Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic commerce system and method for trading goods, a server, a client and a program, and more particularly to electronically trading valuable goods by using a server and a client in combination. Electronic commerce system and method, server,
Regarding clients and programs.

2. Description of the Related Art Communication technology using computers has become widespread, and for example, various transactions and contracts have been conducted using the Internet in which computers are connected to each other by a network. A typical example of this is the WWW (World Wide) which is the Internet and its usage method.
Electronic commerce (EC: Elec) that sells and sells products using the Web
tronic Commerce) system.

There are various types of electronic commerce systems. For example, a user who purchases a product uses a WWW browser or the like to operate an interface on an electronic commerce site to select or purchase a product, or a data format of a purchase order such as business-to-business transaction is defined. A typical format is to send and receive order form data via a network.

In such an electronic commerce system, a product to be traded may be a composite product which is a combination of a plurality of products which are independently distributed. For example, when trying to cook a dish,
Therefore, it is necessary to purchase a combination of products as a plurality of ingredients. In addition, when purchasing system furniture, or purchasing a computer and peripheral devices for image input / output and related software for image processing all together for one purpose, the purchase is a composite product.

[0005] When conducting electronic commerce of such complex products, there are roughly two types of commerce. The purchaser considers the combination of each product and issues a purchase request for each of the composing products, and the retailer decides the "possible combination type" for the purchase, and the purchaser targets the combination. This is a second mode for selecting individual products (including parts. The same applies hereinafter) to be

In the first form, the purchaser as a user needs to individually order each single product constituting the composite product. In the present specification, a product is a product that is distributed independently of a single product. Even parts can be a single product if they are independently traded and purchased. Also, a single product does not necessarily mean a minimum unit product. Any product that is a subordinate concept that constitutes a composite product may be used. For example, there is a meal (combined product) called "ramen rice" that has economic value by combining ramen and rice. In this case, the single products that compose the ramen rice (composite product) are ramen and rice, but the ramen is further divided into several products as food ingredients, and the ramen itself has a character as a composite product.

Regarding the first form used conventionally, WWW
A specific example of electronic commerce using is given below. The purchaser sequentially specifies the products to be purchased and registers these in a place called a basket for storing the products to be purchased. At this time, all single products that make up the composite product are registered in the basket. After that, by collectively ordering these single products, electronic commerce of the composite products is performed. In the above example, the purchaser imagines a meal called "ramen rice" and electronically orders "ramen" and "rice" individually.

FIG. 17 shows an example of a second form of electronic commerce system. This electronic commerce system 10
0 is the device 101 on the product purchaser side as a client
And a merchandise seller side device 102 as a server. Although not shown, the WWW (Worl
d Wide Web) and other networks exist. Also,
In the figure, one product purchaser side device 101 and one product seller side device 102 are shown for simplification. The product purchaser-side device 101 includes a user input / output unit 111 for inputting / outputting various information. Product seller side device 1
02 includes a seller-side composite product information processing unit 121 that processes composite product information and a product order processing unit 122 that performs product order processing. The seller-side composite product information processing means 121 handles one kind of composite product information 123 based on one seller.

Here, the composite product information 123 is composed of single product information a ₁ , a ₂ , a ₃ , ... For each single product constituting a specific composite product. These single product information a ₁ , a ₂ , a ₃ , ... Are product type information 141 indicating the type of each single product.
And product information 142 such as a specific product name (or identifier), price, size, and the like.

In the electronic commerce system according to the second embodiment shown in FIG. 17, the seller side defines in advance the combination of the commodity types of the complex commodity, and the commodity seller side device 10
From the 1 type of composite product information 123 prepared in 2,
Based on this, it was necessary to select each single product needed. Therefore, the purchaser communicates with the purchaser-side composite information processing means 121 in the product seller-side device 102 through the user input / output means 111, and the composite product information 12
Edit 3. In the case of the electronic commerce system using WWW, specifically, the composite product information 123 including an input form listing the components of the composite product is prepared on the site of the product seller device 102. The buyer takes steps to select each single item required on the seller's site and then place the actual order. Taking the above-mentioned “ramen rice” as an example, the definition of “ramen rice” itself is provided by the merchandise seller side device 102 side. Therefore, if the buyer likes the composite product and has “rice” at hand, he / she will order only “ramen” based on the composite product information 123 and eat “ramen rice”.

In the first form that can be adopted in the electronic commerce system described above, a user who is a purchaser considers a set of a plurality of predetermined single products as one composite product at his or her own discretion. . Then, a plurality of single products that make up the composite product are selected one by one, and they are collectively purchased. In the second mode, an operation system is prepared in advance so that the shop side sells a plurality of products as one product. The purchaser can purchase the product group arranged as a composite product at the store side as it is, but can also change some of the constituent products or change the combination to a desired combination.

For example, Japanese Unexamined Patent Publication No. 2001-306958 describes a technique for selecting and purchasing foodstuffs according to the menu. In this technique, when the purchaser selects a menu of dishes to be made, a list of ingredients necessary to make the dishes is displayed. The purchaser can select a desired food item from the displayed options for each food item included in the list and collectively purchase the food item.

[0013]

However, there are problems in each of the first and second modes that can be adopted in the electronic commerce system described above. First, problems with the first embodiment will be described. The problem with the first form is that the combination of parts that are the constituent elements of the composite product is
This is something that the buyer himself must consider. The reason is that, in many cases, the seller does not define a complex product, and the operating system is such that all must be purchased as a single part. Defining the composition of a composite product is necessary to determine the excess or deficiency of the parts that make up the composite product. It is difficult to purchase a composite product without such a definition unless the buyer has deep knowledge of the product. For this reason, there is a problem in that unnecessary or duplicate single products are purchased, or the purchased single product does not satisfy the function as a composite product and it takes time to use the composite product. .

The second form that can be adopted in the electronic commerce system solves the problem of the first form in that the structure of the complex product is defined. However,
The second form also has some problems. The first problem is that even if an attempt is made to obtain information about individual single products that make up a composite product, it cannot be referred from the electronic commerce system. Further, if each electronic commerce system is different, it is not possible to share information about a composite product of this kind and a single product as a component between them.

This is because the processing for recognizing the information about each product as a component of the composite product is locally performed by the program inside the system of each seller. That is, the configuration information itself of the complex product exists only inside the program of the specific system. For this reason, unless the program itself is configured to retrieve the configuration information of the complex product independently,
These pieces of configuration information cannot be extracted and used independently. This makes it impossible for the purchaser to manage the composition information of the complex product in its own way. Therefore, only when the user purchases the complex product, the single product based on the complex product information is added to the system of the store based on the complex product information. It is not possible to realize a system that transmits information about. Also,
It is also impossible to purchase these single products by referring to the same complex product information in the electronic commerce system by different sellers.

A second problem with the second mode is that it is not possible to purchase a composite product that extends over a plurality of sellers at once. This is the same as the cause of the first problem, and the process for recognizing the information of each single product as a component of the composite product is locally performed by a program inside the system of each seller. This is because For this reason, unless all the single commodities composing the composite merchandise are related to the composite merchandise sold by one seller in the electronic commerce system, they cannot be collectively purchased as a composite merchandise. As described above as the first mode that has been conventionally adopted in the electronic commerce system, such a complex product needs to be individually purchased by the purchaser.

The third problem of the second form adopted in the electronic commerce system is due to the first problem based on the second form, and the composition information of the composite product is referred to as the composite product. Separately, it is not possible to define additional information that is separately cut out and used effectively as the configuration information of the complex product. This is the same as the reason for the first problem of the second mode. That is, the configuration information of the complex product cannot be separated from the processing system independently. Even with the conventional technology, if there is a technique to utilize the configuration information separately, addition such as setting only some of the single products that make up the composite product as fixed values or limiting the service connection destination for single product search When information is provided, various effective uses such as an advertisement effect of selling a single product can be achieved, but in the second conventional form, the composite product information itself cannot be used in the form as described above.

The fourth problem of the second form adopted in the electronic commerce system is due to the first problem and the third problem of the second form, and the composite product information itself. The point is that there is no mechanism for inviting purchasing behavior of complex products. The conventional electronic commerce system does not have a mechanism for distributing composite product information as information independent of the seller's sales system, and a mechanism for promoting the purchase of composite products exists only in the seller system. As described above, the composite product information to which appropriate additional attribute information is added has a utility as a product advertisement, but the utility cannot be obtained by a system having no information distribution mechanism.

Therefore, an object of the present invention is to make it possible for a purchaser to easily purchase a complex product having a unique value by combining a plurality of products, and to promote an increase in sales opportunities of this type of complex product. To provide a business transaction system and method, a server, a client, and a program.
