SA Rating is a rating system based on the traveler's experiences using Sentiment Analysis methods. This project is done in fulfillment of the award of a Master’s Degree in Information Systems at Kobe Institute of Computing.

This POS system, designed with a microservices architecture, consists of nine key services: Identity, Catalog, Order, Purchase, Inventory, Payment, Customer, Billing, and Financial. Each service has distinct responsibilities ranging from user management (Identity Service), managing item metadata (Catalog Service), handling orders and purchases (Order and Purchase Services), managing inventory (Inventory Service), processing payments (Payment Service), managing customer details (Customer Service), issuing invoices (Billing Service), to overseeing financial health (Financial Service). The system also includes a web-based POS Console that consumes all these services' APIs. The design of the system ensures scalability and separation of concerns, allowing each service to evolve independently, and improving overall system robustness.
