The first half of the title refers to the influential “Design Patterns: Elements of Reusable Object-Oriented Software”. The second half refers to “AntiPatterns: Refactoring Software, Architectures, and Projects in Crisis”. In either case, selected best-/worst-practices in software architecture are examined.
