What is HLD and LLD in SDLC?
HLD stands for “high-level design” and would consist of laying out the overall architecture and high-level design of the solution at the level of applications, modules, classes, etc. LLD stands for “low-level design” and would consist of taking the HLD and turning it into code.

What is the difference between HLD and LLD?
The HLD is also known as macro-level or system design. It changes the business or client requirement into a High-Level Solution. The High-level design is created before the Low-Level Design. What is LLD? The LLD stands for Low-Level Design, in which the designer will focus on the components like a User interface (UI).
What is HLD (high level design)?
HLD or high level design is created initially during the Design journey of a Solution. It provides a high-level view of overall System setup describing the relationship of various systems and functions which combine to provide the expected solution.
What is low level design (LDD)?
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 full form of HLDD?
1. It stands for High-Level Design. It stands for Low-Level Design. 2. It is the general system design, which means it signifies the overall system design. It is like describing high-level design, which means it signifies the procedure of the component-level design.
