Its principle states: High-level modules should not depend on low-level modules, both should depend on abstractions. Abstractions should not depend upon details. Details should depend upon abstractions. Dependency Inversion Principle is often …

In software design, this is usually a danger associated with procedural programming or frequent, …

Buzzword Buster – Macaroni Code

Definition: You have Macaroni code when your application is chopped up into many little pieces and it’s difficult to see the big picture which may exist only in your (or someone else’s!) head. In software design, you can often end up with Macaroni code when you overuse/misuse/abuse abstractions, and it’s one of the main dangers …
