Key software principles include abstraction, loose coupling, high cohesion, DRY, YAGNI, KISS, SOLID principles, modularity, separation of concerns, and design patterns like CQRS, dependency injection, and domain events, promoting maintainable, scalable, and robust applications.

Design and architectural patterns are fundamental concepts in software engineering that help developers create robust, maintainable, and scalable applications. These patterns provide proven solutions to common problems encountered in software design and architecture. In this page, we’ll explore some of the most important patterns.

Let’s explore some fundamental principles that guide software engineering practices.

1. 📦 Abstraction

Hiding complexity by exposing only necessary details while concealing the implementation specifics.

Abstraction is a fundamental principle in software design that involves creating simplified interfaces to complex systems. By hiding implementation details and exposing only what’s necessary, abstraction helps manage complexity and makes systems easier to understand and maintain.

Key Characteristics

• 🎯 Information Hiding: Internal complexities are concealed from external users
• 🔄 Interface-Based Design: Clear separation between what a component does and not how it does it
• 📦 Modularity: Systems are broken down into self-contained, manageable units
• 🔌 Encapsulation: Related data and behaviors are bundled together
• 🎨 Abstraction Levels: Different layers of abstraction for different users and purposes
