Abstract

PURPOSE:To improve the efficiency of generation and maintenance of a data value update processing and data processing system by describing the data value update correspondence processing in a production rule of a production system to realize it. CONSTITUTION:When the data value update processing of data from a data value update processing part 1 is performed to update contents of a data storage part 2, it is discriminated whether update report is necessary with respect to updated data or not by a data value update reporting part 3. When it is necessary as the result of discrimination, the update is reported to a data value update history storage part 4 of the production system by the reporting part 3, and data value update information in the storage part 4 is added in the update order. An update correspondence processing determining mechanism of an update correspondence processing part 5 refers to update correspondence processing rules in the storage part 4 and the processing part 5 to discriminate whether execution of the data value update correspondence processing is necessary or not. When it is necessary as the result of discrimination, prescribed data value update correspondence processing is executed by the processing part 5.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of an embodiment of the data value update support processing method of the present invention. a data value update processing unit 1 that updates data values, a data storage unit 2 that stores data values and whether update notification is required for each data item, and updates data values for data items for which update notification is required. A data value update notification unit 3 notifies the data value update history storage unit 4 of the data item name and the updated data value as data value update information when processing is performed, and the data value update processing is performed. A data update history storage unit 4 stores pairs of data items and data values (data value update information) chronologically in the order of update, and a production process is activated when the contents of the data value update history storage unit 4 is changed. The update support processing section 5 executes data value update support processing described in a rule format (described in a production rule).

The data storage section 2 and the data value update notification section 3 are realized by a frame system that has a function of automatically starting a processing procedure (a procedure for changing the contents of the data value update history storage section 4) in response to a data value update. be done.

The data value update history storage unit 4 and the update support processing unit 5 are
This is realized by a production system consisting of working memory (short-term memory), production rules (long-term memory), and an inference mechanism (data value update history storage unit 4).
corresponds to the working memory, the update support processing rules in the update support processing unit 5 (see Figure 3) correspond to the production rules, and the update support processing determination mechanism in the update support processing unit 5 (see Part 3) corresponds to the production rule. (corresponds to an inference mechanism).

FIG. 2 is a diagram showing an example of the configuration of the data storage section 2. As shown in FIG. This data storage unit 2 stores data item names (identification names of data items), data values, and whether update notification is necessary.

FIG. 3 is a diagram showing an example of the contents of the data value update history storage section 4 and the update correspondence processing section 5. As shown in FIG. The data value update history storage unit 4 stores pairs of data item names and data values of updated data (data value update information) in chronological order. Further, this update support processing unit 5
THEN ~” format for data value update support processing (processing pt
and P2 corresponds to the data value update support processing), and the data value update history storage unit 4 and I in each rule of the update support processing rule.
F part and select a rule that has the data item name of the data whose data value has been updated most recently in the IF part and the content of the IF part matches the content of the data value update history storage unit 4, and selects the rule. T) an update handling process determination mechanism that executes the iEN part processing (data value update handling process).

Referring to FIG. 4, the processing of the data value update corresponding processing method of this embodiment includes a data value update processing step 4I, an update notification necessity determination step 42, an update notification step 43, and a data value update corresponding processing necessity determination. Step 44 and data value update corresponding processing step 45 (this flowchart shows the flow of processing caused by one data value update) Next, the data of this embodiment configured as described above is The operation of the value update compatible processing method will be explained. Here, we will explain the operation when the data storage unit 2, data value update history storage unit 4, and update support processing unit 5 have the contents as shown in FIGS. 2 and 3 (data whose item name is C (data C) Operation resulting from the data value being updated to 01) will be explained.

When the data value update process (process of updating the data value to 01) of data C is performed by the data value update processing unit 1 and the contents of the data storage unit 2 are updated (step 41), regarding the updated data C. The data value update notification unit 22 determines whether or not an update notification is necessary based on the reference to the data storage unit 2 (step 42).

If an update notification is necessary in this determination (this is the case in this example, since the necessity of an update notification regarding data C in the data storage unit 2 is "Yes"), a data value update notification is sent. The update notification (notification of data value update information consisting of a data item name and the updated data value) is performed by the data value update history storage unit 4 by the data value update history storage unit 4, and the data value in the data value update history storage unit 4 is updated. Update information is added (thereby, the data value update history storage unit 4 has contents as shown in FIG. 3) (step 43).

The update support process determination mechanism in the update support processing unit 5 uses the update support processing rules (as shown in FIG. The update-compatible processing rule (which describes rule 1 that says "When data A and data C are updated, execute process P1" and rule 2 that states that "when data A and data C are updated, execute process P2") is referred to and the data is updated. It is determined whether or not it is necessary to execute the value update corresponding processing (processing pi and P2) (step 44).

In this example, since data C is the latest updated data, rule 2 that has data A and data C in the IF part is selected, and since both data A and data C have been updated, processing P2 of THEN part is required. It is determined that there is.

If data value update support processing is necessary in the determination at step 44 (as described above, this is the case in this example)
, a predetermined data value update support process (in this example, process P2) is performed by the update support process determination mechanism in the update support processing unit 5.
is executed (step 45), and control returns to the determination in step 44 (as described above, when process P2 is executed in step 45, the condition of the IF part of rule 2 is no longer satisfied). If update notifications are not required (for example,
Due to the update of data D (see FIG. 2), step 42
) or if the determination in step 44 is that the data value update corresponding process is not necessary (for example, in this example, if the determination in step 44 is performed again after process P2 is executed in step 45) ), the processing of the data value update corresponding processing method of this embodiment, which is caused by one data value update process (processing by the data value update processing unit 1), ends.
