High-Level Design (HLD): What It Covers and a Practical Example in C#

    When embarking on a software project, a well-thought-out High-Level Design (HLD) is crucial to guide development and ensure a scalable and maintainable system. It’s the bridge between abstract requirements and detailed implementation. But what exactly does HLD include, and how do you create one? In this blog, we’ll break down the components of HLD, provide a real-world example, and explore how to represent them in C#. What is High-Level Design (HLD)? HLD provides a blueprint of the system architecture . It defines the structure, components, and interactions at a macro level, focusing on "what" the system should do rather than "how" it does it. What HLD Includes System Architecture : The overall structure of the system, including its major components and their relationships. Diagrams like component diagrams or architecture flow diagrams are often used. Modules and Subsystems : A breakdown of the system into modules or subsystems, each responsible for specific fu...
