SOLID Principles
Five object-oriented design principles for creating maintainable and scalable software.
Also: SOLID
Definition
SOLID is an acronym for five foundational object-oriented programming principles: Single Responsibility (a class has one job), Open/Closed (open for extension, closed for modification), Liskov Substitution (subclasses should be substitutable for base classes), Interface Segregation (clients should not depend on unused interfaces), and Dependency Inversion (depend on abstractions, not concretions). Following SOLID principles leads to loosely coupled, testable, and maintainable codebases that accommodate change gracefully.
Example
“Applying the Single Responsibility Principle, a developer separates user authentication logic from user profile management into distinct classes, making each easier to test and modify independently.”
