Dependency Inversion Principle
Software Engineering · Last updated: July 30, 2026 · How this entry was written
Definition: The dependency inversion principle is a design principle that states high-level modules should not depend on low-level modules; both should depend on abstractions. It decouples software components and makes the system more flexible and testable.
Example in context
“By applying the dependency inversion principle, we made the payment processing module depend on an abstraction rather than a concrete database driver.”
“Bağımlılığın ters çevrilmesi ilkesini uygulayarak, ödeme işleme modülünün somut bir veritabanı sürücüsü yerine bir soyutlamaya bağımlı olmasını sağladık.”
Where engineers use it
Used during code reviews and architecture discussions, an engineer cites the dependency inversion principle to justify introducing interfaces and dependency injection containers for better separation of concerns.
Synonyms: DIP
Practice: can you use “Dependency Inversion Principle” at work?
During a code review, a junior developer has a high-level service directly instantiating a low-level repository class. Explain how applying the dependency inversion principle would improve the design and testability.
