SOLID: Dependency Inversion Principle
Explore the Dependency Inversion Principle (DIP) which promotes high-level modules depending on abstractions rather than details. Learn how this principle reduces coupling by introducing abstraction layers, making designs easier to expand and maintain. Understand its benefits through examples and class diagrams to improve software flexibility and stability in object-oriented design.
We'll cover the following...
Introduction
The Dependency Inversion Principle (DIP) states that high-level modules should not depend on low-level modules, but rather both should depend on abstractions. The abstractions should not depend on details. Instead, the details should depend on abstractions.
In many cases, thinking about the interaction between modules as an abstract concept allows the linking of components to be reduced without the need for more coding patterns to be implemented. This allows for a functional scheme with reduced implementation and allows the system to be more flexible. ...
