Dependency Inversion Principle: High-Level Modules Should Not Depend on Low-Level Modules

Dependency Inversion Principle: High-Level Modules Should Not Depend on Low-Level Modules

High-level modules should not depend on low-level modules. Both should depend on abstractions. This principle inverts traditional dependency structures, yet developers routinely create rigid architectures that violate it.

Interface Segregation Principle: No Client Should Be Forced to Depend on Unused Methods

Clients should not be forced to depend on interfaces they don't use. This principle prevents fat interfaces that burden implementers with unnecessary methods, yet developers routinely create bloated abstractions that violate it.

Liskov Substitution Principle: The Contract You Can't Break

Subtypes must be substitutable for their base types without breaking program correctness. This principle ensures inheritance hierarchies remain sound, yet developers routinely violate it with seemingly innocent design decisions.

Open-Closed Principle: Extending Without Breaking

Software entities should be open for extension but closed for modification. This principle promises flexibility without fragility, yet developers struggle with when to apply abstraction and when it becomes over-engineering.

Single Responsibility Principle: The Foundation of SOLID Design

A class should have only one reason to change. This simple statement forms the foundation of SOLID design, yet developers struggle with what constitutes a 'single responsibility' and when to split classes.
