Software Design Principles (SDP)

Software Development Principles — it is a number of specific rules and recommendations.

Design principles do not provide implementation and not bound to any programming language. They are generic.

• Keep it Simple(,) Stupid / Keep it Short & Simple - KISS
• Don't repeat yourself - DRY
• SOLID
  1. Single responsibility principle - SRP - class should do only one task
  2. Open/closed principle - OCP — class should be extended not modified
  3. Liskov substitution principle - LSP - derived classes must be substitutable for their base classes
  4. Interface segregation principle - ISP - interfaces should be fine-grained
  5. Dependency-inversion principle - DIP - depend on abstractions, not on concretions
• Command Query Responsibility Segregation CQRS
• You Aren’t Gonna Need It - YAGNI
• Avoid Premature Optimization
• Separation of Concerns
• Encapsulate What Changes
• Favor Composition over Inheritance
• Separate Data fron Logic
• Extract when it Grows
• Inversion of Control (IoC)
