An order management system in electronic communication with a database may be configured to manage concurrent update requests for the order data stored in the database. In particular, the order management system may be configured to receive two or more order modification requests, determine that the second order modification request includes one or more aspects that conflict with the modified order and includes one or more aspects that do not conflict with the modified order, send a notification to the second user, wherein the notification includes the one or more aspects that conflict with the modified order, and modify the modified order according to the one or more aspects of the second order modification request that do not conflict with the modified order to create a second modified order.

Methods and system for concurrent updates of a customer order

A method for operating a database and a cache of at least a portion of the database may include receiving a plurality of read requests to read a data entity from the database and counting respective quantities of the requests serviced from the database and from the cache. The method may further include receiving a write request to alter the data entity in the database and determining whether to update the cache to reflect the alteration to the data entity in the write request according to the quantity of the requests serviced from the database and the quantity of the requests serviced from the cache. In an embodiment, the method further includes causing the cache to be updated when a ratio of the quantity of the requests serviced from the database to the quantity of the requests serviced from the cache exceeds a predetermined threshold.

Cache coherency engine

Receiving and processing user orders may include receiving an order for an order quantity of a product from a user computing device, retrieving a threshold inventory quantity of the product, retrieving a last known inventory quantity of the product, comparing the threshold inventory quantity with the difference between the last known inventory quantity and the order quantity, performing an asynchronous reservation of the quantity of the product when the threshold inventory quantity is less than the difference between the last known inventory quantity and the order quantity, and performing a synchronous reservation of the quantity of the product when the threshold inventory quantity is greater than the difference between the last known inventory quantity and the order quantity.
