System Design
System Design is the process of defining the architecture, components, and data flow of a system to meet business and technical requirements.
HLD vs. LLD
| Aspect | High-Level Design (HLD) | Low-Level Design (LLD) |
|---|---|---|
| Focus | Overall system structure | Detailed component design |
| Audience | Architects, stakeholders | Developers, engineers |
| Granularity | Broad, conceptual | Specific, technical |
| Output | Diagrams, architecture docs | Class diagrams, pseudocode |
Both HLD and LLD are crucial for building scalable and efficient systems. One provides direction, the other ensures precision.
