Background
Inversion of control is not a new term in computer science. Martin Fowler traces the etymology of the phrase back to 1988. Dependency Injection is a specific type of IoC using contextualized lookup The use of a service locator is considered using the same design pattern. In an article by Loek Bergman it is presented as an architectural principle.
In an article by Robert C. Martin the dependency inversion principle and abstraction by layering come together. His reason to use the term "inversion" is in comparison with traditional software development methods. He describes the uncoupling of services by the abstraction of layers, when he is talking about dependency inversion. The principle is used to find out where system borders are in the design of the abstraction layers.
Inversion of control is highly associated with dependency injection and the dependency inversion principle. Dependency injection is the main method to implement inversion of control.
