How does the inventory system interact with the store system?
The store system sends a query to the inventory database whenever a customer selects a book. The inventory system then checks if the item is in stock and sends a response back. If available, the transaction continues; otherwise, the system notifies the customer. This interaction prevents overselling and ensures that the system maintains accurate records of available book stock.

What role does the payment gateway play in this diagram?
The payment gateway is an external entity that manages the secure exchange of funds. It receives payment details from the store system and verifies the transaction with the bank. Once the payment is approved, it sends a confirmation back to the store. This allows the system to finalize the order and update the inventory records to reflect the sale.
