System Design

This article explores the Command Query Responsibility Segregation (CQRS) pattern and how it can be used to design a system. CQRS separates the read and write operations of a data store into two separate components: the command side and the query side. This allows you to optimize the read and write operations independently and improve the performance, scalability, and consistency of the system.
