The Command Query Responsibility Segregation (CQRS) patten is a design pattern that focuses on splitting software architecture into two clear responsibilities. The first is Commands that change the state of the system and the second is Queries that return the current state.
The Mediator patten, implemented using the .NET library MediatR, is another design pattern used to reduced dependency complexity between objects and facilitate loose coupling of code.
In this talk we will learn more about each of these patterns, and how when combined, can be used as the foundation for building powerful enterprise applications that are easy to maintain.
