Purpose of High-Level Design

The purpose of this High-Level Design (HLD) is to add the necessary detailed description to represent a suitable model. This is designed to help with operational requirements and can be used as a reference manual for how the modules interact. Basically, HLD is a technical representation of functional requirements and the flow of information across assets or components.

What is High Level Design – Learn System Design

High-level design or HLD refers to the overall system, a design that consists description of the system architecture and design and is a generic system design that includes:

  • System architecture
  • Database design
  • Brief description of systems, services, platforms, and relationships among modules.

High-level design or HLD is also known as macro level designing.
