Object-Oriented Design

SOLID principles, 319

Over the past several years, a number of object-oriented design principles have emerged. Many of these design principles are embodied within design patterns. The SOLID design principles espoused by Uncle Bob are prime examples. Further analysis of the GOF patterns reveals that many of them adhere to these principles.

For all the knowledge shared, and advancements made, that help guide object-oriented development, creating very large software systems is still inherently difficult. These large systems are still difficult to maintain, extend, and manage. The current principles and patterns of object-oriented development fail in helping manage the complexity of large software systems because they address a different problem. They help address problems related to logical design but do not help address the challenges of physical design.
