This project implements a microservice-based Order Management System (OMS) to streamline order fulfillment for an online store. Using Netflix Conductor, PostgreSQL, and Python, it demonstrates a minimal example of microservice workflows, offering insights into their structure and execution.
The workflow consists of five microservices executed sequentially:
| Microservice | Description |
|---|---|
| Order Acknowledgement Service | Receives and persists customer orders in the database, returning an acknowledgment. |
| Payment Processing Service | Processes payments and informs customers about payment status. |
| Stock and Inventory Service | Tracks product inventory, books stock for orders, and notifies customers about stock booking status. |
| Shipping Service | Coordinates shipment, generates tracking numbers, and updates delivery statuses. |
| Notification Service | Sends notifications to customers at various stages of order fulfillment. |
The OMS follows a linear workflow:
- Order acknowledgment
- Payment processing
- Stock booking
- Delivery scheduling
- Notifications
A shared database pattern is used with the following tables:
| Table | Purpose |
|---|---|
orders |
Stores order details and unique identifiers. |
payments |
Manages transactional data for payments. |
inventory |
Tracks product inventory levels. |
stock_bookings |
Allocates stock for orders. |
delivery_schedule |
Tracks delivery and shipment details. |
notifications |
Manages customer notifications. |
