Description: Tight coupling is a design principle in software development that refers to the high dependency between components of a system. In this context, components are so interrelated that any change in one of them may require modifications in others. This contrasts with loose coupling, where components are more independent and can interact through well-defined interfaces. Tight coupling can lead to a less flexible and harder-to-maintain system, as interdependence can complicate understanding of the code and implementation of new functionalities. In general, tight coupling can manifest in architectures where services are closely integrated, making scalability and implementation of new features difficult. In terms of Clean Code, reducing tight coupling is promoted in favor of a cleaner and more maintainable design. Design patterns, such as the observer pattern or the strategy pattern, are used to encourage looser coupling, allowing components to interact in a more flexible and efficient manner. In summary, tight coupling is a critical concept in software design that affects maintainability, scalability, and code quality.
