Data Entity Revisions for an Offline Database

Abstract:

A method for processing user orders for products may include receiving an order for an order quantity of the product from a user computing device, determining that the order management system cannot communicate with the inventory management system to reserve the order quantity of the product, retrieving a last known inventory quantity of the product, retrieving an offline demand quantity for the product, transmitting a confirmation of the order to the user computing device when the sum of the order quantity and the offline demand quantity of the product is less than or equal to the last known inventory quantity of the product, and transmitting a denial of the order to the user computing device when the sum of the order quantity and the offline demand quantity of the product is greater than the last known inventory quantity of the product.
