The application architecture for Tweety will have a RESTful API backend and a model-view-viewmodel (MVVM) frontend. MVVM is a design pattern used to enable two-way data binding between the view and the model so that one changes when the other does. Angular is a very famous framework that conforms to the MVVM design pattern, which allows highly responsive frontend applications that efficiently update when data from the server changes or a user interacts with the application. Apart from this, Angular provides routing, dependency injection, components, templates, and so on to enable flexible, modular development.

The Tweety application will have the user interface (UI) implemented using Angular Material, which is a module provided out of the box to simplify UI development using custom tags and themes.
