As the first step in mapping the project's architecture, we will begin by creating a UML component diagram. The main goal here is to identify and describe the structural connections between the various components that comprise our system.

A component is defined as an encapsulated standalone unit that constitutes an integral part of a system or a sub-system. Components communicate with each other by exposing and consuming one or several interfaces.

One key point of component-based design is that components should always be considered as abstract, logical entities that expose a particular behavior. This design approach is closely aligned with the SOLID principles and offers us the flexibility to freely change or even swap component implementations at any point throughout the project's development.
