Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a net transaction method using a user terminal device, a plurality of trader terminal devices, and an intermediary terminal device connected by a communication network, a data processing method and system thereof, an intermediary terminal device thereof, The present invention relates to a data processing method and an information storage medium in which a program for a computer of an intermediary terminal device is stored as software.

[0002]

2. Description of the Related Art At present, the Internet, which is a communication network, has become widespread to the general level, and a net transaction in which a general user and a seller perform data communication through the Internet to establish and sell goods is becoming common.

[0003] In such online sales, it is common for a general user to access a sales terminal device of a dealer from a user terminal device via the Internet, and designate and purchase a product presented by the user. However, since used cars, passports, real estate, and the like are expensive and have many uncertainties, it is preferable for a general user to make a plurality of dealers create quotes and compare them.

[0004] Therefore, a net transaction for realizing this is also proposed as a reverse auction, and is disclosed in US Pat. No. 5,794,207 and US Pat. No. 5,897,620.
No. 5,797,127, JP-A-11-6
No. 6168, and the like.

In the data processing system 10 disclosed in US Pat. No. 5,794,207, as shown in FIG.
A user terminal device 11, which is composed of a personal computer or the like, a mediation terminal device 12, and a plurality of trader terminal devices 13 are connected by a communication network 14 such as the Internet, and perform data communication with each other.

First, a condition input screen in which a plurality of types of purchase conditions relating to the purchase of a product are input as data is registered in the mediation terminal device 12, and the mediation terminal device 12 requests a communication request from the user terminal device 11. When data is received,
A condition input screen for data transmission by the mediation terminal device 12 is displayed and output on the user terminal device 11.

Therefore, when a general user inputs a plurality of types of purchase conditions on the condition input screen, the data is transmitted from the user terminal device 11 to the plurality of dealer terminal devices 13 via the mediation terminal device 12. The seller considers the purchase conditions displayed and output on the dealer terminal device 13 of each of the sellers, and creates a sales quote.

[0008] When the sales quotes created by the plurality of dealers are input to the dealer terminal device 13, the plurality of sales quotes are transmitted to the mediation terminal device 12. Therefore, the broker compares and compares the plurality of sales quotes displayed and output on the mediation terminal device 12, selects the best sales quote, and transmits the data from the mediation terminal device 12 to the user terminal device 11. User terminal device 11
Displays the optimal sales quote.

In the data processing system 10 disclosed in Japanese Patent Laid-Open No. 11-66168, as shown in FIG. 7, sales quotes created by a plurality of dealers are transmitted from the dealer terminal device 13 to the mediation terminal device 12. Since the data is directly transmitted to the user terminal device 11 without intervention, the general user can compare and evaluate a plurality of sales quotes by himself.

[0010]

[0006] In the above-described reverse auction online transaction, even when purchasing a product having many uncertainties, such as a used car, a passport, and a real estate, a general user who purchases the product is not allowed. When a general user inputs desired purchase conditions on the condition input screen, the data is transmitted to a plurality of dealers.

[0011] However, on the condition input screen actually used, desired purchase conditions are input to a plurality of types of items prepared in advance, but sales which completely satisfy all of the purchase conditions desired by general users. The number of cases where a seller can create a quotation is small, and the case where a general user also considers a priority order or a subtraction condition for a plurality of types of purchase conditions is large.

[0012] For example, when a general user is considering a real estate lease contract, desired purchase conditions are generated for layout, rent, age, and the like. However, the building age may be slightly longer than desired, but the rent should not be higher than desired, such as taking into account priorities, and if the layout is wider than desired, the building age may be longer than desired.
It is common to take into account such deduction conditions.

However, it is extremely difficult to reflect such considerations of general users in online transactions. Even on the current online transaction condition input screen, there is generally a column for entering special notes such as requests, but the priority order and the deduction condition considered by general users are accurately input with text data Doing so is not preferable because the operation is complicated.

Further, the content of data input as text data in the entry field of the special instructions as described above needs to be visually judged by an intermediary agent or a distributor, and is mechanically determined by the intermediary terminal device or the agent terminal device. Since data cannot be processed, the efficiency of online transactions is hindered.

The present invention has been made in view of the above-mentioned problems, and when a general user inputs desired purchase conditions on a condition input screen prepared by an intermediary, a plurality of types of purchase conditions are added together with a plurality of types of purchase conditions. Trading method, data processing method and system, intermediary terminal device, data processing method, computer program of intermediary terminal device as software, which can also input data such as priority of purchase condition and mutual relation such as subtraction condition It is an object to provide at least one of the stored information storage media.

[0016]

Therefore, a plurality of dealer terminal devices 2
In 3, for example, the purchase conditions for which data has been received are displayed on the display 112, and the dealer who has visually recognized the purchase conditions creates a corresponding sales quote. Alternatively, the dealer terminal device 23 automatically generates data of the sales quote in accordance with the purchase condition received by the data, and the seller confirms the sales quote on the display output of the display 112.

At this time, the dealer terminal device 23 of the dealer
The purchase conditions include not only general purchase conditions such as “1. Area”, “2. Time from station”, etc., but also the mutual relationship among a plurality of purchase conditions such as “7. Priority” and “8. As a result, the seller can easily create a sales quote that properly reflects the wishes of the general user.

Moreover, such "7. Priority"
Since the interrelationship between a plurality of purchase conditions "8. Subtraction conditions" is input in accordance with a specific format,
Using this as a search key or parameter, the trader terminal device 23 can automatically generate data of a sales quote.

Since the sales quotes thus created manually or automatically are transmitted from the dealer terminal devices 23 of a plurality of dealers to the mediation terminal device 22 by e-mail or the like (step S5), the mediation terminal device 22 Transfers the plurality of received sales quotes to the user terminal device 21 by e-mail or the like (step S6).

Since the user terminal device 21 receives the sales quotes of a plurality of dealers, the general user can compare the sales quotes of the plurality of sellers. If the general user can select one sales quote as desired, the contract request is transmitted to the mediation terminal device 22 (step S7). Since the data is transferred to the device 23 (step S8),
3 and a general user can establish a sales contract.

In the data processing method by the data processing system 20 of the present embodiment, the condition input screen 5
In 0, not only a plurality of kinds of purchase conditions but also at least a part of the mutual relations of the plurality of kinds of purchase conditions are input as data as purchase conditions. It can be well reflected in transactions.

However, the general user does not have to perform the complicated operation of inputting his / her own wishes in the form of text data, and the general user's wishes can be transferred to the mediation terminal device 22 or the trader terminal device 23 with good mechanical efficiency. Since data processing can also be performed, online transactions can be activated.

The present invention is not limited to the above-described embodiment, but allows various modifications without departing from the gist of the invention. For example, in the above embodiment, the sales quotation and the contract request are illustrated as data communication between the trader terminal device 23 and the user terminal device 21 via the mediation terminal device 22. However, this data communication is performed via the mediation terminal device 22. Instead, it is also possible to execute directly by the trader terminal device 23 and the user terminal device 21. Further, the communication method of sales quotes and contract requests is not limited to e-mail, and for example, general telephone and postal mail can be used.

Further, in the above embodiment, the CPU 101 operates according to the control program stored as software in the RAM 104 or the like, so that the mediation terminal device 2
It has been exemplified that various means are logically realized as the various functions 2. However, it is also possible to form each of these various means as unique hardware, and it is also possible to store a part of the various means as software in the RAM 104 or the like and form a part as hardware.

Further, in the above embodiment, the software installed in the HDD 105 in advance from the CD-ROM 108 or the like is copied to the RAM 104 when the mediation terminal device 22 is started, and the CPU 101 reads the software stored in the RAM 104 in this manner. Assuming that such software is stored in the HDD 105
It is also possible for the PU 101 to use it or to store it fixedly in the ROM 103 in advance.

Further, software is stored in the FD 106 or CD-ROM 108 which is an information storage medium which can be handled alone, and the FD 106 and the HDD 105
Although it is possible to install software in the AM 104, it is also possible for the CPU 101 to directly read the software from the FD 106 or the like and execute the processing operation without performing such installation.

That is, when the various means of the mediation terminal device 22 of the present invention are realized by software, the software only needs to be in a state where the CPU 101 can read and execute the corresponding operation. It is also possible to form a control program for realizing the various means as described above by a combination of a plurality of software. In this case, the information storage medium which is a single product has the mediation terminal device 2 of the present invention.
It is sufficient to store only the minimum necessary software for realizing Step 2.

For example, the CD-ROM 1 is stored in the mediation terminal device 22 on which an existing operating system is mounted.
In the case where application software is provided by an information storage medium such as 08, software that realizes various means of the mediation terminal device 22 of the present invention is realized by a combination of application software and an operating system, and thus depends on the operating system. The software of the part to be performed can be omitted from the application software of the information storage medium.
