Separation of Concerns - Implementation

Implementation

All programming paradigms aid developers in the process of improving SoC. For example, object-oriented programming languages such as Delphi, C++, Java, and C# can separate concerns into objects, and a design pattern like MVC can separate content from presentation and the data-processing (model) from content. Service-oriented design can separate concerns into services. Procedural programming languages such as C and Pascal can separate concerns into procedures. Aspect-oriented programming languages can separate concerns into aspects and objects.

Separation of concerns is an important design principle in many other areas as well, such as urban planning, architecture and information design. The goal is to design systems so that functions can be optimized independently of other functions, so that failure of one function does not cause other functions to fail, and in general to make it easier to understand, design and manage complex interdependent systems. Common examples include using corridors to connect rooms rather than having rooms open directly into each other, and keeping the stove on one circuit and the lights on another.
