<p>[Problem] To resolve, with respect to conventional database accumulating methods, the issue of being able to accumulate only information about a store and additional information that combines information about products carried by the store and customer information registered at the store, and the issue of not being able to accumulate information about the customer other than that pertaining to that store or those products. [Solution] The present invention provides an aggregation server (4) between store servers (1) and advertisement servers (2). The aggregation server (4) accumulates information provided from the store servers (1) pertaining to product shipments, and advertisement information (2A) provided from the advertisement servers (2), and the advertisement information (2A) provided from the advertisement servers (2) is delivered to the customer (5) together with the product. When the customer (5) connects to another store server (3) on the basis of the advertisement information (2A), the customer information (5A) at the time of the connection to the other store server (3), advertisement information (5C), and purchase information (5B) for the shipped product, are accumulated, and when a product is purchased at that other store, purchase information (5D) for that purchased product is accumulated.</p> |
