Rails handles the vast majority of stuff like this for you.</p> <p>For development purposes you are most likely going to use the Ruby webrick "server", which you can run from your applications home directory by doing: ruby script/server</p> <p>Now, whenever you go to your application, which is by default going to be running at: <a href="http://localhost:3000/" rel="noreferrer">http://localhost:3000/</a> , this server will process your requests and return the html for the appropriate view. If you have your app created and have a database set up, going to the url I mentioned will show you a "welcome aboard" message from Rails, letting you know everything is up and running. Later on when you push your app into production you'll be using the Apache server, but still, you won't have to worry about the things you mentioned in your question.</p> <p>It is entirely possible to use Rails without a database, check out config/environment.rb:</p> <pre><code># Skip frameworks you're not going to use. To use Rails without a database, # you must remove the Active Record framework. # config.frameworks -= [ :active_record, :active_resource, :action_mailer ] </code></pre> <p>Just uncomment that last line and make sure you leave active_record in it.</p> <p>I think what is going to help you best overcome your confusion is to research how Rails routing works, which is controlled by the config/routes.rb file. I think this will help you understand how Rails accepts and reacts to incoming requests.</p> <p>And Rails is actually perfect for building little sandbox websites to play around with - once you get over the initial learning curve you can get stuff up and running very fast.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
