The principle states:<br /> <br /> * A. High-level modules should not depend on low-level modules. Both should depend on abstractions.<br /> * B. Abstractions should not depend on details. Details should depend on [[Abstraction (software engineering)|abstractions]].<br /> <br /> The principle inverts the way some people may think about object-oriented design, dictating that both high- and low-level objects must depend on the same abstraction.<br /> <br /> == See also ==<br /> <br /> * [[Abstraction (software engineering)]]<br /> * [[Adapter pattern]]<br /> * [[Coupling (computer programming)]]<br /> * [[Creational pattern]]<br /> * [[Dependency Injection]]<br /> * [[Design by contract]]<br /> * [[Interface]]<br /> * [[Inversion of Control]]<br /> * [[Modular programming]]<br /> * [[Object-oriented programming]]<br /> * [[Plug-in (computing)]]<br /> * [[Service locator pattern]]<br /> * [[SOLID]] – the &quot;D&quot; in &quot;SOLID&quot; stands for the dependency inversion principle<br /> <br /> == External links ==<br /> <br /> * [https://en.wikipedia.org/wiki/Dependency_inversion_principle Dependency inversion principle] @ Wikipedia<br /> <br /> <br /> [[Category:Computer programming]]</div>
