mrh-jishan/bookstore-cqrs-example

This system is a distributed bookstore application built on a CQRS (Command Query Responsibility Segregation) architecture, separating command and query models. It manages three primary business contexts: a product catalog for browsing books, a shopping cart for managing user selections, and an order processing system that handles order placement, activation, and publisher fee tracking. The architecture leverages domain events and sagas to coordinate state changes across these contexts, supported by in-memory persistence and RESTful APIs for both user interaction and administrative monitoring.
