Code Smell 319 - Hardcoded Stateless Properties

The article discusses the concept of coupling in software design, highlighting it as a fundamental issue that impacts maintainability and scalability. Here are some key points from the discussion:

1. Definition of Coupling:

   • Coupling refers to how closely different parts of a system interact with each other.
   • High coupling means components depend heavily on one another, making them difficult to change independently.

2. Types of Coupling:

   • Data coupling: Components exchange data through parameters or return values.
   • Control coupling: One component controls the flow of execution in another.
   • Content coupling: Direct access to internal variables of other modules.
   • Stamp coupling: Passing complex data structures between components, leading to tight integration.

3. Impact on Software Design:

   • Tight coupling leads to rigid systems that are hard to modify or extend without breaking existing functionality.
   • Loose coupling promotes modularity and separation of concerns, making code easier to understand and maintain.

4. Strategies for Reducing Coupling:

   • Use interfaces and abstract classes to define contracts between components.
   • Favor composition over inheritance to create more flexible designs.
   • Employ design patterns like Dependency Injection (DI) and Inversion of Control
