Description

  The present invention relates to a data capturing system for capturing data.

  Various businesses are carried out in companies and the like, and a computer system for managing the business execution is used. This computer system is generally called a business system. In a business system, in various situations such as system updates, the data managed by the business system is output as a data file in a predetermined data format (data format) such as text format according to the arrangement of the predetermined data items. Data is read by reading the output data file.

  When capturing data, there is a possibility that the same data will be captured again even though the same data has already been captured. In particular, since the business system is used by a plurality of users, there is a possibility that another user may capture the same data even though one user has already captured it.

  Therefore, a system for preventing duplicated data capture is disclosed in Patent Document 1 below.

Japanese Patent Laying-Open No. 2006-1264889

  In the system disclosed in Patent Document 1, since data in a data file is directly compared, it takes time to determine whether to take duplicates, which takes time for data fetching. In addition, for comparison, it is necessary to hold the data file to be imported or all the data, and there is a problem that the storage capacity is pressed.

  Therefore, in view of the above problems, the present inventor has made it possible to reduce the time required for the duplicate capture determination process, and to eliminate the need to retain the data file or data to be captured, thereby saving the storage capacity. Invented the system.

A first invention is a data capturing system for capturing data, the data capturing system storing identity identification information based on a data file describing data that has been captured or is being captured. Refer to the acquisition history information storage unit for whether there is identity identification information that matches the identity identification information generated based on the data file describing the data to be acquired and the data to be acquired. A comparison processing unit that performs comparison, and when the comparison processing unit determines that there is no matching identity identification information, a capture processing unit that executes data capture processing of the data file to be captured; A warning processing unit for displaying a predetermined warning when the comparison processing unit determines that there is matching identity identification information, and the warning processing unit is a result of the warning display. , When accepting the selection of continuing the write process, again, in terms of executing the comparison process identity identification information in the comparison processing unit, executes the acquisition process in the acquisition processor, by the data acquisition system is there.

As in the present invention, identity identification information based on a data file describing data that has already been captured or being captured is stored as a capture history, and the identity identification information in the capture history and the capture target Retains the data file to be imported or all data by judging whether duplicate registration is performed by comparing whether the identity identification information generated based on the data file that describes the data to be matched matches There is no need to keep it. In addition, the processing time for determination (comparison) of duplicate capture can be shortened. As a result, the time required for data acquisition can be shortened and the storage capacity can be saved.
Further, by configuring as in the present invention, the user can be alerted when data having the same content is fetched.
Furthermore, even if the data has already been captured, there are cases where it is desired to retrieve again due to various circumstances such as forgetting to save the data or deleting the data. In this case, the capturing process may be executed as it is, but it is preferable to execute the identity identification information comparison process again before capturing. This is because another user may be performing the process of capturing the same data after the comparison process and before the operation for continuing the capture process for the warning.

In the above-described invention, when the warning processing unit accepts the selection of continuing the capture process as a result of the warning display, the operation date and time of the capture history corresponding to the identity identification information that matched in the previous comparison. It can be configured as a data fetching system in which the comparison process of the identity identification information in the comparison processing unit is executed again with the later date and time as a comparison target .

Even if the data has already been captured, there are cases where it is desired to retrieve the data again due to various reasons such as forgetting to save the data or erasing the data. In this case, the capturing process may be executed as it is, but it is preferable to execute the identity identification information comparison process again before capturing. This is because another user may be performing the process of capturing the same data after the comparison process and before the operation for continuing the capture process for the warning.
In that case, in the comparison process again, the date and time after the operation date and time of the capture history corresponding to the identity identification information matched in the previous comparison is set as the comparison target. The problem when continuing the capture process is that there may be another user capturing the same data between the previous comparison process and the continuous capture process for the warning. This is because it is sufficient to compare only the acquisition history during that period. This can prevent unnecessary comparison processing and warning display.

In the above-described invention, the data capturing system receives a data file specification that describes the data to be captured, and performs a preprocessing on the data file that has received the specification. It can be configured like a data acquisition system having

In the above invention, the data capture system may be configured as a data capture system that deletes the capture history when the capture history stored in the capture history information storage unit is zero. it can.

In the above invention, the data capture system performs error checking on the data to be captured before executing the data capture process of the data file to be captured in the capture processing unit. It can be configured like a data acquisition system that executes processing.

  In the above-described invention, the comparison processing unit can be configured as a data capture system that performs exclusive control that prevents the capture processing in the capture processing unit during the comparison process.

  If another user takes in data having the same contents while the comparison process is being performed, a comparison omission occurs, resulting in duplicate registration. Therefore, as in the present invention, it is possible to prevent the occurrence of comparison omission by performing exclusive control that does not perform the capture process during the comparison process.

  In the above-described invention, the data capture system further includes an identity identification information generation processing unit that generates identity identification information based on data of a data file to be captured. The identification information is a hash value generated by a hash function, and can be configured as a data capturing system.

  It is preferable to use a hash value as the identity identification information.

  The data capture system in each of the above-described inventions may function as one function of the business system.

The data fetching system of the first invention can be realized by reading the program of the present invention into a computer and executing it. In other words, the computer describes whether or not there is identity identification information that matches the identity identification information generated based on the data file that describes the data to be imported. A comparison processing unit for comparing with reference to an acquisition history information storage unit that stores identity identification information based on a data file, and if the comparison processing unit determines that there is no matching identity identification information, An import processing unit that executes an import process of data of a target data file, an alert processing unit that displays a predetermined alert when it is determined that there is matching identity identification information in the comparison processing unit, be made to function a data acquisition program characterized as the warning processing unit, the warning display results, it accepts the option of continuing the acquisition process again On executing the comparison process identity identification information in the comparison processing unit, executes the acquisition process in the acquisition process unit, a data acquisition program.

  In the data capture system of the present invention, the identity identification information based on the data file to be captured is compared. Therefore, compared with the prior art such as direct comparison of data, duplicate capture determination processing is performed. It can be done in a short time. Therefore, it is possible to save the storage capacity by shortening the time required for the data fetching process and eliminating the need to hold the data file or data to be fetched.

  An example of the system configuration of the data acquisition system 1 of the present invention is schematically shown in FIG. An example of a hardware configuration of a computer on which the data capturing system 1 functions is schematically shown in FIG. Although FIG. 1 shows a case where the functions of the data capturing system 1 are divided into the user terminal 3 and the server 2, each function of the data capturing system 1 can be functioned by a single computer. Alternatively, each function may function as appropriate with a plurality of computers. Each means in the present invention is only logically distinguished in function, and may be physically or virtually the same area.

  The data capture system 1 preferably functions as one function of a business system (not shown), but can also function in cooperation with a system different from the business system or independently. A business system is a computer system for managing business execution of a company. There are various business systems, and there are no limitations. For example, a computer system for performing personnel, salary, financial accounting, sales, purchasing, etc. is an example. The business system may be incorporated in the groupware system. A groupware system is a computer system for managing business operations of a company, and supports the work of multiple people by sharing information using a computer network in the company. It is a computer system. There are various types of groupware systems, and there is no limitation.

  The server 2 and the user terminal 3 in the data capturing system 1 are realized by a computer. The computer includes an arithmetic unit 70 such as a CPU for executing arithmetic processing of a program, a storage unit 71 such as a RAM and a hard disk for storing information, a display unit 72 such as a display, a keyboard and a pointing device (such as a mouse and a numeric keypad). And a communication device 74 that transmits and receives processing results of the arithmetic device 70 and information stored in the storage device 71 via a network such as the Internet or a LAN.

  The business system of the present invention is used in various organizations such as corporations, associations, foundations, schools, and the like. As the business, a business suitable for each organization can be used.

  The data capture system 1 includes a data file designation processing unit 31, an identity identification information generation processing unit 32, a capture history information storage unit 21, a reception processing unit 22, a comparison processing unit 23, a capture processing unit 24, and a warning processing unit. 25.

  The data file designation processing unit 31 accepts designation of a data file (for example, a text file) that describes data to be imported. The data file specification processing unit 31 performs preprocessing on the data file after receiving the specification of the data file and before generating the identity identification information in the identity identification information generation processing unit 32 described later. You may go. As preprocessing, for example, if the data file is a text file consisting of multiple lines (one line is one data or multiple lines is one data), each line is extracted and converted to multiple data. Blank lines are deleted from the data file And processing such as creating a new data file. In the former case, identity identification information can be generated for each piece of data. In the latter case, even if the data files differ only in blank lines, they can be determined as the same file. Even when one row is not one data, such as when one row has one data, it can be converted into a plurality of data, for example, by allowing the user to specify the range of one data.

  The identity identification information generation processing unit 32 generates identity identification information based on the data file that has been designated by the data file designation processing unit 31. For example, a hash value is generated using a hash function for data described in a data file that has received a specification. In this case, the hash value becomes the identity identification information. The identity identification information based on the data file does not include metadata such as the file name or update date of the data file, and the data file data itself (part or all of the data described in the data file) is used as an argument. A value generated by calculating with a predetermined function such as a hash function. The function is preferably injective, but is not limited thereto. If the data file is a text file describing data composed of a plurality of lines (one line is one data or a plurality of lines is one data), processing for generating identity identification information may be executed for each data. .

  The acquisition history information storage unit 21 stores a data acquisition history. It is preferable to store the acquisition history of the acquired data and the acquisition history of the data being acquired. FIG. 4 schematically shows an example of the acquisition history information storage unit 21. The import history includes the operation date and time (capture date and time), login ID (user identification information of the user who performed the capture operation), and status information indicating whether or not data has been captured ("Updated" is Imported, "Updating" is being imported), identity identification information (hash value, etc.), file name (file identification information of the data file that describes the data to be imported), file date and time (data file itself that describes the data to be imported) However, the present invention is not limited to these.

  It should be noted that there are cases in which the data described in the data file cannot be normally taken in due to various circumstances after the take-in process in the take-in processing unit 24 to be described later. In this case, the number of imports is 0. Therefore, when the number of captures is 0, it is more preferable to delete the capture history. In other words, there is a possibility that processing is performed even for data files that are all blank lines or data files that do not conform to the layout assumed by the capture processing side. When the data of such a data file is captured, the actual number of captures is 0 because the data cannot actually be captured. On the other hand, even in the case of such data files, the identity identification information is generated, and the capture history remains. And if you keep such import history, when you try to import the data of the same data file again, a warning indicating that it has already been captured is displayed. In spite of the absence, the user may be misunderstood as if it was captured. Therefore, when the number of captures is 0, the capture history is deleted.

  The reception processing unit 22 receives the data or data file described in the data file whose specification is received by the data file specification processing unit 31 and the identity identification information generated by the identity identification information generation processing unit 32. In addition, it is preferable that the reception processing unit 22 receives data of the data file whose specification is received by the data specification file specification processing unit 31 from the user terminal 3. This can reduce network bandwidth pressure and server load. Therefore, the user terminal 3 reads the data file that has been designated by the data file designation processing unit 31 and transmits the data described in the data file to the server 2. The data transmission may be performed by transmitting a plurality of data collectively. For example, when the data is a data file composed of a plurality of rows (one row is one data or a plurality of rows is one data), the data may be transmitted every predetermined row.

  The comparison processing unit 23 compares the identity identification information received by the reception processing unit 22 with the identity identification information stored in the acquisition history information storage unit 21, and determines whether there is matching identity identification information. judge. Note that if the same data acquisition process is started during the comparison check, there is a possibility of duplicate registration. Therefore, before performing the identification identification information comparison process, it will be described later. The capture processing in the capture processing unit 24 is temporarily stopped (exclusive control is started), and after completion of the comparison processing, the capture processing in the capture processing unit 24 is resumed (exclusive control is terminated).

  If there is no identity identification information that matches the acquisition history information storage unit 21 as a result of comparison in the comparison processing unit 23, the acquisition processing unit 24 operates the operation date and time, the operator (the user who performed the data acquisition operation) , User identification information), identity identification information, file name, file date and time, and the like are stored in the acquisition history information storage unit 21. In addition, a process of fetching data received by the reception processing unit 22 or data described in the data file is executed.

  The warning processing unit 25 displays a warning screen when there is matching identification information in the acquisition history information storage unit 21 as a result of the comparison in the comparison processing unit 23. In this case, a part or all of the acquisition history in the acquisition history information storage unit 21 may be displayed on the warning screen. In this warning screen, it is notified that the data of the same content has already been taken in or is being taken in, and the selection of whether or not to continue the fetching process is accepted. When the selection to continue is accepted, the capture processing in the capture processing unit 24 is executed. At this time, the comparison processing of the identity identification information in the comparison processing unit 23 may be executed again. However, since the comparison target in this case is for the possibility that another user is taking in the same data after the warning screen is displayed, the identity identification information matched in the comparison process in the previous comparison processing unit 23 is The comparison process is executed for the identity identification information after the corresponding operation date.

  When the warning processing unit 25 receives a selection to cancel on the warning screen, the warning processing unit 25 stops the capture process.

  Next, the processing process of the data capturing system 1 of the present invention will be described with reference to the flowchart of FIG. It is assumed that the acquisition history information storage unit 21 before the start of processing is in the state shown in FIG.

  A user (USER_C) who desires to take in data executes a predetermined operation on the user terminal 3. When this operation is performed on the user terminal 3, the data file designation processing unit 31 displays the capture screen shown in FIG. FIG. 5 shows an example of an import screen for importing journal entries.

  The user designates a data file describing data to be captured by performing a predetermined operation on the capture screen (S100). An example of an import screen in a state where a data file is designated is shown in FIG. FIG. 6 shows a state in which the data file “20170924.txt” on the desktop of the user terminal 3 of the user (USER_C) is designated.

  Then, when the user presses the “execute” button on the capture screen, the identity identification information generation processing unit 32 uses the hash function for the data file “20170924.txt” specified in S100 to generate a hash value. Is generated (S110). Assume that the hash value generated here is “A01DD213B9...”. The hash function calculates a hash value using a data file as an argument.

  Then, the data file designation processing unit 31 sends the data file “20170924.txt” designated in S100 and the hash value “A01DD213B9...” Generated by the identity identification information generation processing unit 32 to the server 2, 2 accepts the data described in the data file “20170924.txt” and the hash value “A01DD213B9...” (S120). At this time, the file name “20170924.txt” of the designated data file and metadata, for example, the update date of the file “20170924172045” are sent from the user terminal 3 to the server 2 and received by the reception processing unit 22 of the server 2. .

  When the data and the hash value are received in S120, the comparison processing unit 23 starts exclusive control (S130), and the same hash value as the received hash value “A01DD213B9...” Is stored in the acquisition history information storage unit 21. The stored information is compared (S140). It is determined that there is no matching hash value in the acquisition history information storage unit 21 in FIG. Then, after the comparison process is finished, the exclusive control is finished (S150).

  Here, since the same hash value is not stored in the acquisition history information storage unit 21 (S160), the acquisition processing unit 24 determines the operation date and time, the operator (the user identification of the user who performed the data acquisition operation). Information), hash value “A01DD213B9...”, File name “20170924.txt”, file date and time “20170924172045”, and the like are stored in the acquisition history information storage unit 21. An example of the capture history information storage unit 21 in this state is shown in FIG. Then, the data file “20170924.txt” is fetched (S170).

  As described above, the import of data described in the data file can be completed normally.

  Next, a case where another user (USER_A) loads a data file having the same content (same data) as the previous user (USER_C) will be described.

  The user (USER_A) executes a predetermined operation on the user terminal 3 to display the capture screen (FIG. 5). Then, a data file that describes data to be imported is designated (S100). FIG. 8 shows an example of an import screen in a state where the user (USER_A) designates a data file. FIG. 8 shows a state in which the data file “0924 purchase.txt” on the desktop of the user terminal 3 of the user (USER_A) is designated.

  Then, when the user (USER_A) presses the “execute” button on the capture screen, the identity identification information generation processing unit 32 applies a hash function to the data file “0924 purchase.txt” specified in S100. Using this, a hash value is generated (S110). Assume that the hash value generated here is “A01DD213B9...”.

  The data file specification processing unit 31 sends the data file “0924 purchase.txt” specified in S100 and the hash value “A01DD213B9...” Generated by the identity identification information generation processing unit 32 to the server 2. , The reception processing unit 22 of the server 2 receives the data described in the data file “0924 purchase.txt” and the hash value “A01DD213B9...” (S120). At this time, the file name “0924 purchase.txt” of the specified data file and metadata, for example, the file update date and time “20170924172045” are sent from the user terminal 3 to the server 2, and the reception processing unit 22 of the server 2 is sent. Accept.

  When the data and the hash value are received in S120, the comparison processing unit 23 starts exclusive control (S130), and the same hash value as the received hash value “A01DD213B9...” Is stored in the acquisition history information storage unit 21. The stored information is compared (S140). It is determined that there is a matching hash value in the capture history information storage unit 21 in FIG. Then, after the comparison process is finished, the exclusive control is finished (S150).

  Here, since the same hash value is stored in the acquisition history information storage unit 21 (S160), the warning processing unit 25 sends part or all of the acquisition history determined to be the same to the user terminal 3. The feed and warning screen is displayed (S180). FIG. 9 shows an example of the warning screen.

  By viewing this warning screen, the user can recognize that a data file having the same contents (same data) has been captured. When canceling the capture process (S190), by pressing “No” on the warning screen, information for canceling the capture process is sent from the user terminal 3 to the server 2, and the server 2 captures the capture process. Cancel processing.

  On the other hand, even if a data file having the same contents has already been captured, there are cases where it is desired to retrieve the data again due to reasons such as forgetting to save the data or deleting it by mistake. In such a case, since the capturing process is continued (S190), "Yes" on the warning screen is pressed. When “Yes” is pressed, information for continuing the capture process is sent from the user terminal 3 to the server 2, and the comparison processing unit 23 of the server 2 executes the comparison process again.

  At this time, the comparison processing unit 23 first operates as the comparison target of the comparison process, the operation date and time (capture start date and time) of the capture history corresponding to the identity identification information that matched in the previous comparison (September 2017). The date and time after 19:08:13 on March 24 is set as a comparison target (S200), and exclusive control is started (S130). Then, the acquisition history information storage is performed at a date after the operation date and time (capture start date and time) (September 24, 2017 19:08:13) corresponding to the identity identification information matched in the previous comparison process. It is compared whether there is identity identification information that matches the part 21 (S140). And exclusive control is complete | finished (S150).

  Here, since there is no matching identity identification information (S160), the capture processing unit 24, the operation date and time, the operator (user identification information of the user who performed the data capture operation), the hash value “A01DD213B9. “”, File name “0924 purchase.txt”, file date and time “20170924172045” and the like are stored in the acquisition history information storage unit 21. An example of the capture history information storage unit 21 in this state is shown in FIG. Then, the data file “0924 purchase.txt” is fetched (S170). Until the capturing process is completed, “updating” indicating that the capturing is being performed is stored as the “state”. Then, after the acquisition process is completed, the “status” is changed from “during acquisition” to “updated” indicating that the acquisition is completed, and stored. An example of the capture history information storage unit 21 in this state is shown in FIG.

  As described above, even if the data files have the same contents, the importing of data described in the data file can be completed normally.

  Next, as a different embodiment of the first embodiment, the error check process may be executed before the data fetch process of the first embodiment is executed. The error check process is a process for checking whether it is suitable for the arrangement of data items in the business system using the captured data and whether the data format is the same.

  Even when the error check process is performed, the comparison process can be executed using the identity identification information in the same manner as in the first embodiment.

  In this case, the data file to be processed for error check is specified on the capture screen of the user terminal 3 (S100). When the “error check” button on the capture screen is pressed, the identity identification information generation processing unit 32 generates a hash value for the specified data file using a hash function (S110). .

  Then, the data file specification processing unit 31 sends the specified data file and the hash value generated by the identity identification information generation processing unit 32 to the server 2, and the reception processing unit 22 of the server 2 outputs the data and hash value. Accept (S120).

  When the reception processing unit 22 of the server 2 receives the data and the hash value, the comparison processing unit 23 starts exclusive control (S130), and the same hash value as the received hash value is stored in the acquisition history information storage unit 21. The stored information is compared (S140). Then, after the comparison process is finished, the exclusive control is finished (S150).

  When the same hash value is not stored in the acquisition history information storage unit 21 (S160), a data check process in the data file is executed (S170). If the same hash value is stored in the acquisition history information storage unit 21 (S160), the warning screen shown in FIG. 9 is displayed, and the processing after S180 is executed as in the first embodiment. .

  The timing at which the identity identification information generation processing unit 32 generates the identity identification information is not limited to that in the first and second embodiments. For example, when the file is specified, the identity identification information generation processing unit 32 is transmitted from the user terminal 3 to the server 2. It can be executed at any timing before the comparison processing in the comparison processing unit 23, such as the stage, the stage received by the server 2, or immediately before the processing in the comparison processing unit 23.

  By using the data capture system 1 of the present invention, the identity identification information based on the data in the data file to be captured is compared, and therefore compared with the prior art such as when directly comparing data. Acquisition judgment processing can be performed in a short time. Therefore, it is possible to save the storage capacity by shortening the time required for the data fetching process and eliminating the need to hold the data file or data to be fetched.
