Architectural flexibility refers to the ability of a system to adapt to changing needs and requirements over time. This adaptability can support system cohesion in several ways:
1. Modular architecture: An architecture that is designed with modularity in mind allows for the system to be broken down into smaller components that are easier to understand, maintain and update. This modular approach enables each component to have its own cohesive functionality, which in turn helps to improve the overall cohesion of the system.
2. Separation of concerns: A system that is designed with a clear separation of concerns helps to maintain system cohesion. For example, a system that separates its data storage from its business logic allows for a clear separation of concerns and improves the overall cohesion of the system.
3. Reduced dependencies: An architecture that reduces dependencies between components helps to minimize the impact of changes made to one component on other components of the system. This reduces the risk of breaking cohesion in the system due to a change in one component.
4. Encapsulation: Encapsulation allows for individual components of the system to be protected from external interference, ensuring that components maintain their own internal coherence. This helps to improve the overall cohesion of the system.
Overall, architectural flexibility supports system cohesion by enabling the system to adapt to changing needs and requirements while maintaining the coherence of its individual components.
