Low Level Design in short LLD is like detailing HLD means it refers to component-level design process. It describes detailed description of each and every module means it includes actual logic for every system component and it goes deep into each modules specification. It is also known as micro level/detailed design.
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 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.

Class diagrams with all the methods and relations between classes come under LLD. Program specs are covered under LLD. LLD describes each and every module in an elaborate manner so that the programmer can directly code the program based on it. There will be at least 1 document for each module.
What is a top level design?
Definition: In acquisition-oriented systems engineering, a top-level system design represents the envisioned implementation of a system in sufficient detail to support credible projections of cost, schedule, performance, evolution, and risk.
What is low level and high level document?
High Level Design is the general system design means it refers to the overall system design. Low Level Design is like detailing HLD means it refers to component-level design process. It is also known as macro level/system design. It is also known as micro level/detailed design.
Domain-Driven Design(DDD) is a collection of principles and patterns that help developers craft elegant object systems. Properly applied it can lead to software abstractions called domain models. These models encapsulate complex business logic, closing the gap between business reality and code.

What is high level design in ecommerce?
High-level design (HLD) explains the architecture that would be used to develop a system. The architecture diagram provides an overview of an entire system, identifying the main components that would be developed for the product and their interfaces.
Is construction phase called as coding phase?
3- Construction
This is also known as coding or building or developing phase. It is known as implementation phase at most of Software engineering blogs, while it may be correct from developers perspective not from the overall process perspective as we will see that the implementation phase has different activities.
