What should a HLD contain?
High-level design document This document includes a high-level architecture diagram depicting the structure of the system, such as the hardware, database architecture, application architecture (layers), application flow (navigation), security architecture and technology architecture.
What is LLD testing?
Low-level design (LLD) is a component-level design process that follows a step-by-step refinement process. This process can be used for designing data structures, required software architecture, source code and ultimately, performance algorithms.
What is the difference between LLD and HLD?
The HLD changes the client or business requirement into a high-level solution. The LLD changes the high-level solution to a comprehensive solution.
What is LLD or detailed design?
LLD, also known as a detailed design, is used to design internals of the individual modules identified during HLD i.e. data structures and algorithms of the modules are designed and documented.

- Explore some open-source projects and try to understand the best practices.
What is a HLD document?
The HLD documentation presents the structure of the system, such as the database architecture, application architecture (layers), application flow (Navigation), and technology architecture. The HLD uses non-technical to mildly-technical terms which should be understandable to the administrators of the system.
