  FIG. 1 is a system related diagram of the electronic commerce system of the present invention.

  The system 1 of the present invention is an electronic commerce system in which a user can make a transaction by accessing a seller server 10 from a communication terminal device 20 such as a personal computer via a communication network L such as the Internet. On the merchant server 10 side, information on products to be sold is registered in the product database 11.

The merchant server 10 is constructed as a Web server, and when the purchaser accesses the communication terminal 20 by accessing the merchandise server 10, the merchandise database 11 stores the merchandise desired by the purchaser from the merchandise database 11. The unit price is taken out, the screen information 12 of the product selection screen E2 including the grid-like list column 40 (shown in FIG. 5) arranged in two dimensions is edited, and the screen information 12 is used as the communication terminal of the purchaser. The product selection screen information 12 is downloaded and displayed on the display screen of the communication terminal 20 through a browser (not shown), and the product selection screen E2 (see FIG. 2) is selected. To be able to.

  The product database 11 is classified for each product, and includes product individual information 11a having at least two or more types of product classification information and product unit price, and product group common information 11b having common information about a plurality of related products. Consists of.

  In accordance with the operation of the purchaser's communication terminal 20, the seller server 10 displays common items based on the product group common information for a specific product group made up of a plurality of related products in the common column 30 (FIG. 5) of the product selection screen E2. Etc.), a grid-like list in which unit prices of a plurality of related products included in the product group are two-dimensionally arranged is displayed in the list column 40 (see FIG. 5 etc.) of the product selection screen E2. Display. Then, when a product is selected on the product selection screen E2, the planned number of purchases is input, and an ordering operation is performed, the order information is returned to the seller server 10.

  The functions, processing, product database data items and display screen of the system of the present invention are illustrated in FIGS.

  FIG. 2 is a diagram showing an example of the functional configuration of the system of the present invention. Subordinate to homepage A, as a function (screen) for the seller, product registration / modification screen B that enables individual product information and product group common information to be registered and modified, and system management / maintenance, etc. It has a management screen C and the like, and as a function (screen) for the purchaser, a user registration screen D, a product selection menu screen E1, a product selection screen E2 in which products can be ordered in a grid-like list, and a plurality of lists are bundled It has a polymerized product selection screen E3 (polymerization display) and the like.

  The screen for the seller is called by inputting a specific user ID and password for the seller (or for the manager) on the terminal connected to the seller server 10 or the Internet L. The purchaser's screen is called by the purchaser's operation on the purchaser's communication terminal 20 such as a personal computer connected to the Internet L.

  These Web screens are described in a page description language such as HTML or XML on the seller server 10 side, and are prepared as screen configuration information files, or are dynamically generated when requested by the purchaser. A browser installed in the computer 20 accesses the server 10 via the Internet L, downloads a necessary screen configuration information file, and displays it on the screen of the communication terminal 20 according to the file contents. The product selection screen information 12 described above is also generated as a screen configuration information file.

  Since the Web screen realizes a GUI (graphical user interface), if various functions of the system are configured by such a Web screen, not only information display but also data input from the personal computer 20 and the server 10 are performed. Transmission and page switching can be easily performed through the display screen.

  Further, based on the operation request from the purchaser side, the server 10 side drives CGI (Common Gateway Interface) or SSI (Server Side Include), retrieves the requested information from the product database 11, and based on the information. It is also possible to dynamically generate a screen configuration information file for a Web screen and display it on the purchaser communication terminal 20. That is, the seller server 10 generates a screen configuration information file to be displayed on the purchaser side by including variable data in the screen information of a fixed image prepared in advance, and sends it to the communication terminal 20 that requested it. .

  For example, after calling the product selection menu screen E1 on the purchaser communication terminal 20, if a product list of a specific product group is selected from the menu, the merchant server is based on the selection. Then, information on the target product group is extracted from the product database 11, and various product information is included as variable data in the product selection screen E2 including the common column 30 and the list table column 40 as will be described later. The selection screen information 12 is generated, and the screen information 12 is transmitted to the purchaser's communication terminal 20 to be displayed on the screen.

  FIG. 3 shows a main configuration of the system 1 of the present invention. In the figure, the display / accepting process 14 on the product selection screen E2, which is the main part of the system 1 of the present invention, the product database 11, the data input process 13 to the product database 11, and the operation when an order is received. The order processing 15 is illustrated, but the processing related to the user registration screen D and the management screen C, various screen configuration information files configured in HTML stored in advance, communication processing, and the purchaser communication terminal 20 operate. The browser is not shown. Hereinafter, each process will be described individually.

  The data input processing 13 executes an operation of storing and updating the product information registered and corrected in the product database 11 from the terminal 10A connected to the seller server 10 via the product registration / correction screen B. The data input to the product database 11 is not limited to registration and correction using such a Web screen, and product information data provided through the communication terminal 21 of the manufacturer or wholesaler is used as record information in the product database 11. Processing such as format conversion and editing may be used.

  The display / order reception processing 14 displays the product selection menu screen E1 on the purchaser communication terminal 20, and then causes the purchaser to select a product group on the product selection menu screen E1, and the product selection screen for the product group. When the common column 30 and the list column 40 are displayed in E2, and the purchaser is allowed to input the planned purchase number of the desired product in each cell of the list column 40, the total amount of the product whose quantity has been input is displayed. Thereafter, the purchaser is requested to apply for an order (steps 131 to 135). Note that the order reception process may be to finalize the order, or may be an expense estimation calculation operation in which product information is simply stored in the “shopping basket” prepared on the seller server 10 side.

  Such information transmission to the purchaser communication terminal 20 is performed via the product selection screen information 12.

  Based on the order information received by the display / order receiving process 14, the order receiving process 15 executes a process related to a predetermined order, such as a process for creating an order slip and checking inventory.

  The product database 11 includes at least a record including the items shown in FIG. 4A shows the item content of the individual product information record 11a, and FIG. 4B shows the item content of the product group common information record 11b. Here, clothing is exemplified as a product type handled in electronic commerce.

  The product individual information record 11a is generated for each product and includes information such as a product code, clothing classification, sex, color, size, and unit sales price. Here, the clothing classification is a classification of a large classification product group such as men's summer clothing (shirts) into small classification product groups such as polo shirts, T-shirts, and sleeveless shirts. Moreover, clothing classification, sex, color, and size are product classification information for classifying products, and can be extracted and classified by each classification information.

  In the commodity group common information record 11a, common items of commodity groups in which a plurality of individual commodities are grouped such as men's summer clothing (shirts) and ladies' accessories are registered. The record items include a product group code, a product group name, a material, a sales unit, a common product image, and the like.

  Note that the product database 11 is not limited to the above-described record classification and record configuration, and may be other types. It is sufficient that at least the product classification information, the sales unit price, and the like can be extracted for each product.

  5 to 7 are diagrams showing screen examples of the product selection screen E2.

  FIG. 5 shows a common column 30 for displaying common information of a small group of product groups (here, men's polo shirts), and a list column 40 arranged in a two-dimensional array with a horizontal axis for color and a vertical axis for size. The product selection screen E2 further includes a total command operation unit 51, an order command operation unit 53, and a total price display window unit 52.

  The total command operation unit 51 and the total price display window unit 52 may be displayed on a separate screen after selecting the selected product and the number of purchases without providing the product selection screen E2. For the product selection screen E2, the total command operation unit 51 and the total amount display window unit 52 incorporated can be operated while confirming the selected product while viewing the screen information. Convenient.

  In the common column 30, common items such as a product sample image 31, a product name, a material, and a sales unit extracted from the product group common information record 11b of the product database 11 are displayed. The product sample image 31 may be composed of not only photographs but also symbols and pictures.

  Further, in the list table column 40, the unit price 41a is displayed at the top of each cell 41, which is the intersection of the vertical and horizontal axes of the list, and the input operation window 41b for the planned purchase number is displayed at the bottom. In the input operation window 41b, the number of purchases may be directly input using a numeric keypad, or a multiple of sales units may be displayed in a pull-down menu so that the user can select from among them.

Note that the product information displayed as symbols, pictures, or photographs may also be displayed in the list column 40 . For example, if a colored polo shirt symbol is displayed in the color item column 43 or the entire row of each color is displayed in that color, the purchaser can input without making a mistake.

  Further, at the bottom of the screen, a total command operation unit 51 for requesting a total price calculation command based on the input quantity, and a total price display for displaying the total purchase price calculated based on the input planned purchase quantity The transmission button which comprises the window part 53 and the order instruction | command operation part 52 is arrange | positioned.

  After the purchaser calls this screen E2, when the planned purchase quantity is input to the input operation window 41b of the desired cell 41 in the list table column 40 and the total command operation unit 51 is operated, the selected product is identified. Information and the planned number of purchases are returned to the seller server 10, and the server 10 calculates the total purchase amount based on the planned purchase number and unit price of the product, and further adds up all the selected products. Product selection screen information 12 for displaying the total amount on the total amount display window 53 is transmitted to the communication terminal 20, and the screen is updated by the operation of the browser in the communication terminal 20 that has received the product selection screen information 12. . Each time such an operation is repeated, the display is updated. Thereafter, when the purchaser operates the send button 53, the ordering data for the product for which the planned purchase number has been input is transmitted to the seller server 10.

  In addition, when there are a plurality of product selection screens for different types of related products, the total amount of screens that have already been selected may be added up to calculate and display the total amount. Such a screen configuration will be described later with reference to FIG.

  As described above, the order data reception may be an operation in which the user ID is input in advance on the product selection menu screen E1 or the like, and the order is determined based on the user ID. It may be a tentative confirmation (put into shopping basket) operation until complete confirmation on a screen (not shown).

  In this example, the total amount is calculated on the seller server 10 side. However, when the product group is selected on the product selection menu screen E1 and the product selection screen information 12 is sent, the information is displayed. May be transmitted in which a calculation program for calculating the total amount is included as a script. That is, when the purchaser selects a product, inputs the planned number of purchases, and operates the total command operation unit 51, the merchandise selection screen information downloaded to the communication terminal 20 is not requested to the seller server 10 side. The total amount is calculated by a total amount calculation logic (program) included in 12. Moreover, when calculating in the communication terminal 20 side, the structure which abbreviate | omits the command by the total command operation part 51 may be sufficient.

  Further, when the communication terminal device 20 of the purchaser installs the sales support software distributed from the seller server 10 in advance and accesses the seller server and performs a request operation from the product selection screen E2, the above sales support is performed. The total amount may be calculated by driving the software. In addition, the sales support software may perform processing such as purchase history and product point accumulation so that information convenient for the purchaser can be stored on the communication terminal side.

  As described above, since the selection of products and the input of the planned number of purchases can be made in the checklist column 40 configured in a two-dimensional array, the purchaser can select a plurality of individual products on one screen and purchase. The number can be entered, so the order can be confirmed in a short time. Further, if the number of purchases is input, the total purchase amount is calculated and displayed, so that the order can be confirmed with only one screen.

  Further, since the common column 30 such as an image is displayed on the same product selection screen E2 as the list column 40 and is separated from the list column 40, common items such as the sample image 31, the material, the manufacturer, etc. This is very convenient because it is easy to see on the same screen as the product selection screen. The common items displayed in the common column 30 are divided not only on the screen but also in the records of the database 11 as product group common information different from the individual product information as described above, and an input screen corresponding to the record If you prepare, you can save time for data registration because it takes less time to input on the seller side.

  FIG. 6 shows another example of the product selection screen E2, which is a screen example in which all items of the product classification information can be displayed and selected on the same screen as the list table column 40. In this example, information common to related products is displayed in the common column, but the common column is not shown in the figure.

  On this screen, the purchaser can freely select items on the vertical axis and horizontal axis of the list column 40. When the purchaser selects “gender” for the gender and “red” for the color in the target product selection menu field 42, the product for the gentleman's red-designed men ’s summer clothing (shirts) is extracted and the horizontal axis is A clothing list and a list column 40 having a vertical axis as a size are displayed. Further, if the selection is changed at any time in the target product selection menu column 42, the list column 40 classified accordingly can be displayed.

  The selection method may be a method in which items on the vertical and horizontal axes of the list column 40 can be directly specified.

  Note that the input of the planned number of purchases to the cell 41, the calculation of the total purchase price, the display, and the order confirmation are the same as in the example of FIG.

  According to such a screen, even if there is a lot of product classification information, it is possible to narrow down the products and display a list, so it is easy to operate, and it does not take time to estimate costs and confirm orders .

  FIG. 7 shows an example of the product selection screen (overlay display) E3 shown in FIG. 2, and displays a list table column 40 in which the three types of product classification information of the product classification information are bundled and displayed. It is a thing. In this figure, the common column is not shown.

In the example shown in the figure, the clothing classification is set on the horizontal axis, the size is set on the vertical axis, and the color can be set by the tab 40b. On this screen E3, a plurality of lists 40a displayed in a grid pattern in a two-dimensional arrangement with the horizontal axis and the vertical axis are displayed in a superimposed manner. That is, the list table column 40 displays a plurality of tabbed two-dimensional list tables 40a overlapping each other.

When the purchaser operates the color designation tab 40b on the left shoulder from a plurality of two-dimensional list 40a with tabs, the entire two-dimensional list 40a of the target color classification is displayed, and the two-dimensional list 40a is displayed. A desired product can be selected from the cell 41. Further, when the tabs 40b of all the two-dimensional list 40a cannot be displayed, they can be moved and displayed by a scroll operation.

When the purchaser inputs a planned purchase number into the input operation window 41b of each cell 41 and operates the total command operation unit 51 while switching a plurality of two-dimensional list 40a with tabs , the total in the list 40a is displayed. The purchase price is displayed in the total price display window 52.

  Further, the total amount of products already selected and input in the other two-dimensional list 40a is added up and displayed in the total amount display window 54. Then, if the send button 53 is operated, orders are accepted for all the products for which the planned number of purchases is input.

  Note that the color designation tab 40b is color-changed and displayed for the list 40a once selected and entered so that the two-dimensional list 40a can be identified at a glance whether the number of purchases has been entered or not entered. Alternatively, the total purchase amount of the list 40a may be displayed in the display column 40c such as next to the color designation tab 40b.

  The calculation for displaying on the total amount display window unit 52 and the total amount display window unit 54 may be performed by either the seller server 10 or the communication terminal 11 of the purchaser. When the calculation program downloaded in the above is used, in order to calculate the total amount, the total purchase amount calculated in the other two-dimensional list 40a is displayed in the total display column 40c, and the information is used. The communication terminal 11 side can be operated.

  In this way, since all of the products classified by the three types of product classification information are displayed on a single screen and the quantity of the product can be input, the purchaser can select the desired product. Time to select and order can be shortened.
