FIG. 3 illustrates a method of exchanging information among a user terminal, a controller of a server, a first database and a second database, and the connections of each node according to an exemplary embodiment of the present invention. 1. Operation method.

In operation 305, as in operation 205 described above, the controller may obtain information about the master item and request information from the first database based on the information about the master item.

In operation 310, as in operation 210 described above, the controller may receive from the first database one of the sub-items comprising the main item and one or more sub-items grouped together with the main item based on information about the main item. Information about the group.

In operation 315, the controller may request information from the second database based on the group information received from the first database. The second database may contain promotional information corresponding to group information comprising a main item and one or more sub-items grouped together with the main item. In an exemplary embodiment, the promotion information may include discount information applicable when the main item and one or more sub-items are purchased together, a discount period and discount provider information.

In operation 320, the controller may receive first promotional information corresponding to the group information from the second database based on the group information. For example, group information may include a monitor as a main item, and a keyboard, a monitor cable, and a monitor stand as sub-items. The second database may contain promotional information, such as discount amount information that may be offered when a user purchases a monitor together with at least one of a keyboard, a monitor cable, and a monitor stand as sub-items, and may Contains discount information for each combination including all or some of the main item and one or more sub-items. In response to the query of the group information by the controller, the second database can output and provide the first promotional information corresponding to the group information to the controller.

In operation 325, the controller may provide the user terminal with the first page further including the first promotional information. In an exemplary embodiment, the first page may further include detailed information about the main item and the first promotional information together with the main item and one or more sub-items grouped together with the main item. The first page may be a detail page that displays detailed information about the main item, and the first page may include discount information applicable to the user when the user purchases the main item and one or more sub-items together. Thus, the server allows the user to easily grasp the main item by displaying the promotional information corresponding to the group information on the first page together with the group information including the main item and one or more sub-items grouped together with the main item Correspondence with sub-items and discount information, and can induce users to purchase the main item and sub-items together at a discounted price.

In an exemplary embodiment, at least some of the one or more sub-items and the main item may be grouped and displayed in a first area on the first page, and the first area may further include first promotional information.

In operation 330, as in operation 220 described above, the controller may obtain, from the user terminal, a selected group of sub-items and a main item selected according to a first user input corresponding to a first page. Information.

In operation 335, the controller may request information from the second database based on the obtained information about the selected group. In one exemplary embodiment, the information about the selected group may include all main items and one or more sub-items included in the group information, but in another exemplary embodiment, the information about the selected information may include Information about a group of main items and one or more child items. Thus, since the sub-items included in the group information displayed on the first page may be different from the sub-items selected by a user to add to a shopping cart or to pay for, except as in operation 315 based on the group information In addition to requesting information from the secondary database, it is also necessary to request information from the secondary database based on the information of the group selected in this stage. In addition, the pieces of information corresponding to the pieces of information stored in the second database may be different according to time, and since the first promotional information received from the second database based on the group information in operation 320 may be different Promotional information received from the second database based on the information on the group selected at this stage after a certain period of time, so information from the second database needs to be requested based on the information on the group selected at this stage.

In operation 340, the controller may receive second promotional information corresponding to the information about the selected group from the second database based on the information about the selected group. For example, a first page may contain a monitor as the main item, and a keyboard and a monitor cable as sub-items grouped with the monitor, and among them, a user may select only the monitor monitor and keyboard instead of a monitor cable. In this case, the information on the selected group includes the monitor as the main item and the keyboard as a child item, and the controller may request promotional information from the second database based on the information on the selected group including the monitor and the keyboard . Based on the information about the selected set, the controller may receive from the second database, based on the information about the selected set, second promotional information applicable when purchasing the monitor and keyboard together. For example, when the monitor, keyboard, and monitor cable are purchased together, the keyboard is 20% off the original price, but when only the monitor and keyboard are purchased together, the keyboard is 10% off the original price. Thus, the second database may contain promotional information corresponding to a plurality of subgroups of information comprising some elements of the group information, and by receiving promotional information from the second database based on the information of the group determined according to a user selection Information, which identifies information about discounted prices based on child items selected by the user.

In operation 345, the controller may provide the user terminal with a second page further including second promotional information. In an exemplary embodiment, the user may be provided with a second page containing information for a group selected according to a second user input. In an exemplary embodiment, the second page may further include second promotional information corresponding to the selected set of information together with the selected set of information. For example, the second page may be a shopping cart page or a payment page, which includes information of a selected group including a main item and at least one sub-item among the main items and sub-items displayed on the first page. The second page may contain discount information applicable to the user when the user purchases together the main item and child items included in the selected set of information. Thus, in the case of entering a second page by selecting some of the main item and one or more sub-items grouped and displayed on the first page, the main item and selected sub-items may be grouped and displayed on the second page , and may display discount information corresponding to information about the selected group together. Therefore, the user can more intuitively understand the group information including the main item and one or more sub-items and the promotional information corresponding to the group information by increasing the relevance among the plurality of pages. This can improve the user experience and induce the user to purchase sub-items together at a discounted price when the user purchases the main item.

In an exemplary embodiment, the server may identify an ungrouped item among items included in the second page, and when the ungrouped item corresponds to an item included in one or more sub-items included in the group information For a first sub-item, the server may request information from the second database based on the first sub-item and the selected set of information, and receive alternative promotional information from the second database corresponding to the first sub-item and the selected set of information , and the second page can further include alternate promotions. For example, when the main item and one or more sub-items contained in the selected group information on the shopping cart page or payment page are displayed on a specific area, they are not grouped together with the main item or one or more sub-items items can be displayed outside the specified area. When the server identifies ungrouped items as described above, the server can identify whether the ungrouped item corresponds to one or one of the sub-items included in the group information including the main item. For example, when the ungrouped item is an item of the same type as the first sub-item grouped with the main item currently displayed on the second page, if the user uses the first sub-item grouped with the main item Instead of ungrouped items, the user can be provided with a promotional offer corresponding to the group information.

In the above exemplary embodiment, if the ungrouped item is an item of the same type as the first sub-item grouped with the main item, a promotion from the second database may be requested based on the first sub-item and the selected group information information, alternative promotional information corresponding to the information of the first sub-item and the selected group may be received from the second database, and the alternative promotional information may additionally be displayed in the second page. For example, if the price of an ungrouped item is ₩ 10,000, if the ungrouped item is replaced by a first child item that is an item of the same type, the promotion applies and the price of the first child item can be discounted to ₩ 8,000. Thus, on the second page, the server can display alternative promotional information that the user can additionally obtain by replacing the ungrouped item with the first child item of the same type, and thus, the server can direct the user to click a Purchase the same product at a greater discount to improve user satisfaction and user experience.
