Drupal isn't a content management system. It's an application development platform that happens to ship with a great CMS as it's default implementation. Look at any chart comparing features of development frameworks and you'll see user management and authentication, forms management and validation, data storage, database migrations, internationalization and translation, MVC model with flexible templating, unit testing, and caching. Sounds a lot like Drupal. We'll look at why Drupal is an ideal application development platform for apps beyond content management, talk about where Drupal can improve in these areas, and look at an example application.
