One real-world example of the saga pattern in a microservices architecture is an online shopping application.
In this application, the system is divided into multiple microservices, each of which has its own database.
For example, there might be a shopping cart microservice that maintains a database of the items in each user's shopping cart, an order processing microservice that maintains a database of the orders that have been placed, and a payment processing microservice that maintains a database of the payments that have been processed.
