There are two kinds of system design: High-Level Design (HLD) and Low-Level Design (LLD). On the infographic, you'll discover the system design term and the difference between high-level and low-level design. The terms are about system architecture which is a basis when creating software. To put it simply, high-level design is in charge of the overall plan of the system, whereas low-level design is concerned with its specific components. LLD is a practical extension of HLD.

1. What is System Design?
Why Not Go Straight to an LLD?
High-Level design is done by a solution
architect to specify the general design
of a system or application. Purpose?
To transform the requirements of a client
to a high-level solution. It's a no-code
stage which is rather about technical
documentation and diagrams.
Low-Level design is more about diving into
details. You take the parts of high-level
design and start going into specifying how
they would be composed and coded.
HLD (high-level design)
It includes decision tables, decision trees,
flow diagrams, flow charts, and a data
dictionary.
It includes:
LLD (low-level design)
High-Level design is the overall system
design. It shows us the general design.
Low-Level design is a detail-level process
High-Level means macro-rank. HLD overall
description/architecture of the application.
Low-Level means micro-rank. It is a
detailed description of each and every
module.
HLD is architect’s work. LLD is done by designers and developers.
High-Level design collects the design
team, review team, and client team.
Low-Level design participants bring
together the design team, operation team,
and coders.
The first thing created is high-level design. Low-Level design is done only after HLD
step.
System design
more about architecture.
is the process of designing any software application .
It's called "design" but actually is
We're building a new project's flow.
(thanks, cap)
Is it necessary to dedicate so much effort before the general plan is not approved?
We think you know the answer.
The HLD describes the big picture LLD focuses on details
, while the in the technical
and implementation sphere.
