System and analysis design

1. System design

System design involves creating the architecture of a software system to meet specified requirements. This process encompasses defining the system's components, their interactions, and how they will work together to achieve the desired functionalities. Here’s a comprehensive overview of system design:

 1. High-Level Design (HLD)

 a. System Architecture

- Definition: Outlining the overall structure of the system, including hardware and software components.

- Components: Identifying major system components and their relationships.

- Architecture Styles: Choosing appropriate architecture patterns such as client-server, microservices, monolithic, or distributed systems.

b. Data Flow Diagrams (DFD)

• Purpose: Visual representation of data movement through
