Why Clean Architecture is Popular: Understanding Coupling and Cohesion

👍Clean architecture is popular because it solves the problem of highly coupled systems that are difficult to change.

💡Clean architecture separates technical concerns and isolates the core domain, allowing for better manageability and maintainability.

🔍Context matters when considering clean architecture. It may not be necessary for small apps or systems with low coupling.

🔌Understanding coupling and cohesion is essential in deciding whether to apply clean architecture to a system.

🧩Cohesion, the grouping of related functionality, should be considered alongside coupling when designing software systems.

When is clean architecture necessary?

—Clean architecture is necessary for large systems with high coupling or complex business logic where separation of concerns and maintainability are important.

Is clean architecture suitable for small apps?

—Clean architecture may not be necessary for small apps with low coupling or simple functionality. Simple CRUD apps may not benefit from the additional layers and complexity introduced by clean architecture.

What is the difference between coupling and cohesion?

—Coupling refers to the dependency and interaction between software modules, while cohesion refers to the logical grouping and organization of related functionality.

Why is cohesion important in software design?

—Cohesion is important because it allows for better organization, maintainability, and reusability of code. It helps ensure that related functionality is grouped together, making the system easier to understand and modify.

What are the benefits of clean architecture?

—Clean architecture provides separation of concerns, easier maintainability, and flexibility to change specific parts of the system without affecting others. It also promotes good software design practices and ensures the core domain is isolated and free from external dependencies.
