METHOD AND DEVICE FOR GATHERING INFORMATION, PROGRAM, AND MEDIUM

PROBLEM TO BE SOLVED: To solve such problem that though effective marketing can be done by grasping customer information showing what business consumables a customer buys by using what device, but it becomes difficult to gather customer information by salesmen if the sale of business consumables using the Internet spreads. SOLUTION: A customer code and an article code are extracted from order data (S81) and business consumables relating to an ordered article are picked up on the basis of order reception probability correlation analytic data and a condition 1 (S82). When the business consumables are picked up, the picked-up business consumables are narrowed down on the basis of expected sale analytic data by articles and a condition 2 (S84). When there are picked-up business consumables (S85), information on a product which use the business consumables is obtained from a product information database (S86) and when data relating to the obtained product information are not recorded in a 'purchase or specification article name' field of a customer information database (S87), order reception confirmation mail to which an information providing request regarding the product information is added is issued (S88).
