High-Level Design (HLD)
High-Level Design (HLD) outlines the system architecture and overall structure of a software solution. It defines components, modules, data flow, technologies and their interactions. HLD focuses on scalability, performance and reliability, serving as a bridge between requirements and Low-Level Design. It’s essential for planning system-wide decisions.
System Design
System design is the process of defining the architecture, components, modules, interfaces and data flow of a system to meet specific requirements. It focuses on creating scalable, efficient and maintainable solutions, covering both high-level design (HLD) and low-level design (LLD). Essential for building reliable, high-performance software systems.
