High level design (Architectural design) … provides an overview of the system. Example: Infotainment-System (focus on media and navigation only)

This structural pattern increases the functionality of a class. Looks similar to a proxy, but it gets the object injected

This behavioral pattern is used to let objects behave differently based on their current state.

This structural pattern controls the access to a class. Looks similar to a decorator, but it instantiates the object by

This structural pattern translates one class interface into another. This is a class adapter, but there also exists an object

This creational pattern assures that just one object can get instantiated of that class.

Concrete Factory … is a class that creates objects without exposing the instantiation logic. Abstract Factory … is a class

The purpose of that behavioral design pattern is to add a new operation without adding it to the existing object

As the name of this creational design pattern already shows dependencies are getting injected (as parameter) instead of creating them
