Software design is crucial for a codebase to be less cursed and more composable, akin to a form of sorcery.Clean code without good software design is like IKEA furniture without instructions, ready to collapse.Software design challenges often manifest as 'design debt boss fights,' impacting code maintainability and scalability.Understanding software design principles is essential to building systems that are modular, reusable, and scalable.Software design involves breaking down logic into components with clear boundaries and responsibilities.Components in software design are self-contained modules that perform specific tasks efficiently and independently.Effective software design emphasizes low coupling (less dependence between components) and high cohesion (parts working well together).Architecture patterns like MVC, Layered, Hexagonal, and Microservices offer guidelines for structuring applications effectively.Iterative design processes and tools like diagrams, visualizations, and code refactoring aid in improving software design.Learning software design involves practice, refactoring code, studying good codebases, experimenting with architectures, and sharing knowledge.Software design is not just about writing code; it's a mindset shift towards building robust, scalable, and maintainable systems.
