Architectural flexibility refers to the ability of a system to be easily adapted and modified without breaking its functionality. This flexibility supports low coupling because it allows system components to be easily replaced or modified without disrupting the entire system.
In a system with high coupling, changes in one component affect all other components of the system, which makes it difficult to modify or add new features. In a flexible system, however, components are designed with well-defined interfaces, which allows for easier replacement or modification of individual components without affecting the overall functioning of the system.
For example, a system that uses plugins or modules can be modified by adding, removing or replacing modules without changing the core architecture of the system. This flexibility allows for a modular design that supports low coupling, as each module can be modified independently of other modules, reducing the dependencies among modules and promoting a low-coupling architecture.
Overall, architectural flexibility supports low coupling by allowing for easier modification and evolution of the system, reducing dependencies between components, and promoting a modular design that supports system adaptability and extensibility.
