Checkout Component Diagram

This component diagram shows an ecommerce checkout as a small set of clear responsibilities. The checkout user interface hands the request to an orchestrator. That coordinator calls separate cart, pricing, payment, inventory and order components, while the order component triggers receipt generation after completion. The drawing is deliberately at component level: it does not describe database tables, API paths or a particular payment provider. It is useful for a design review because it makes the workflow owner and collaboration points visible. Add fraud screening, promotions, tax calculation, inventory reservation or asynchronous notifications when those functions are present in the product.

שאלות נפוצות

Why use a checkout orchestrator?

It coordinates the checkout workflow without making the user interface responsible for business operations.

Is payment part of the order component?

It can be, but separating it makes payment-specific integration and failure handling clearer.

What does the receipt component do?

It creates the customer-facing confirmation after an order is completed.
