Design Patterns: S.O.L.I.D. Dependency Inversion Principle

Avoiding Dependencies Between Layers As part of the S.O.L.I.D. design principles, the Dependency Inversion Principle (DIP) provides guidance for ensuring layers within the application avoid unnecessary dependencies from coupling. DIP ensures each layer’s modules remain independent of one another and should depend on abstractions instead of concrete details, increasing usability and flexibility to change. In…

Design Patterns: S.O.L.I.D. Interface Segregation Principle

Providing Focused Behaviors for Classes As part of the S.O.L.I.D. design principles, the Interface Segregation Principle (ISP) supports other S.O.L.I.D. principles in providing classes with focused behavior by ensuring interfaces inherited by classes remain lean and focused on specific behaviors. To illustrate ISP, I’ll use examples from the Single Responsibility Principle (SRP) article. I’ll begin…

Design Patterns: S.O.L.I.D. Overview

Ensuring software remains understandable, flexible, and maintainable In response to common design difficulties inherit within many software systems, a series of design patterns were integrated together to form the acronym, S.O.L.I.D., which representing a specific principle. In addition to producing programming code and architecture which is understandable, flexible, and maintainable, it avoids code which is…
