Tightly Coupled Systems
Tightly coupled systems are software architectures where components are highly interdependent, with strong dependencies and shared resources. Changes in one component often require modifications in others, leading to reduced modularity and flexibility. This approach contrasts with loosely coupled systems, where components interact through well-defined interfaces with minimal dependencies.
Developers should understand tightly coupled systems to recognize their pitfalls, such as difficulty in maintenance, testing, and scalability, which are common in legacy or monolithic applications. Learning this concept helps in refactoring efforts and designing more modular, maintainable systems, especially when transitioning to microservices or distributed architectures. It's crucial for identifying technical debt and improving system resilience.
