How does separation of concerns work?
In computer science, separation of concerns (SoC) is a design principle for separating a computer program into distinct sections such that each section addresses a separate concern. When concerns are well-separated, there are more opportunities for module upgrade, reuse, and independent development.
Why we use MVVM pattern in Android?
MVVM is one of the architectural patterns which enhances separation of concerns, it allows separating the user interface logic from the business (or the back-end) logic. Finally, the view role in this pattern is to observe (or subscribe to) a ViewModel observable to get data in order to update UI elements accordingly.
Which is an example of the separation of concerns?
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.
What does separation of concerns mean in programming?
Separation of concerns results in more degrees of freedom for some aspect of the program’s design, deployment, or usage. Common among these is increased freedom for simplification and maintenance of code.
Why are modules a form of separation of concerns?
Modules can also expose different versions of an interface, which increases the freedom to upgrade a complex system in piecemeal fashion without interim loss of functionality. Separation of concerns is a form of abstraction.
Why is separation of concerns important in Normalized Systems?
In Normalized Systems separation of concerns is one of the four guiding principles. Adhering to this principle is one of the tools that helps reduce the combinatorial effects that, over time, get introduced in software that is being maintained. In Normalized Systems separation of concerns is actively supported by the tools.
