The dependency inversion principle was postulated by Robert C. Martin and described in several publications including the paper Object Oriented Design Quality Metrics: an analysis of dependencies, [6] an article appearing in the C++ Report in June 1996 entitled The Dependency Inversion Principle, [7] and the books Agile Software Development ...

Dependency inversion principle, which can be thought of as applying the adapter pattern, when the high-level class defines its own (adapter) interface to the low-level module (implemented by an adaptee class). Ports and adapters architecture; Shim; Wrapper function; Wrapper library
Dependency injection is often used to keep code in-line with the dependency inversion principle. [ 6 ] [ 7 ] In statically typed languages using dependency injection means that a client only needs to declare the interfaces of the services it uses, rather than their concrete implementations, making it easier to change which services are used at ...
The dependency cannot be substituted, or its "signature" changed, without requiring a change to the dependent class. Loose coupling occurs when the dependent class contains a pointer only to an interface, which can then be implemented by one or many concrete classes. This is known as dependency inversion. The dependent class's dependency is to ...
In software engineering, inversion of control (IoC) is a design principle in which custom-written portions of a computer program receive the flow of control from an external source (e.g. a framework). The term "inversion" is historical: a software architecture with this design "inverts" control as compared to procedural programming.

It decomposes further the application core into several concentric rings using inversion of control. [8] The clean architecture proposed by Robert C. Martin in 2012 combines the principles of the hexagonal architecture, the onion architecture and several other variants. It provides additional levels of detail of the component, which are ...
