The of the Software Development Life Cycle (SDLC) is where business requirements are transformed into a technical blueprint . This phase is split into two critical stages: High-Level Design (HLD) and Low-Level Design (LLD) . High-Level Design (HLD): The Macro View : Typically created by Solution Architects or senior

HLD serves as the architectural roadmap, defining "what" the system will do and how its major parts connect. Responsibility : Created by Designers and Developers

: Overall system architecture, technology stack, and major modules (e.g., Database, UI, Security).

LLD provides the detailed "how" of the system, acting as a direct guide for developers to write code.
