Separation of Concerns is a design principle in software development that encourages dividing a program 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 code. By isolating different aspects of a program, developers can work on one part without affecting others. This principle is commonly applied in various fields, including web development and software engineering. For example, in web applications, the user interface, business logic, and data management can be separated into different layers, allowing for more organized and efficient development processes.
