(Constitution)
FIG. 1 is a block diagram showing a hardware configuration of an agrochemical data update device 10 according to an embodiment of the present invention. As shown in the figure, the agrochemical data update device 10 includes a CPU (Central Processing Unit) 11 that controls the pesticide data update device 10 as a whole, a ROM (Read Only Memory) 12 that stores a program executed at startup, A RAM (Random Access Memory) 13 for temporarily storing data, a hard disk device 14 for storing software such as various programs and data, an input device 15 for inputting external data, and various screens are displayed on the display. The display device 16 includes a general computer hardware configuration.

The software stored in the hard disk device 14 includes pesticide data, definition data regarding items and importance handled as keys, a program for narrowing down update target data, a program for updating pesticide data, and the like.
In FIG. 2, an example of the item which comprises agrochemical data is shown. Pesticide data is data indicating the application target of pesticides (applicable pests, applied weeds, applied soil), usage methods (use time, amount of sprayed liquid, number of times), and the like, and is data provided from an external organization. There is no unique key in this pesticide data.

The functional configuration shown in FIG. 3 is realized by the above-described hardware and software included in the agricultural chemical data updating apparatus 10 operating in cooperation. Each function will be described below.
The key item setting unit 101 is composed of definition data stored in a program or database in which key item definitions are described, and sets items to be handled as keys among the items of agricultural chemical data.
Among the items constituting the agricultural chemical data, the specific items “Crop Code”, “Applicable Pest Code”, “Applicable Weed Code”, “Usage Method”, and “Applicable Zone Code” have a hierarchical structure as shown in FIG. Have. Five items having such a hierarchical structure are regarded as temporary keys and used for data comparison (matching).

  The importance setting unit 102 is configured to include importance definition data stored in a program or database in which the definition of importance set in the key item is described. Set. This “importance” indicates the order in which the items are compared with each other. In the present embodiment, a relatively high importance is set for an item having a relatively higher hierarchy, and a value is compared from an item for which a high importance is set.

  Note that the importance setting method is not limited to this, and it is also possible to set a relatively high importance for an item having a relatively lower hierarchy. However, if a relatively high importance level is set for items that are relatively higher in the hierarchy, it is possible to narrow down the items by comparing in stages from the items that are higher in the hierarchy. Data can be narrowed down efficiently in a short time.

The narrowing-down unit 103 compares the items of the agricultural chemical data stored in the hard disk device 14 with the difference data provided from an external institution in order of importance set by the importance setting unit 102, Narrow down pesticide data whose difference data and item values match as update target data.
The item value comparison unit 106 determines whether the item value of the update target data narrowed down by the narrowing unit 103 matches the item value of the difference data.

  When the update unit 104 narrows down the update target data to one, the update unit 104 updates the update target data with the difference data. At the time of this update, the updating unit 104 updates only the value of the item of the update target data that does not match the value of the item of the difference data, based on the comparison result by the item value comparison unit 106. By adopting such an update method, it is not necessary to update records that match the values of matching items or the values of all items, and therefore the update processing time can be shortened.

When there are a plurality of update target data narrowed down by the narrowing-down unit 103, the warning unit 105 outputs the plurality of update target data for warning. Here, as a method of outputting a plurality of update target data, the data is output as a file to the hard disk device 14, and the data output in the file is later printed on paper or displayed on the display device 16. Alternatively, a plurality of update target data may be immediately output to the display device 16 to allow the user to select one update target data.
Note that the functions of the narrowing-down unit 103, the update unit 104, the warning unit 105, and the item value comparison unit 106 are realized by the CPU 11 executing processing according to a program stored in the hard disk device 14.

(flowchart)
Next, the flow of processing performed by the agrochemical data update device 10 will be described with reference to FIG.
First, the agrochemical data update device 10 reads the agrochemical data (hereinafter referred to as “original data”) stored in the hard disk device 14 (step S1).
Next, the agrochemical data update device 10 reads the difference data provided from an external organization from a CD-ROM or the like (step S2).
The narrowing-down unit 103 of the agrochemical data update device 10 performs a process of narrowing down the data to be updated from the original data (step S3). Specifically, the narrowing-down unit 103 narrows down the original data having item values that match the difference data as update target data by comparing the items of the original data and the difference data in the order of the items having the highest importance. .

When the data narrowed down as update target data is one (step S4; Yes), the item value comparison unit 106 compares values for each corresponding item of the narrowed down original data and difference data (step S4). S5).
If there is an item with a different value (step S6; Yes), the updating unit 104 updates the value of the original data item with the value of the difference data item (step S7).
On the other hand, when there are a plurality of data narrowed down as update target data in step S4 (step S4; No), the warning unit 105 outputs the plurality of update target data to another file (step S8).
Note that the processing from step S3 to step S7 may be repeatedly executed for each record of difference data.

(Operation example)
Next, with reference to FIG.6 and FIG.7, the specific operation example at the time of narrowing down update object data from original data is demonstrated.
Here, the difference data shown in FIG. 6A ("Crop code" is "32001000", "Applicable pest code" is "-(space)", "Applicable weed code" is "10000002", "Usage code" The procedure for narrowing down the update target data from the original data shown in FIG. 6B using “10400046” and “Applied zone code” “1”) will be described.
Here, “Crop Code”, “Applicable Pest Code”, “Applicable Weed Code”, “Usage Code”, and “Applicable Zone Code” are selected in advance by the key item setting unit 101 as items handled as keys. It shall be.

  In addition, it is assumed that the importance setting unit 102 sets the importance corresponding to the hierarchical structure for the items handled as these keys. That is, since the items handled as these keys have the hierarchical structure shown in FIG. 4, the highest importance level “1” is set for the item “crop code”, and the item “applicable pest code” is important. Assume that the degree “2” is set and the importance “3” is set for the items “usage code” and “application zone code”.

First, the narrowing-down unit 103 narrows down the original data with the item “crop code” having the highest importance. That is, the narrowing-down unit 103 narrows down the original data of “Crop Code” “32001000” from the original data as update target data. As a result, data narrowed down as update target data is as shown in FIG.
Next, the narrowing-down unit 103 narrows down the item “applicable weed code” whose importance is set to “2” from the data shown in FIG. That is, the narrowing-down unit 103 narrows down the data whose “applicable weed code” is “10000002” from the data shown in FIG. As a result, data narrowed down as update target data is as shown in FIG.

  Next, the narrowing-down unit 103 narrows down items “usage code” and “application zone code” whose importance is set to “3” from the data shown in FIG. 7B. That is, the narrowing-down unit 103 narrows down the data whose “usage code” is “10400046” and “application zone code” is “1” from the data shown in FIG. As a result, the data narrowed down as update target data is as shown in FIG. 7C, and the update target data is narrowed down to one.

  As explained above, by setting the item to be treated as a key for the pesticide data and the importance of the item, and comparing the items of the pesticide data and the difference data in the order of importance of the item to be treated as the key, Since it is possible to narrow down the pesticide data that matches the value of the item to be treated as update target data, the update target data can be uniquely identified even if there is no unique key in the pesticide data, and updated with differential data The target data can be updated.

  In addition, as a result of comparing the corresponding items in the narrowed update target data and difference data, the item value is updated only when there is a mismatched item value, so there is a different item value If not, it is not necessary to perform the update, and the time required for the update process can be shortened. In addition, by outputting a comparison result or update history between the narrowed-down original data and difference data, it is possible to acquire information on changed items.

  The present invention can be used to specify and update update target data for any data that does not have a unique key.
