Dependency Inversion

Dependency Inversion is a design principle in software development that promotes loose coupling between components. It suggests that high-level modules (which make decisions) should not depend on low-level modules (which perform tasks), but both should rely on abstractions like interfaces. This way, changes to low-level modules don’t directly affect high-level ones, making the system more flexible and easier to maintain. Essentially, it inverts the traditional dependency flow, emphasizing that abstraction controls the dependencies rather than concrete implementations.
