design

Guidelines for requirements analysis, design principles, architecture, and security.

| Single Responsibility | A class/module should have one reason to change | Class doing too many things | | Open/Closed | Open for extension, closed for modification | Modifying existing code for new features | | Liskov Substitution | Subtypes must be substitutable for base types | Overridden methods breaking contracts |

| Interface Segregation | Many specific interfaces > one general interface | Clients forced to depend on unused methods | | Dependency Inversion | Depend on abstractions, not concretions | High-level modules importing low-level details |

تصميم أنظمة برمجية بمبادئ SOLID، DRY/KISS/YAGNI، والأمان حسب التصميم. يُستخدم عند تخطيط الميزات، أو تحليل المتطلبات، أو تعريف البنية، أو اتخاذ القرارات المعمارية. المصدر: knoopx/pi.
