HLD (High-Level Design) is an early phase in software development. It outlines the overall structure and functionality of a system.
Key Characteristics of HLD:
- Defines major components and their interactions
- Specifies system architecture
- Outlines data flow and storage
- Describes user interfaces at a high level
- Identifies key technologies and platforms
HLD Typically Includes:
- System architecture diagram
- Component descriptions
- Data models
- User interface mock-ups
- Technology stack overview
Benefits of HLD:
- Provides a blueprint for detailed design
- Facilitates communication among stakeholders
- Helps identify potential issues early
- Guides resource allocation and planning
- Serves as a reference for development teams
HLD is usually created after requirements gathering and before detailed design. It evolves as the project progresses and
