Systems and methods for recommending electronic devices based on user purchase habits

摘要

Identification information related to a device may be received that includes user information and device information. Based on the user information, a user entry corresponding to the user information may be located in a database of user records. It may be determined that the device information is not found in the user entry. A plurality of sales attributes may be determined in response. Those may include at least one of (1) a release date of the device and a purchase date indicating when the user purchased the device, and (2) a release price of the device and a current price of the device at the purchase date. Based on the information, a purchase metric may be computed and the device information stored in the previously purchased device field of the entry. Based on the purchase metric, a purchase metric threshold may be generated for recommending another device to the user.
