Separation of Concerns is a design principle used in software development and other fields. It involves breaking a complex system into distinct sections, each addressing a specific concern or functionality. This approach helps to manage complexity, making it easier to develop, maintain, and understand the system. By isolating different aspects, such as user interface, business logic, and data management, developers can work on each part independently. This leads to improved collaboration and reduces the risk of errors. Common implementations of this principle can be seen in frameworks like MVC (Model-View-Controller) and microservices architecture.
