ASP.Net Core Web API - CQRS and MediatR Pattern

In this video , we are going to know a brief introduction to the CQRS pattern, and how the .NET library MediatR helps us build software.
The MediatR library was worked to work with two essential programming design designs: CQRS and the Mediator design.
In conventional information models, where peruses and composes are in synchronization sometimes with data sets, it turns out to be important to keep up the "Corrosive" properties relating to the information. Here comes the part of CQRS which means "Order Query Responsibility Segregation" which indicates that distinctive information models ought to be utilized for refreshing the data set and read from the data set. Order and Query are two tasks that represent read and composes individually.
MediatR : It’s an object that encapsulates how objects interact. So it can obviously handle passing on “messages” between objects.It promotes loose coupling by not having objects refer to each other, but instead to the mediator. So they pass the messages to the mediator, who will pass it on to the right person.
