Relations to Other Principles
Generalizations
- Low Coupling (LC): LC aims at reducing the dependencies to other modules. One way to do so is to only depend on abstractions. DIP is about this aspect.
Specializations
Contrary Principles
- More Is More Complex (MIMC): DIP demands introducing abstractions, especially abstract classes or interfaces.
Complementary Principles
- Model Principle (MP): DIP demands having abstractions. MP tells how these abstractions can look like.
