If you're new to the world of web development, it might help to have a bit of context on what Camping's "models" actually are. ActiveRecord is an abstraction of a database that's primarily developed for use in the Ruby on Rails framework, which you could argue Camping is to some extent a rebellion against.
In early web apps, people would manually embed SQL query strings in scripts and templates written for PHP, Perl, Python, etc. This approach has several problems, possibly most importantly: it's difficult to "scale" the functionality of a web app or make it more interactive, and it's vulnerable to attacks like "SQL" injection, where malicious input can have an undesirable effect on server-side behaviour. Most popular web frameworks use something called an "ORM", which is what ActiveRecord is - the data in the database is represented via "classes" and native objects in the code. Camping is somewhat uncommon as a lightweight, beginner-friendly framework that has a built-in ORM (though there's nothing forcing you from using its neat rendering and routing features without bothering with the Models, or from implementing your own "Models" atop files or a noSQL database.
