Coupling in software engineering refers to the degree of interdependence between software modules. Low coupling means that modules are independent and changes in one module have minimal impact on others, while high coupling indicates strong interconnections between modules. Reducing coupling is important for creating modular, maintainable, and scalable systems. Techniques such as interface-based design, dependency injection, and service-oriented architecture help in achieving low coupling, making the system easier to understand, test, and modify.
Why is low coupling desirable in software design?
Low coupling is desirable because it makes modules independent, reducing the impact of changes and making the system easier to understand, test, and modify.
What techniques can be used to reduce coupling?
Techniques to reduce coupling include interface-based design, dependency injection, and service-oriented architecture, which promote modularity and independence between modules.
How does coupling affect system maintainability?
Coupling affects system maintainability by influencing how easily changes can be made to the system. Low coupling enhances maintainability by reducing dependencies and making modules more self-contained.
