Chain of Responsibility (CoR)

The Chain of Responsibility (CoR) is a design pattern in software development where a request is passed along a chain of objects until one handles it. Each object in the chain has the opportunity to process or forward the request. This approach promotes flexibility and separation of concerns, allowing different parts of a system to manage different aspects of a request without tightly coupling components. It is often used to implement event handling, validation, or access control, ensuring responsibilities are distributed efficiently across relevant objects.
