Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a price data management device capable of simultaneously managing old product specification price data and new product specification price data.

[0002]

2. Description of the Related Art Conventionally, for example, an automobile, which is a commodity, is sold by adding a plurality of options, which are various types of accessory components, to a vehicle body which is a basic component.
That is, at automobile dealerships, a plurality of types of products with the same body but different attached options are lined up and sold. Customers can freely select their favorite tire, outer plate, and option from the prepared lineup. The body lineup of these vehicle bodies and options are usually changed in a cycle of several years. In addition to selling the new lineup, the dealers also continue to sell the options of the old type for customers who have purchased the old type body. The store needs a price data management device that holds all prices of options to be sold as a database and can quickly output the price corresponding to the selected option.

When the lineup is changed, it is necessary to rewrite the old price database with the new price database. Here, if the old price data is completely rewritten to the new price data, the database cannot be used when a customer who wants the old option comes, so the old price data must be left as a database.
Conventionally, a database for managing at least the old and new generations 2 has a storage area for separately storing an old price database and a new price database, and the price data is updated when the lineup is changed when the price data for the new lineup is created. , The price data of the old lineup is deleted, the current price data which is the previous generation of the deleted lineup is migrated to the empty area, and the new lineup of the new lineup is stored in the area where the current price data is stored. I remembered the price data.

[0004]

However, the conventional price data management device has the following problems. That is, the price data management device, as an internal storage means,
Since it is necessary to have two areas, an area for storing new price data and an area for storing old price data, there is a problem that the storage means such as a hard disk, which is an internal storage means, becomes large and the apparatus becomes large in size, and the cost increases. there were. further,
When sending new price data via communication line,
Since another storage area for storing the received new price data is required for the time being, it is necessary to secure three areas for storing the price data group, and there is a problem that the storage means becomes larger and the cost increases. .

An object of the present invention is to solve the above-mentioned problems and to provide a price data management device capable of storing two price data, old and new, in a small internal storage area.

[0006]

In order to solve the above problems, the price data management device of the present invention has the following configuration. (1) A price data management device that manages old product price data indicating each specification of an old product group and its price, and new product price data indicating each specification of a new product group and its price, By comparing the product price data and the new product price data, the specification difference item expressing the specification difference of the old product price data with respect to the new product price data and the price item expressing the price data based on the specification difference are compared. It has a creation unit to create.

That is, using the new product price data as reference data, only the portion of the old product price data different from the new product price data is extracted and stored as the specification difference item and the price difference based on the difference item. Here, the price difference is also expressed as a difference with respect to the new product price.

(2) Further, in the device described in (1), if the specification difference is new, or if the specification difference is eliminated this time, the specification difference does not change but only the price data changes. It is characterized in that the case is expressed by different specification difference items. If the specification difference is new, that is, if the specification is in the new product price data but not in the old product price data, it is determined to be a new specification and the specification difference item is expressed as "new". Also, if the specification difference has disappeared this time, that is, if the specification is in the old product price data but not in the new product price data, it is determined that it is an abolished specification and “discontinued”.
To express. Further, when the price does not change and the specification does not change, the specification difference item is expressed as “unusual”.

According to the price data management devices of (1) and (2), only the specifications and prices different from the new product price data in the old product price data are stored, so that the entire data amount can be reduced. The capacity of the hard disk can be reduced.

(3) Further, in the device described in (1) or (2), when the information amount of the commodity price data has a unit, the connection between the units is secured by a serial number. Characterize. The serial number indicates a connection between units and is a numerical value used to keep the connection between units below a certain number.

BEST MODE FOR CARRYING OUT THE INVENTION A price data management device according to an embodiment of the present invention will be described in detail with reference to the drawings. FIG. 1 is a conceptual diagram showing the configuration of the price data management device. Data collating means 1 for comparing and collating old and new data
In 3, the new product price data storage means 11 for storing the individual specifications of the new product group and the new product price data showing the price thereof, and the individual product specifications of the old product group and the old product price data showing the price thereof are stored. The old product price data storage means 12 is connected. Further, the data collating means 13 is connected to a data output means 14 for providing data to the user. FIG. 2 shows a specific device that constitutes the price data management device. The personal computer 27 is a CP which is a data processing means.
U24, hard disk 26 as internal storage means, I /
It is composed of a basic input / output driver 23 which is an O interface, and a communication input / output driver 25 having a function capable of communicating with an external device through a telephone line or the like. Further, the personal computer 27 has a console 21, which is an external input / output means,
Auxiliary external storage device 22 such as a floppy disk drive
Are connected.

The hard disk 26 stores a control program for the price data management device. The contents of the control program are shown in the flow charts of FIGS. 3 to 8, and the control program will be described. Until the comparison of all items is completed (S1), the process proceeds to S2. The data matching unit 13 reads a part of the old product price data from the new product price data storage unit 11 (S2). Next, the data matching unit 13 reads the new product price data corresponding to the previously read old product price data from the old product price data storage unit 12 (S3). Then, the old product price data and the new product price data are compared (S4).

Then, if the specification code and its set are not changed and only the price is changed (S5, YES), a change code "change" is added (S51). Next, the new price this time is registered (S52). Next, the line is changed and a new code "new" is added (S53). Next, the value obtained by subtracting the new product price from the old product price is stored in the price column (S54). Next, it is checked whether the specification code is an option (S5).
5). If it is an option (S55, YES), then it is checked whether the serial number of the option is within 4 (S55).
551). If the option serial number is within 4 (S55
1, YES), and proceed to E shown in FIG. Then, the old and new categories are added as exceptional conditions (S551a). And S1
It returns to (S551b).

When the option is 5 or more (S551, N
O), if there is a standard option that is old but not new (S552, YES), the process proceeds to D in FIG. Then, the target specification code and the old and new classification are added as exceptional conditions (S552a). Then, the process returns to S1 (S552
b). If there are 5 or more options and there is no old and new option (S552, NO), the target specification code and old / new classification are added as exception conditions to the standard options of both old and new (S553). . And
It returns to S1 (S554).

If the specification code is not an option (S55, NO), it is checked whether the serial numbers of the old and new categories are within 4 (S56). If the serial numbers of the old and new categories are within 4 (S56, YES), the procedure advances to B shown in FIG. Then, the target code and the old and new categories are added as exception conditions (S
561). Then, the process returns to S1 (S562). If the old and new categories are 5 or more (S56, NO), if there is a standard option that is old and not new (S5).
7, YES), and proceed to C in FIG. Then, the target specification code is added as an exceptional condition (S571). And S
It returns to 1 (S572). If there are 5 or more options and there is no old option and no new option (S5
(7, NO), old and new are standard options with exception code and target specification code and old and new classification (S5)
8). Then, the process returns to S1 (S59).

Next, when the specification code and the set are changed, or when the specification and the set are not changed and the price is not changed (S5, NO), the process proceeds to A in FIG. If the specification code is not present this time but is present this time (S6, YES), the new code is added (S61), and the new price of this time is registered (S62).
Then, the process returns to S1 (S63). Next, if the specification code is present last time and is not present this time (S7, YES), the abolition code "abandoned" is added (S71). Then, the process returns to S1 (s7
2). Next, if there is an exception condition last time and the exception condition is not present this time (S8, YES), the change code “unusual” is added (S81), and the price is set to 0 yen (S82). next,
The line is changed and a new code "new" is added (S83), and a value obtained by subtracting the new price from the old price is registered (S84). Next, the old and new classification and the target specification code are attached (S85). Then, the process returns to S1 (S86).

In S1, the program ends when all items of the new product price data and the old product price data have been compared (S10).

The operation of the flowchart described above will be described based on a specific case. FIG. 10 illustrates a part of the old product price data. Further, FIG. 11 shows a part of new product price data corresponding to the old product price data. The data of FIG. 10 shows each specification of the vehicle model SV45-A and its price. The vehicle type is a symbol that represents the type of vehicle body. On the horizontal axis, tires, outer plates, and options that can be mounted on the vehicle body are listed. Here, the tire, the outer plate, and the lining are necessary for the vehicle, which is different from the options that are not always necessary.

In FIG. 10, "●" of the tire BBB is shown.
Indicates that the tire BBB is installed as standard equipment. In the case of standard equipment, since the price is included in the vehicle body price from the beginning, the vehicle body price does not change. In addition, the numbers in the bottom column of the tire CCC are 10,000 yen higher at the dealership, which is a car dealer, than the standard vehicle price when the tire CCC is installed and the price is equipped with standard equipment. It represents that the wholesale price to the store will increase by 1000 yen. Next, option 10A, option 20A, and option 2
1A is standard equipment, and its price has been included in the vehicle body price from the beginning.

On the other hand, when the option 30A is installed,
It represents that the price will increase by 20,000 yen at the dealer car dealer, and the wholesale price from the manufacturer to the dealer will increase by 2000 yen compared to the standard vehicle price. Next, an exception represents a case where the price is reduced by combining with other options. That is,
Exception 30A, if the option 30A is installed in combination with the option CCC, the price will increase by 5000 yen at the dealer car dealer and the wholesale price from the manufacturer to the dealer will increase by 500 yen compared to the standard vehicle price. Expresses that. This is option 30A
It is expressed that it is 75% less than when it is installed without combining with the option CCC.

Next, the new / old category is an item indicating whether it is a new product or an old product. In the present embodiment, the new product is indicated by the specification code 80C and the old product is indicated by the specification code 80A. Next, the outer plate represents the type of the outer plate of the vehicle such as the paint color. The outer plate DDD is mounted as standard, and the vehicle price does not change. Further, the lining represents the type of material, color, etc. of the interior of the vehicle. The liner FF 12 is not attached as standard, but since the price change is 0 yen, it indicates that the price does not change.

Next, FIG. 11 will be described. FIG. 11 shows a part of new product price data corresponding to the old product price data shown in FIG. The data in FIG. 11 corresponds to that in FIG.
Similar to 0, the new specifications and new prices of the vehicle model SV45-A are shown. In FIG. 11, the tire CCC
"●" indicates that the tire CCC is installed as standard equipment. The numbers in the lower column of the tire BBB are
When the tire BBB is installed, the price is increased by 10,000 yen at a dealer, which is a car dealer, and the wholesale price from the manufacturer to the dealer is increased by 1000 yen with respect to the standard vehicle price. Next, the option 10A and the option 15A are standard equipment, and the price is included in the vehicle body price from the beginning. Option 3
When the 0A is installed, it represents that the price increases by 25,000 yen at the dealer car dealer, and the wholesale price from the manufacturer to the dealer increases by 5000 yen compared to the standard vehicle price.

Next, the outer plate represents the type of outer plate of the vehicle such as the paint color. When using the outer plate DDD, the price will increase by 10,000 yen at the dealer car dealer, compared to the standard vehicle price, and the wholesale price from the manufacturer to the dealer will be 1
It expresses that it will increase by 000 yen. Also, the lining F
When F12 is adopted, the price is increased by 10,000 yen at a dealer, which is an automobile dealer, and the wholesale price from the manufacturer to the dealer is increased by 1000 yen with respect to the standard vehicle price.

Next, by the function of the price data management device,
The table shown in FIG. 9 is completed. The method of creating this table will be described. This price data management device mainly stores the new product price data shown in FIG. 11, and stores the old product price data shown in FIG. 10 as a difference from the new product price data. First, a method of storing the tire BBB shown in FIG. 11 will be described. First, the old product price data regarding the tire BBB is read (S2), and the new product price data is read (S3). Then, the old and new data are compared (S4).
Here, "ta" representing a tire is stored as a master classification, and "BBB" is stored as a specification code. Next, since the specification code and the set of the tire BBB are not changed, only the price is changed (S5, YES), a change number is assigned (S51). Specifically, “unusual” is stored in the correction category. Then, the new price data is registered (S52). Specifically, in the price column, 10000 yen, 1
Remember 000 yen. Thereby, the new price of the tire BBB is stored.

However, when the owner of the old vehicle purchases the tire BBB, since the tire BBB is usually sold at the old price, the old price of the tire BBB shown in FIG. 10 must be stored. Next, a method of storing the old price will be described. It is possible to represent the old price on the same line as the new price, but doing so makes the table large and inconvenient for handling and searching. Therefore, in the price data management device of the present embodiment, the number of characters per line is limited to 80 characters, so a special storage method is required. Number 2
In step S53, a "new" code is added to the correction category.
Next, the value obtained by subtracting the new product price from the old product price is stored (S54). The old price is "●" and it is 0 yen, and the new price is 1.
10,000 yen and 1,000 yen, so -10000, -100
0 is stored in the price column.

Next, since the specification code BBB is a tire and is not an option (S55, NO), the serial numbers of the old and new categories are confirmed (S56). Here, the serial number is a code for indicating the relation between different rows. Serial number is 2
Therefore (S56, YES), the process proceeds to B shown in FIG. Then, the target specification code and the old and new classification are added as an exceptional condition (S561). That is, in the number 2 in FIG. 9, BBB is stored as an exceptional condition and the specification code indicates the old classification 8
Memorize 0A. Then, the process returns to S1 (S562).

Next, data storage regarding the tire CCC will be described. First, the old product price data is read (S2), and the new product price data is read (S2).
3). Then, the old and new data are compared (S4). Here, "ta" representing a tire is stored as a master classification, and "CCC" is stored as a specification code. Next, since the specification code and the set of the tire CCC are not changed and only the price is changed (S5, YES), a change number is assigned (S51). Specifically, “unusual” is stored in the correction category. Then, the new price data is registered (S52). Until the new price, the tire CCC is a standard product, so register 0 yen as the price. Thereby, the tire C
The new CC price is stored.

However, when the owner of the old vehicle purchases the tire CCC, since the tire CCC is usually sold at the old price, it is necessary to store the old price of the tire CCC shown in FIG. In No. 4, a "new" code is attached to the correction category (S53). Next, the value obtained by subtracting the new product price from the old product price is stored (S54). Old price is 10,000 yen, 1
1000 yen because the new price is 0 yen and 1000 yen
0 and 1000 are stored in the price column.

Next, since the specification code CCC is a tire and is not an option (S55, NO), the serial numbers of the old and new categories are confirmed (S56). Since the serial number is 3, (S5
6, YES), and proceed to B shown in FIG. Then, the target specification code and the old and new classification are added as exceptional conditions (S56).
1). That is, in the number 4 in FIG. 9, the exceptional condition is C
CC is stored, and 80 A indicating the old classification is stored in the specification code. Then, the process returns to S1 (S562).

Next, the data storage regarding the option 10A will be described. Since the specification code, set, and price have not changed (S5, NO), the process proceeds to A shown in FIG.
Then, since the specification code is present both before and this time (S6, NO and S7, NO), and since there is no exceptional condition both last time and this time (S8, NO), all items have not been compared (S9, NO), and returns to S1 (S10).

Next, the data storage regarding the option 15A will be described. Since the specification code, set, and price have not changed (S5, NO), the process proceeds to A shown in FIG.
And since there is no specification code last time, it is this time (S6
YES), as shown by the number 5 in FIG. 9, the new code "new"
Is stored (S61). Next, the current price is registered (S62). Option 15A is a standard product, so
Register 0 yen as the price. Then, the process returns to S1 (S6
3). Next, the specification code 80C indicating the old and new classification will be described. Since there is no specification code this time, there is this time (S
6, YES), the new code "new" is stored as indicated by the number 6 in FIG. 9 (S61). Next, the current price is registered (S62). Since the option 15A is a standard product, 0 yen is registered as the price. Then, the process returns to S1 (S63).

Next, data storage relating to the outer plate DDD will be described. “Outer” representing the outer plate is stored as the master classification, and “DDD” is stored as the specification code. Next, since the specification code and the set of the outer plate DDD are the same and only the price is changed (S5, YES), a change number is assigned (S51). Specifically, “unusual” is stored in the correction category. Then, the new price data is registered (S52). Specifically, 10,000 yen and 1,000 yen are stored. As a result, the new price of the outer plate DDD is stored.

However, when the owner of the old vehicle desires to mount the outer plate DDD, the outer plate DDD is usually sold at the old price, and therefore the old price of the outer plate DDD shown in FIG. 10 must be stored. There is. In No. 8, a "new" code is attached to the correction category (S53). Next, the value obtained by subtracting the new product price from the old product price is stored (S54). Old price is "●" and 0
Since it is a yen and the new prices are 10,000 yen and 1000 yen,
10000 and -1000 are stored in the price column. next,
Since the specification code DDD is the outer plate and is not an option (S55, NO), check the serial numbers of the old and new classifications (S
56). Since the serial number is 4 (S56, YES), the process proceeds to B shown in FIG. Then, the target specification code and the old and new classification are added as an exceptional condition (S561). That is, in the number 8 in FIG. 9, DDD is stored in the exceptional condition and 80A indicating the old classification is stored in the specification code. Then, the process returns to S1 (S562).

Next, data storage regarding the lining FF 12 will be described. “Inside” representing the outer plate is stored as the master classification, and “FF12” is stored as the specification code. Next, since the specification code and the set of the liner FF 12 do not change, only the price changes (S5, YE
S), and a change number is attached (S51). Specifically, “unusual” is stored in the correction category. Then, the new price data is registered (S52). Specifically, 10,000 yen and 1,000 yen are stored. As a result, the new price of the liner FF 12 is stored.

However, when the owner of the old vehicle desires to install the lining FF 12, the lining FF 12 is usually sold at the old price. Therefore, the old price of the lining FF 12 shown in FIG. 10 must be stored. There is. At No. 10, a "new" code is added to the correction category (S53). Next, the value obtained by subtracting the new product price from the old product price is stored (S54). The old price is 0 yen and the new price is 10,000 yen and 1000 yen,
-10000 and -1000 are stored in the price column.

Next, since the specification code FF12 is a lining and not an option (S55, NO), the serial numbers of the old and new divisions are confirmed (S56). Since the serial number is 5, (S5
(6, NO), it is checked whether or not there is a standard option that is an old option but not a new option (S57). In the present embodiment, the option 21A is applicable (S
57, YES), and proceed to C shown in FIG. Then, the target specification code is attached as an exceptional condition (S571). Specifically, the option 21A is stored as the specification code, and the old category 80A and the lined specification code FF12 are stored as the exceptional conditions. Here, the serial number is 2.

Next, data storage regarding the option 30A will be described. As for 30A in FIG. 10, only the price has changed without changing the specification code and the set (S5, YES), so a change number is assigned (S51). Specifically, in the number 11 in FIG. 9, the modification category is “unusual”.
Memorize Then, the new price data is registered (S5
2). Specifically, 25,000 yen and 5000 yen are stored in the price column. As a result, the new price of the option 30A is stored.

Next, in the number 13, the "new" code is added to the correction classification (S53). Next, the value obtained by subtracting the new product price from the old product price is stored (S54). Old price is 20000 yen, 2000 yen, new price is 25,000
Since it is yen and 5000 yen, -5000 and -3000 are stored in the price column. Next, since the specification code 30A is optional (S55, YES), the serial numbers of the old and new divisions are confirmed (S61). Since the serial number is 3 (S56, YES),
Proceed to E shown in FIG. Then, the old and new categories are added as exceptional conditions (S551a). That is, in the number 13 of FIG. 9, 80A is stored as the exceptional condition. Then, the process returns to S1 (S551b).

Next, since the exceptional condition of the option 30A disappears this time since it existed the last time (S8, YES), the change code is added to the number 12 in FIG. 9 (S82) and the price is set to 0 yen ( S83). Next, at number 14 in FIG. 9, a new code "new" is added (S83), and the value obtained by subtracting the new price from the old price is stored (S84). Specifically, since there is no data in the new price data, 5000 yen and 500 yen are stored by subtracting 0 yen from the 5000 yen and 500 yen shown in the exceptional data of 30A of FIG. Then, the old division 80A and the target specification code as an exception condition are stored in the old and new divisions (S85). Then, the process returns to S1 (S86).

Next, data storage regarding the option 20A will be described. The option code, set, and price of option 20A have not changed (S5, N
O), and proceed to A shown in FIG. And since there is no specification code this time since this time (S6, NO) (S7, YES),
As indicated by the number 15 in FIG. 9, the abolition code “abandoned” is stored (S71). Then, the process returns to S1 (S72).

With the above operation, all specifications and prices of both data can be extracted from the old product price data of FIG. 10 and the new product price data of FIG. 11 into the table of FIG.
By storing the table represented in the form of FIG. 9, both old and new product price data can be stored with a small storage capacity.

As described in detail above, according to the price data management device of the present embodiment, the old product price data stored in the old product price data storage means 12 and the new product price data storage means 11 are stored. A data collation that compares the new product price data and creates a specification difference item that represents a difference in specifications of the old product price data with respect to the new product price data, and a price item that represents price data based on the specification difference. Since the means 13 is provided, only the specifications and prices different from the new product price data in the old product price data are stored, so that the entire data amount can be reduced,
The capacity of the hard disk etc. can be reduced and the price data management device can be made compact. Also, cost reduction can be realized.

Further, the price data management apparatus of the present embodiment is a new specification when the specification difference is new, that is, when the specification exists in the new product price data but not in the old product price data. Therefore, the specification difference item is expressed as “new”, and if the specification difference has disappeared this time, that is, if the specification is in the old product price data but not in the new product price data, it is abolished. It is judged that it is a specification that has been changed, and is expressed as “abandoned”. Also, when the specification does not change and only the price changes, it is expressed as “funny” in the specification difference item. Has the advantage that the difference between the old and new data can be understood at a glance.

Further, since the price data management device of the present embodiment further provides the connection between the units of information by the serial number, the predetermined information unit is short and the specified price data is one unit. Even if all cannot be expressed, all information can be expressed by connecting a plurality of units. Further, since the upper limit of the serial number is limited, there is no risk that the serial number will be increased indefinitely and information will be diffused.

The present invention is not limited to the above-mentioned embodiment, but can be applied in various ways. For example, although the vehicle has been described in the present embodiment, it goes without saying that the price data management device for other products that simultaneously manages the old and new specification price data can be implemented. Further, in the present embodiment, the management method of two types of specification price data, old and new, has been described, but it goes without saying that it can be applied to management of specification price data of three or more generations.

[0046]

According to the price data management device of the present invention,
Compare the old product price data with the new product price data,
Since it has a creation unit that creates a specification difference item that represents the difference in specifications of the old product price data from the new product price data and a price item that represents the price data based on the specification difference, the old product price Since only the specifications and prices different from the new product price data are stored in the data, the total data amount can be reduced, the capacity of the hard disk, etc. can be reduced, and the price data management device can be made compact. Also, cost reduction can be realized.
