Separation of Concerns (SoC)

Introduction

Separation of Concerns (SoC) is a design principle that suggests dividing a software application into distinct sections, where each section addresses a separate concern or responsibility. By isolating concerns, you make the system easier to develop, maintain, and scale.

Benefits

Improves modularity and reusability.
Facilitates easier testing and debugging.
Encourages clear boundaries between components.

Example

In a web application, consider using the Model-View-Controller (MVC) pattern:

The Model handles the data and business logic.
The View is responsible for displaying information to the user.
The Controller acts as an intermediary between the Model and View, managing user interactions.

This separation ensures that changes in one part (e.g., the UI) do not affect other parts (e.g., business logic).

Takeaway

By adhering to the SoC principle, you create a system with clear boundaries, making it easier to understand, maintain, and extend.
