Abstract

PURPOSE:To easily and rapidly retrieve data for required items by converting the numerical value of an inputted price data into a prescribed numerical value range band including the numerical value and using the numerical value range band as an index key. CONSTITUTION:A conversion table 1b makes a number indicating the approximate price of an automobile correspond to a numerical value range defined so that the upper digit next to the least significant digit of the number is a significant figure. When the approximate price of an automobile, e.g. 300,000 yen, required by a customer is inputted from a terminal equipment 9 and set up in a specified price storing part 5a, a conversion part 2b converts the approximate price into 250,000-350,000 yen by referring the table 1b, a stock control part 6a retrieves the data of the automobile belonging to the prescribed price range and transmits the retrieved result to the terminal equipment 9 through a line control part 4 and a display device displays the specifications and price of the automobile included within the prescribed price range. Consequently, the data of commodities included within the price range required by the customer can be easily and rapidly retrieved.

Description

[Detailed Description of the Invention] [Summary] When purchasing an item such as a used car, a customer usually
Specify an approximate price, such as around 00,000 yen. Therefore, by converting the index key from the number 300,000 to, for example, a range of 250,000 to 350,000, it is possible to automatically create an index key indicating the price range desired by the customer.

[Industrial application field]

The present invention relates to a method of searching item data from a product inventory file, and particularly to a method of searching item data using price as an index key.

For example, if we take used cars as a product, in recent years, as more and more used cars with multiple modifications have been distributed in the market, used car dealers and management centers are required to improve inventory, distribution management, and customer service. EDP processing is now being performed by connecting the two over a network. When a customer is looking for a used car, the most important condition is the purchase budget, so there is a need for a method that allows the customer to quickly search for a desired vehicle within an acceptable price range at a store.

[Conventional technology]

FIG. 3 is a block diagram of a conventional example. The following is an explanation using a used car as an example of a product. The same reference numerals indicate the same objects throughout the figures.

In the figure, a terminal device 9 is a device having a display device, a keyboard, a printer, etc., and is installed at a used car dealer's office, etc., and communicates with a center device via a communication line to allow customers to request information. It has the function of inquiring the inventory status of used cars.

The inventory file 3 is a file that stores and manages price versus vehicle data of used cars in stock, that is, vehicle type, color, equipment options, etc., arranged in order of price.

The line control section 4 has a function of controlling the line and controlling the exchange of data between the terminal device 9 and each part of the center apparatus according to the line protocol and interface.

The specified price storage unit 5a has a function of recording the price of the used car specified by the terminal device 9.

The inventory management unit 6a updates the vehicle data in the inventory file 3 when a vehicle enters or leaves the warehouse, and updates the vehicle data in the inventory file 3 when making an inventory inquiry.
It has the function of searching data on vehicles corresponding to the specified price from the terminal device and transferring it to the terminal device 9 via the line control section 4.

When purchasing a used car, a customer usually specifies a price of a car, for example, around 300,000 yen, and the customer's budget range at this time is usually around 200,000 yen.
The price is often between 50,000 yen and 350,000 yen.

Therefore, the conventional search method is to input the vehicle price twice on the terminal device, once for 6.2 million yen and once for 300,000 yen. How to obtain data on vehicles within the price range, or from the terminal device 9, 250,000 yen, 260,000 yen, 270,000 yen...
The method used was to search for data on vehicles costing more than 250,000 yen but less than 350,000 yen by inputting the price of 340,000 yen one by one.

[Problem that the invention seeks to solve]

As mentioned above, according to the conventional method, inputting desired price data from the terminal device 9 takes time and effort, and therefore,
There was a problem in that it took time to search and it was not possible to respond quickly to customer requests.

[Means for resolving issues]

FIG. 1 shows a block diagram of the principle of the present invention.

In the figure, reference numeral 2 denotes a conversion means that converts the numerical value of the input price data into a predetermined numerical range band that includes the numerical value, and uses the numerical value range band as an index key.

Therefore, the converting means 2 is configured to convert the specified price value into a predetermined value i3 range.

[Effect]

According to the present invention, by inputting a numerical value of the price of a product, the converting means 2 can automatically convert this numerical value into an index key of a predetermined price range including the numerical value indicating the specified price. You can easily and quickly search for data on the required items.

〔Example〕

Embodiments of the present invention will be described below with reference to FIG. The same reference numerals refer to the same objects throughout the design.

Components in FIG. 2 that correspond to those in FIG. 1 are surrounded by dashed lines.

In the figure, the conversion table 1b converts a number indicating the approximate vehicle price into an operating number (
For example, when a price value is expressed in units of 10,000 yen, the conversion table corresponds to a numerical range such that the significant figures are 100,000 yen digits.

The conversion unit 2b has a function of converting the contents of the specified price storage unit 6a indicating the estimated vehicle price specified by the customer into a number within a predetermined range by referring to the conversion table 1b.

Therefore, when the customer's desired estimated vehicle price (300,000 yen in the figure) is entered manually from the terminal device 9 and stored in the designated price storage section 5a, the conversion section 2b refers to the conversion table lb to calculate the estimated vehicle price ↑3. is converted into a number in a predetermined range (250,000 yen to 350,000 yen in the figure), the inventory management section 6a searches for data on vehicles belonging to this predetermined price range, and sends it to the terminal device 9 via the line control section 4. The display device is configured to display and output specifications and prices of vehicles in a predetermined price range.

〔Effect of the invention〕

As explained above, according to the present invention, data on product items within a customer's desired budget range can be easily and quickly retrieved.
