DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of trading electronic parts using an electronic network in a method of trading a certain product, and a server device for performing the trade, and more particularly to a supplier who sells electronic parts. The present invention relates to a method for trading electronic components using a computer network for buying and selling electronic components by grouping by buyer and / or buyer, and a server device for performing the trading.

2. Description of the Related Art Generally, when a circuit is constructed with electronic components such as a semiconductor, a semiconductor substrate, and a circuit element, a buyer obtains data such as the performance of the electronic components sold by each electronic component dealer. After that, I did the basic design of the circuit. Based on this circuit design, samples of electronic components are ordered and a mounted circuit is assembled. The operation of the circuit was confirmed, and the electromagnetic induction noise (EMI noise:
Electromagnetic interference noise) is measured, and the performance of the mounted circuit is evaluated. In reality, after such an operation check and performance evaluation, a large order of electronic components is actually placed.

In recent years, as the performance of electronic components such as semiconductor components has dramatically increased and the speed of circuit design has been required, electronic components including the performance of the electronic components and the stock status of the electronic components have been developed. It is required that the latest information on the product be available immediately. Conventionally, the planning, development, and manufacturing departments of each buyer obtain and organize the latest information on such electronic components, and distribute and distribute the materials to circuit designers for circuit design. Also,
If the information alone is not enough information, we may meet with the supplier's representative to receive a detailed explanation.

[0004] On the other hand, a supplier obtains information on a product requested by a buyer and the quantity of the product by consulting with a person in charge of the buyer. One buyer's request can be known by taking sufficient meeting time. However, it is often time-consuming and inefficient to know by meeting how many other buyers are requesting what kind of product and in what quantity. Therefore, it is usually the case that the majority of buyers are looking for what products they want, in order to understand the market conditions of the products and make the right part manufacturing decisions.
ing research).

[0005] In response to such a situation, in recent years, with the spread of the Internet, a service has been widespread in which manufacturers, which are suppliers of electronic components, open their own homepages and provide the latest information on electronic components to buyers. I have.

[0006]

In a service in which each supplier that manufactures electronic components establishes a homepage and provides the latest information on electronic components to buyers, the buyer obtains information such as the performance of each electronic component. However, it is not possible to grasp the status of the stock and the price of the product, and it is necessary to make an inquiry to a trading company or the like that sells electronic components as necessary. Also,
A search on the supplier's home page only gives information about the electronic components of the supplier that was searched. Therefore, there is an inconvenience in that information about an equivalent product of another company cannot be obtained, and information about electronic components must be similarly collected by searching the homepage of another supplier in the same manner. Further, even if the electronic component to be obtained is determined, the stock status and the product price fluctuate at the time of obtaining the electronic component, which may lead to a status different from the status at the time of design. In the worst case, there is a problem that requires redesign.

[0007] Further, the supplier often deals only with a specific buyer, and it is difficult to develop new customers required by the sales department of the supplier.

[0008] On the other hand, if a buyer suddenly needs an electronic component having a predetermined specification, it may not be possible to manufacture a supplier with a business during busy periods. In that case, it is possible to ask other suppliers, but in many cases there are concerns about uncertainty about the reliability of the product and whether it will surely meet the delivery date. Therefore, it is easy to hesitate to request a small or new supplier to manufacture electronic components.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned circumstances, and not only saves the buyer's transaction time, but also provides the most useful information from a large number of suppliers when purchasing a certain electronic component. An object of the present invention is to provide an electronic component trading method capable of specifying a plurality of suppliers and a server device therefor.

[0010] Another object of the present invention is to provide an electronic component trading method and a server device for the supplier, which enable a supplier to provide desired information to a specific buyer.

It is still another object of the present invention to provide an electronic parts trading method capable of finding a new business partner while ensuring reliability, and a server device therefor.

[0012]

According to the present invention, referring to an electronic mall connected to a terminal of a net user via a network, a plurality of trading companies in which the net user is another net user and electronic parts. In the electronic parts trading method of trading, based on instructions from the net user, grouping each trading company into groups, presenting each group to the terminal for each electronic component, based on each presented group, The present invention is provided by an electronic component trading method characterized by presenting an optimal combination of trading companies.

Further, according to the present invention, an electronic commerce in which a net user trades electronic components with a plurality of trading companies as other net users with reference to an electronic mall connected to a terminal of the net user via a network. A grouping means for grouping each trading company into groups based on an instruction from a net user, and presenting each group to a terminal for each electronic component;
And a company combination means for presenting an optimal combination of trading companies based on each of the presented groups.

An electronic component trading method using a network according to an embodiment of the present invention and a specific example of a server device therefor will be described with reference to FIGS. 1 to 12.

FIG. 1 shows that a buyer 1, a supplier 2, and a virtual mall server device 3 are connected to each other via a network 4 in an embodiment of a server device for trading electronic components according to the present invention. FIG.

The virtual mall server device 3 shown in FIG.
Are connected to a plurality of buyers 1 and a plurality of suppliers 2 via a network 4. The supplier 2 sells electronic components such as semiconductors, semiconductor substrates, and other electronic elements. The buyer 1 purchases an electronic component supplied by the supplier 2. As the network 4, for example, the Internet is used. However, the present invention is not limited to this as long as it is an information communication network. By the way, by connecting the virtual mall server device 3 in this way, in the virtual mall on the virtual mall server device 3, information on electronic components is exchanged between each buyer 1 and each supplier 2, and electronic components are exchanged. It becomes possible to sell. In general, in the virtual mall server device 3, the buyer 1 and the supplier 2 are connected via the network 4, so that the location where the buyer 1 and the supplier 2 are located does not matter when the product is bought and sold. . That is, if there is a device to which the network 4 can be connected, the network user can quickly buy and sell electronic components no matter where the buyer 1 or the supplier 2 lives in the world.

FIG. 2 is a functional block diagram showing an internal operation of the virtual mall server device 3 shown in FIG.

The virtual mall server device 3 is connected to the network 4 via the connection unit 11. Each database (hereinafter, abbreviated as DB) DB: data b
ase) is connected, and provides a lot of information to the buyer 1 and the supplier 2 through the network 4. That is, a supplier DB 13 in which information of electronic components to be provided for each supplier 2 and registration information are stored, and a buyer DB in which registration information is stored for each buyer 1
Fifteen. In addition, a sales history DB 14 storing a history of sales of electronic components by each supplier 2 and a purchase history DB 16 storing a history of purchases of electronic components by each buyer 1 are connected to a supplier DB 13 and a buyer DB 15, respectively. are doing. Further, there is a group information DB 17 having information in which each user is grouped for each desired buyer 1 or each desired supplier 2 for each supplier 2 or buyer 1.
In addition, an electronic component DB storing electronic component information
18 is connected to the connection portion 11. By the way, the group information DB 17 is not provided, and the information is stored in the supplier DB.
And may be set to be stored in the buyer DB. That is, information in which each user who is the supplier 2 groups desired buyers 1 is represented by the buyer D
B is set to be stored. Further, information in which each user who is the buyer 1 groups desired suppliers 2 is set so as to be stored in the supplier DB.

An information presenting unit 19 for presenting information such as registration information of the supplier 2 and the buyer 1, a search screen, and a group creation screen to the supplier 2 or the buyer 1 is connected to the connection unit 11. The information presentation unit 19 is also connected to the control unit 12 for controlling the operation in the virtual mall server device 3. This control unit 12
Is also connected to and controls the connection unit 11, the user registration unit 20, and the search unit 21. When the supplier 2 and the buyer 1 who use the virtual mall server device 3 register, the user registration unit 20 stores the information in predetermined storage areas of the supplier DB 13 and the buyer DB 15, respectively. Search unit 21
Is for the user who is the buyer 1 or the supplier 2 to search for information about the supplier 2 or the buyer 1 or information about the electronic components, respectively.

The supplier DB 13 stores electronic component information on electronic components such as semiconductors, electronic elements, and circuit boards. The electronic component information includes electronic component sales information and electronic component performance information. The electronic component sales information includes, for example, the product name of the electronic component, the name of the manufacturer thereof, the store (trading company, etc.), the number of stocks, the unit price, and the expected delivery date when purchasing is desired. The electronic component performance information includes, for example, the model name, manufacturer code,
The function and the performance of the electronic component corresponding to the function (for example, the operating clock frequency in the case of a microprocessor), the structure, the number of internal data bus bits, the number of address bus external terminals, the output format, the power supply voltage, and the specific application And so on.

From the supplier 2, electronic part sales information such as inventory of electronic parts and electronic part performance information on electronic parts manufactured by the supplier 2 are supplied to the supplier D.
The information is periodically sent to B13, and the electronic component sales information and the electronic component performance information in the supplier DB 13 are updated. Here, without waiting for the supplier 2 to provide the electronic component sales information and the electronic component performance information, the virtual mall server device 3 inquires the supplier 2 and actively sends the electronic component sales information and the electronic component performance information. The information in the supplier DB 13 may be collected and expanded. Such expansion of the information improves the reliability of the supplier DB 13. The order information of the electronic components is stored in the sales history DB 14. This information is used as a database for each buyer 1 as product purchase result information of the buyer 1 and as credit information of the buyer 1.

FIG. 3 is a diagram showing a series of states in which the buyer 1, the supplier 2, and the virtual mall server device 3 exchange information with each other via the network 4.

First, a virtual mall is opened on the virtual mall server device 3 (ST-A1). This virtual mall server device 3 is connected to a network 4, for example, the Internet, and can be connected from computer terminals all over the world. That is, buyers around the world 1
And the supplier 2 can connect to this virtual mall.

Next, the supplier 2 and the owner of the virtual mall server device 3 make a contract (ST-A2). At the time of this contract, the supplier 2 pays a contract fee to the owner of the virtual mall server device 3.

The buyer 1 and the owner of the virtual mall server device 3 make a contract (ST-A3). At the time of this contract, the buyer 1 pays a contract fee to the owner of the virtual mall server device 3.

In order to make a purchase contract for purchasing electronic components with a predetermined supplier 2 in the future, the buyer 1
Registration for contract is executed on the virtual mall server device 3.

The virtual mall server device 3 notifies the buyer 1 to the selected supplier 2 that there is a contract request. The virtual mall server device 3 notifies the supplier 2 whether or not to agree to the contract. With this, Supplier 2
Does not agree with the contract, or a contract is established between the specific buyer 1 and the specific supplier 2 (ST-A4).

The buyer 1 groups the suppliers 2 (ST-A5). Buyer 1 is the desired supplier 2
And group it by electronic component. Based on this grouping, buyer 1 purchases the desired electronic component from supplier 2 that sells it.

The buyer 2 searches the supplier 2 selling the desired electronic component from the virtual mall server device 3 (ST-A6). This search is usually performed from within the above group. However, it is preferable that the setting is made such that the supplier 2 outside the group can be searched. In this case, it is set so that a new group is created, a purchase contract is made with the supplier 2, and the new group can be registered in the group. Further, the supplier 2 may be registered in a desired group that has been existing without creating a new group.

The virtual mall server device 3 stores the supplier 2 matching the search condition of the buyer 1 into the supplier DB 13
(ST-A7).

The result searched in the virtual mall server device 3 is displayed on the terminal screen of the buyer 1 (ST-A8).

A quote request is transmitted from the buyer 1 to the supplier 2 via the virtual mall server device 3 (S
T-A9).

The supplier 2 transmits the estimation result to the buyer 1 via the virtual mall server device 3 in consideration of the purchase condition of the buyer 1 (ST-A10).

When the purchase result is determined by examining the estimation result from the supplier 2, the estimated electronic component is purchased (ST-A11).

FIG. 4A shows the buyer 1 shown in FIG.
Is a flowchart showing an operation of temporarily registering a supplier 2 in a database of a buyer 1. FIG.

This step is performed in the same manner as in step ST-
This corresponds to the case where the buyer 1 and the supplier 2 enter into a confidentiality agreement in A4.

When the buyer 1 logs in to the virtual mall server device 3 (log-in), a menu screen is presented to the terminal of the buyer 1 by the information presentation unit 19 (ST-B).
1).

When the supplier registration mode is selected from the menu screen, a supplier registration screen is displayed. A plurality of supplier names are listed and displayed on the supplier registration screen. For example, they are listed in order of preference. Search for the desired supplier name from the supplier name. In such a search, a search engine may be used. For example, the name of the supplier you want to search,
When the address and the electronic parts to be handled are input, information on the supplier 2 that matches the input data is presented on the screen. Then, when the registration button shown in the figure presented on the terminal of buyer 1 is clicked with a mouse or the like, buyer 1 is provisionally registered with the group of suppliers 2 who wants to make a transaction (ST-B2). ).

The temporary ID and the temporary password are provided to the supplier 2 by the control unit 12 in the virtual mall server device 3.
Issued by Then, the issued temporary ID and temporary password are transmitted to the supplier 2 by e-mail or the like via the Internet.

FIG. 4B is a flowchart showing an operation in which the supplier 2 shown in FIG. 1 performs confidentiality registration in response to a request from the buyer 1.

As described above, the buyer 1 and the supplier 2
Is temporarily registered, a screen appears on the screen of the temporarily registered supplier 2 prompting sign-up for a contract with the buyer 1. Then, the user logs in to the virtual mall server device 3 using the temporary ID and the temporary password transmitted by e-mail or the like (ST-C1). Alternatively, the supplier 2 may log in to the virtual mall server device 3 via the Internet using the temporary ID and the temporary password.

When the supplier 2 logs in with a predetermined temporary ID and temporary password, the information of the buyer 1 who has registered the supplier 2 is displayed (ST-
C2).

Then, the contract contents of the registration source are displayed on the screen (ST-C3). This contract includes, for example, a confidentiality contract such as not announcing that a transaction with the buyer 1 is not disclosed, a guarantee of a discount rate, a guarantee of purchased goods, and the like.

If the supplier 2 agrees to this confidentiality agreement or the like, sign up on a predetermined screen (ST-
C4). On the other hand, if the supplier 2 does not agree with the contract, an e-mail or the like is transmitted to the buyer 1 to that effect.

Then, when a field indicating agreement in the sign-up screen is clicked, a genuine ID character (id
An authentication character and its true password are automatically issued from the virtual mall server device 3 to the supplier 2 (ST-C5).

The supplier 2 can exchange electronic components with the buyer 1 via the virtual mall server device 3 using the authentic ID and the authentic password. As described above, since the information exchanged by the password is isolated from the external network 4, there is almost no possibility that the information is leaked to other buyers 1 and suppliers 2.

At the same time that the genuine ID and the genuine password are issued, the supplier 2 is newly registered as genuine in the information stored in the buyer DB 15 of the buyer 1, and the supplier 2 is displayed in the supplier list. (ST-C6).

FIG. 5 is a flowchart showing a process of creating a group of suppliers 2 by classifying the suppliers 2 which the buyer 1 shown in FIG. 1 desires to trade into the types set by the buyer 1. .

When a plurality of suppliers 2 are registered with a certain buyer 1, the suppliers 2 can be grouped into a specific group. By grouping the suppliers 2, a specific supplier 2 can be grouped by product. Therefore, when executing the transaction of goods by the network 4, it is possible to trade the goods from the group without individually selecting the supplier 2. This not only saves transaction time, but also allows a plurality of suppliers 2 to be identified as the most profitable from a large number of suppliers 2 when purchasing an electronic component. Further, the most valuable supplier 2 can be easily specified for each electronic component.

Referring to FIG. 5, a process of grouping suppliers 2 will be described.

The grouping of the suppliers 2 is performed by the following steps. First, buyer 1's terminal
It is connected to the connection unit 11 in the virtual mall server device 3 via the network 4. Login screen is information presentation part 1
9, when displayed on the terminal of the buyer 1, the genuine ID and the genuine password are entered in predetermined fields of the display screen, and the buyer 1 logs in to the virtual mall server device 3 (ST-D1).

The group creation mode is selected from the menu screen presented to the buyer's 1 terminal by the information presentation section 19 (ST-D2). Then, the control unit 12 displays a screen for group creation.

In order to create a group, there are a search mode in which the group is created based on the result of the search, and a manual mode in which the buyer 1 creates the group. Either of the modes is selected (ST-D
3).

When the search mode button is clicked, past transaction result information is referred to, and a search screen for group creation is displayed. The search screen is provided with items for inputting numbers and characters serving as keys for searching. The numbers and characters include, for example, the date of the transaction, the name of the electronic component, and the serial number. Based on these numbers and letters, purchase history D
A specific supplier 2 is searched from the logged-in buyer 1 transaction information in B16 (ST-D4).

Further, a sorting function for arranging search results in a predetermined order is added. The buyer 1 describes the target to be sorted in the “sort target” column. For example, there are part classification, supplier name, price, and part type name of the traded product. The component classification includes, for example, a CPU chip, a system LSI, or a general-purpose logic IC.

Then, the search result is displayed on the screen of buyer 1 (ST-D5).

FIG. 6 shows buyer 1 displaying search results.
2 shows a terminal screen of the first embodiment. The companies A, B, and C shown in FIG. 6 are supplier names that are listed and output on the screen based on the contents described in the sort target (in this example, the component classification of the traded product). Clicking "Details" displayed beside the supplier name displays detailed information on the supplier 2. For example, past transaction information and the like are displayed on the screen. The buyer 1 can refer to this detailed information to determine which supplier 2 is to be selected and put into the same group. By checking the check box, the suppliers 2 are grouped. For example, in FIG. 6, company A and company C are included in the same group. When the buyer 1 accepts the search result (the search result as shown in FIG. 6), he / she clicks the “Create Group” button shown in the lower right of FIG.

On the other hand, if the buyer 1 is not satisfied with the search result, the "re-search" button shown in the lower left of FIG. 6 is clicked (ST-D6). Then, the display screen returns to "Start search" of ST-D4, a search item is input, and the search is performed again. This step is repeated to create a desired group. A supplier 2 to be grouped into a predetermined same group is selected. In that case, some suppliers 2 may be selected from the above search results, and terms to be further sorted may be newly selected and searched again.

When the "Create group" button is selected and clicked, a screen for creating a group is displayed (ST).
-D7). The buyer 1 selects the supplier 2 based on this, and a group is created.

FIG. 7 shows a display screen of the terminal on which the group creation screen is displayed. As shown in FIG. 7, a column for the created group name is provided. This column describes the group name that buyer 1 considers appropriate. Also,
The group name may be automatically entered by referring to the sort target column and the supplier name output in ST-D5.
In this case, for example, some of the characters described in the sort target column and characters common to a plurality of supplier names output in ST-D5 are combined to form a group name.
In addition, a comment section is provided. In this column, ST
-The numbers or characters for the search entered in D4 are automatically entered as they are. Of course, buyer 1
Can be changed to a more appropriate word. In addition, a column of the supplier list and a selection column (selected supplier list) are provided. The selection field is filled with the name of the supplier belonging to this group. The supplier 2 entered in this selection column is selected from the column of the supplier list shown in the lower left of FIG. What is displayed in the column of the supplier list is set so that all the suppliers 2 are displayed. However, the only supplier 2 that can be selected from this column and moved to the selection column is the supplier 2 that has made a contract with the buyer 1. Supplier 2 which can be moved to this selection field, as explained above,
Only the supplier 2 who has made a confidentiality agreement with the buyer 1 who has created the group in which the list is displayed. In this field, the only supplier 2 to be selected is the one for which the above-mentioned sign-up has already been executed. Therefore, only the highly reliable suppliers 2 that have made the contract are grouped.

On the other hand, in the above-described group creation, buyers 1 are grouped by supplier 2 and buyers 1 are grouped.
Groups may be created. The grouping is similar to the above-described method in which the suppliers 2 are grouped. In this case, in FIG. 7, the supplier list and the selected supplier list become a buyer list and a selected buyer list, respectively. As a result, the supplier 2 can exclude buyers 1 who do not want to trade, and can transmit advertisements and the like for specific electronic components to specific buyers 1.

FIG. 8 is a diagram showing a terminal screen of the buyer 1 on which an example of a group created by the group creation step of FIG. 5 is displayed. Specifically, for example, transaction products are classified and grouped. That is, they are grouped for each same product. Further, a predetermined character string, for example, a memory is searched, and the suppliers 2 relating to the memory are classified as the same group. Then, a group name corresponding to the transaction product is given to each group, and the transaction supplier is classified from the transaction result information.

For each group, a group name indicating the attribute of the classified supplier 2 is displayed. In the example shown in FIG. 8, it is an ABC factory series. In addition, information on electronic components to be traded with the supplier 2 in the group is displayed as a comment. In FIG. 8, the memory, 128 Mbytes
e, commented on operating frequency of 130 MHz. Further, the names of the suppliers in the group are listed and displayed (in FIG. 8, ABC sales, ABC trading companies, LMN sales, X
YZ trading company etc.). Finally, the names of buyers dealing with those suppliers 2 are displayed (in FIG. 8, XXX
Company).

On the other hand, when the supplier 2 groups the buyers 1, the column of the supplier 2 in FIG. 8 becomes the column of the buyer 1, and a list of buyers 1 of this group created by the supplier 2 is shown. The column of buyer 1 is the column of supplier 2, and the name of the supplier who created this group is displayed.

In the above-described group creation step, a group is created using the search mode, but the group can be created manually as an option. That is, when the search mode is not selected in ST-D3 of FIG. 5 and the process immediately proceeds to the group creation of ST-D7, the buyer 1 directly writes in each column of the screen shown in FIG. At this time, the result of the search for the predetermined character string from the past transaction result information is displayed, and the detailed transaction result information of each displayed supplier 2 is displayed, and the buyer 1 analyzes it, Preferably, the entry by the buyer 1 is performed. Also, groups can be created offline. That is, in a state where the terminal of the buyer 1 is not connected to the net, FIG.
The buyer 1 makes a direct entry into each field of the screen shown in FIG. Since the buyer 1 can perform an input operation under such an offline state, the network connection fee is not charged during the input operation. Therefore, the buyer 1 can save the connection fee, and the buyer 1 can perform the input operation with sufficient time.

FIG. 9 shows an operation in which a buyer 1 appropriately selects a high-quality supplier 2 that sells an electronic component to be purchased, and requests the supplier 2 to estimate an electronic component to be purchased. It is a flowchart.

The buyer 1 logs in to the virtual mall server device 3 and a mode selection menu screen is displayed (ST-E1).

A purchase mode is selected from the menu screen (ST-E2).

As shown in FIG. 10, a screen for entering details of the product desired to be purchased is displayed. Buyer 1 enters the classification, title, and summary in the description fields at the top of the screen.
In the classification, whether the electronic component to be purchased is a sample, a mass-produced product, a compatible product, or the like is entered. In the title, a title that accurately indicates the electronic component to be purchased is entered. For example, "urgent purchase of analog products", "materials for new products", and the like. In the summary, information on other electronic components to be purchased is entered. For example, "Analog product for XX product development. Necessary time is very short." The characters written in these items are referred to and used for a search in a later step.

Usually, when purchasing electronic parts,
In many cases, a plurality of electronic components are purchased at the same time. For example, the electronic components required to make one board are:
About 300 parts. Therefore, in the detailed entry screen of the product desired to be purchased in this embodiment, columns are set so that estimates for a plurality of electronic components can be calculated. A column for describing a part for which an estimate is desired has a plurality of items. That is, there are a part classification, a manufacturer name, a part type name, a desired unit price, a quantity, a necessary time, a purchase condition and the like. The component classification describes a generic name of electronic components. For example, a CPU, a memory, and the like. The maker name is the name of an electronic device manufacturer that produces the electronic component. The component type name is a name corresponding to the performance of the electronic component on a one-to-one basis, and usually includes a series of character strings including alphabets and / or numbers. The required time is a time when the buyer 1 needs the electronic component, and is a delivery time of the electronic component. The purchase condition is a settlement condition or the like. Some of these items must be filled out. For example, the part classification, the number, and the required time are required items (ST-E3).

Next, the group of the supplier 2 is designated. For this specification, there is a method in which a predetermined group is selected by the buyer 1 in the group specification column, or a group is automatically selected to some extent (ST-E).
4).

In this group designation field, a group can be selected from the groups in which the supplier 2 who has already created the buyer 1 is registered. As a result, the buyer 1 can select the supplier 2 from the group that wants to purchase (ST-E5).

When the item “automatic” in the group designation column is selected, the group that matches the product that the buyer 1 wants to purchase is automatically selected by the virtual mall server device 3.
Select. This selection is performed based on this information, the contents of the desired purchase part, and the past transaction history with reference to the information described in the comment when the group is created (ST-E6).

Several groups are selected from the automatically selected groups. Buyer 1 narrows down to one group from these selected groups (S
T-E7). When narrowing down, the buyer 1 selects a supplier 2 to purchase parts with reference to a screen on which detailed information of the supplier 2 in each group is described. Specifically, as shown in FIG. 11, a list of the suppliers 2 in the group is displayed, and the detailed information can be referred to by clicking on the details column next to the name of the supplier 2. . The detailed information includes transaction result information that describes the status of transactions in the past, and recommendation information that describes compatibility with electronic components of the company's or other companies' products, particularly information on compatible components. The supplier 2 list of this detailed information can be sorted by price, delivery time, etc., with reference to the past transaction history.

Next, whether or not a group is created is selected (ST-E8).

When a new group is created on this narrowing-down screen, a group is created in the same manner as in the group creation step described above (ST-E9).

When “No group created” is selected on the narrowing-down screen of the supplier 2, the transaction content confirmation screen is displayed.
The information is displayed on the terminal of the buyer 1, and the supplier 2 who is to request an estimate and the detailed information of the electronic component to be purchased from each supplier 2 are displayed (ST-E10).

More specifically, a supplier name is displayed as shown in FIG. 12, and detailed information of the electronic component is displayed beside the name. The buyer 1 makes a final confirmation of the quote request on this transaction content confirmation screen.

If the user accepts the above contents, the user clicks an OK button or the like. With this click, the quote request to the selected supplier 2 is completed (ST-E1).
1). On the other hand, when canceling the estimate, a predetermined estimate cancel button is clicked.

In the system described above, registration and I
D and only the buyer 1 or the supplier 2 having the password can utilize the database in the virtual mall server.
