Patterns used¶ ↑

• Model-View-Controller : The application follows the classical web implementation of the MVC architectural pattern. The models (.rb files) and views (.erb files) are stored in the corresponding models and views directory. The controllers are the (.rb files) inside of controllers directory and the app_router.rb

• Adapter : The model game.rb is an adapter to use the player.rb and quiz.rb inside the controller quiz_app.rb.

• Domain-Specific Language : The app_router.rb file consists of a series of Sinatra routes. Sinatra is a DSL for creating web applications in Ruby.

• Command : The controllers quiz_app.rb and manger_app.rb contain the concrete commands to each route declared in the app_router.rb , so in this way all the web routes invoke the corresponding command to do a concrete action.
