Description

  The present invention relates to a data processing apparatus, a data processing method, and a program for maintaining data by changing data contents as necessary.

  Recently, a data processing technology (hereinafter referred to as XML technology) based on a meta language (language for creating a language) called XML (eXtensible Markup Language) has attracted attention.

  This XML technology can embed data contents (for example, a category to which each data element belongs) and data structure (for example, arrangement of data elements in data) in a data file, and make the data file visible. The data verification is much easier to perform.

  Here, the language that defines the data structure is referred to as an XML schema. The data element is an individual data element that is surrounded by XML tags and constitutes the entire data.

  Further, in the XML technology, a plurality of existing processors (XML processor or XML parser) for reading an XML document, analyzing a data structure in the XML document, and manipulating data can be used. Therefore, it is possible to construct a highly versatile application. In addition, validity (hereinafter referred to as validity) verification of data as an XML document based on the XML schema can be verified by using an XML processor.

  Here, the above “data as an XML document” is data created based on a database description language (hereinafter referred to as DBL) defined using XML as a meta language, and is defined in DBL. The data structure is recorded as an XML schema. In such data, each data element forms a tree structure with a data element called a root as a base point. Hereinafter, the direction approaching the route may be referred to as the upstream side, and the direction away from the route may be referred to as the downstream side.

Recently, various public systems under computer control have been developed.
Software used in such public systems is generally composed of programs and application data. Here, the program includes data necessary for adapting the generalized program for processing purposes, and the application data is data for associating with a specific environment to which the system is applied.

  In particular, such computer-controlled public systems tend to be more dependent on the application data. Therefore, the importance of system requirements for ensuring the reliability and safety of the application data is increasing.

  However, when such application data includes an error, there is a general possibility that it may become a serious event as a system malfunction. For this reason, data verification for the application data is strictly performed at each stage from the data specification creation stage to the actual machine test stage.

  Conventionally, this data verification is performed manually. Even in the case of using a verification tool, the worker first develops a plurality of dedicated verification tools for each application data, and uses the verification tool to perform data verification on the application data step by step in each of the above steps. Perform multiple times and multiple ways (as many as the number of verification tools) for strictness.

  Therefore, when creating application data based on various specifications with a short delivery time, in order to ensure high reliability and safety by performing the above-mentioned strict data verification multiple times and multiple times for the application data A great deal of labor and cost is required.

  Therefore, recently, attempts have been made to apply the XML technology to the design of the database that is the source of the application data. In this case, the application data means data as an XML document. The application of this XML technology is based on the idea that the validity verification function based on the XML schema is effective in ensuring the reliability and safety of data, as well as the expressiveness and ease of handling of data as XML as a data description language. .

  For example, in Patent Document 1, by using XML technology, even if the mechanism and structure of each database are different, application system design and development costs required for actual operation and modification of the application system when the database is changed A technique related to a general-purpose database access apparatus capable of minimizing costs is disclosed.

  Further, in Patent Document 2, by using XML technology, even when a plurality of telephone exchanges based on different types of control data are provided side by side, each telephone exchange uses such control data. A technology related to an inter-exchange control signal transmission system that can be controlled is disclosed.

  In addition, the XML technology can be used for an automatic train control system (hereinafter referred to as a new ATC system) called a digital ATC (Automatic Train Control) system among railway signal systems.

  According to this new ATC system, an ATC ground device (that is, an ATC device installed on the ground) digitally encodes current position information such as the current position of a preceding train and is based on the MSK (Minimum Shift Keying) method. And transmit to the ATC on-board device (that is, the ATC device mounted on the vehicle) via the rail.

  The ATC on-board device executes a train control program (hereinafter referred to as an ATC on-board device control program), and receives the current position information received via the rail and an on-board DB (hereinafter referred to as an ATC vehicle). Trains such as line segment information (for example, information indicating stop stations, track circuit arrangement, topography, etc.) and vehicle performance information (for example, information indicating brake performance) recorded in the upper DB (Data Base)) A brake pattern indicating a continuous allowable speed is calculated based on control data (hereinafter referred to as ATC on-board DB data), and brake control is performed based on the brake pattern. Note that such brake control in the new ATC system is called “single-stage brake control”.

Therefore, the new ATC system has the following advantages.
1) It is possible to shorten the operation time interval and the arrival time.
2) Since the brake control is performed based on the brake pattern indicating the continuous allowable speed, the shock caused by the brake is alleviated and the riding comfort is improved.
3) Since brake control according to vehicle performance can be easily performed, efficient train operation is possible even in a line section where vehicles with different brake performances are mixed, and the ATC ground equipment has been improved or signaled due to improved brake performance. It is economical because it is not necessary to change the current chart (data for determining the allowable speed).

  In such a new ATC system, the train brake pattern is calculated based on the current position information such as the current position of the preceding train transmitted from the ATC ground device and the ATC on-board DB data stored in the ATC on-board device. Therefore, in particular, the dependence on the ATC on-board DB data is large. The ATC on-board DB data is automatically converted based on the “ATC on-board DB” that centrally manages the entire train control data including data for the ATC ground device. Therefore, in order to ensure sufficient safety in the railway signal, the importance of the system requirement of ensuring reliability and safety for the ATC ground vehicle DB data is very high.

Therefore, recently, the XML technology is applied to the design of the ATC ground vehicle DB in which the ATC ground vehicle DB data is recorded, thereby improving the reliability and safety of the ATC ground vehicle DB data. There is an attempt. In this case, the ATC ground vehicle DB data is created as data as an XML document.

  However, even if application data has been fully verified and has excellent reliability and consistency, if the data contents are changed due to changes in the specification standards, etc. There is a risk that the reliability and consistency may be lost after the change. Therefore, in order for the excellent reliability and consistency of the original application data to be maintained even after the data content is changed, the changed data content should be fully verified. Is indispensable.

Conventionally, verification of the changed data content (hereinafter referred to as verification of the changed content) has been performed manually. That is, the operator extracts the changed part and determines whether only the intended part has been correctly changed.
Hereinafter, a change specification that expresses a change intention by an operator is referred to as a change specification.

  For this reason, after the data content of the application data is changed, in order to maintain the reliability and consistency that the application data originally had after the change, the verification of the changed content must be performed multiple times and It must be done carefully by multiple workers, which requires a great deal of labor and cost.

  In particular, the above-mentioned ATC ground vehicle DB data has a very high frequency of data changes due to diamond changes, etc., but since the change work is manual, as described above, it can be changed quickly and accurately without increasing labor and costs. It is very difficult to carry out the work and maintain the reliability and consistency of the data.

  An object of the present invention is to provide a data processing apparatus, a data processing method, and a program capable of maintaining data so that high reliability and consistency can be maintained even after changing contents without increasing labor and cost.

  Hereinafter, a data processing apparatus 100 to which the present invention is applied will be described in detail with reference to FIGS.

  As will be described in detail below, the data processing apparatus 100 is characterized in that the contents of application data created as an XML document can be changed, and the changed contents can be verified using XSLT (eXtensible Stylesheet Language Transformations).

  Here, XSLT was originally developed as a language for converting the structure of an XML document. Even in general applications, “Structure conversion of an XML document, for example, conversion from an XML document to an HTML document” “Language to do” is dominant. However, the inventors of the present invention can separately acquire each data element in the XML document separately from the intention of the development, and can further refer to, compare, and compare each acquired data element. We found that verification operations such as verification can be performed.

  That is, the present invention utilizes the above-mentioned functions of the XSLT, and the data processing apparatus 100 to which the present invention is applied verifies the change contents using the XSLT for the application data whose contents have been changed. The reliability and consistency of the application data can be maintained later.

  Here, in XSLT, each data element in the XML document is individually acquired based on a path unique to the data element (indicated by XPath).

FIG. 1 shows an internal configuration of the data processing apparatus 100.
As shown in FIG. 1, the data processing apparatus 100 includes a DB 10, a ROM 11, an input unit 12, an output unit 13, a CPU 14, a RAM 15, and the like, and these units are connected to each other by a bus 16.

  The DB 10 includes DB data 102 as application data (for example, control data for controlling the control system), a DB data change work area 101 for designating a change work area for the DB data 102, and the DB data 102. The post-change DB data 103 that has been changed based on the DB data change work area 101, the DB data change location extraction XSLT 104, the DB data change location XSLT extraction result 105, and the DB necessary for verifying the change contents. The data change content verification XSLT 106, the DB data change content XSLT verification result 107, and the XSLT verification result schema 108 are stored.

  Here, the DB data change work area 101, the DB data 102, the post-change DB data 103, the DB data change location XSLT extraction result 105, and the DB data change content XSLT verification result 107 are created as XML documents.

  The ROM 11 stores a program for the CPU 14 to execute the processing shown in the flowchart of FIG. In particular, the ROM 11 includes an XML processor 111 for performing validity verification on the DB data change content XSLT verification result 107 based on the XSLT verification result schema 108, a DB data change location extraction XSLT 104, and a DB data change content verification XSLT 106. Various programs such as the XSLT processor 112 for verifying the contents of the change to the DB data 103 after the change are stored.

  The ROM 11 stores a DBMS (Data Base Management System) application program 113. The DBMS application program 113 prints a form on the DB data 102, outputs the data contents of the DB data 102 in a format that is easy for the operator to view, and changes (corrects input) the DB data 102 manually (or automatically). ) To create the changed DB data 103.

  The input unit 12 includes a keyboard and a pointing device such as a mouse / touch panel (both not shown), and performs various instruction inputs to the data processing apparatus 100 such as an instruction input for changing the DB data 102.

  The output unit 13 includes a printer for printing a form of the DB data 102 and a display device for displaying the data contents when editing the DB data 102 (both not shown).

  The CPU 14 comprehensively controls the data processing apparatus 100 by executing various programs stored in advance in the ROM 11.

  In particular, the CPU 14 executes the process shown in the flowchart of FIG. That is, the CPU 14 executes the XML processor 111, the XSLT processor 112, and the DBMS application program 113, changes the DB data 102, verifies the changed contents, and changes the DB data 103 having reliability and consistency. Create

  The RAM 15 includes a work area for developing the various programs in an executable manner, a memory area for temporarily storing various data, and the like.

  Next, the operation of the data processing apparatus 100 will be described with reference to FIG. The operation of the data processing apparatus 100 described below is performed by the CPU 14 executing a program stored in the ROM 11.

  First, when the data change work type and the data change work range are input by the operator via the input unit 12, the CPU 14 changes the DB data change based on the input data change work type and the data change work range. A work area 101 is created (step S10).

  Here, the data change work type means a data element class to be changed among data elements having a tree structure in the DB data 102, and the data change work range is a subset of the entire data element class. Means. In this description, the data change work area is specified in the order of the data change work type and the data change work range, but the order may be reversed. That is, the change specification is represented in the DB data change work area 101 as the change intention of the worker who performs the change work.

  Thereafter, the CPU 14 executes the DBMS application program 113, performs the change work on the DB data 102 based on the DB data change work area 101, and creates the changed DB data 103 (step S20).

  In this case, by using the DB data change work area 101, it becomes possible to narrow down the change work areas based on the change specifications from the entire DB data 102 in advance, so that the time required for the change work on the DB data 102 can be shortened. . Moreover, the trouble that the change work area which is not contained in change specification among DB data 102 is changed carelessly can be avoided beforehand.

  Note that the change work for the DB data 102 is performed manually by the operator or automatically based on the DB data change work area 101. Even in such a case, the CPU 14 narrows down the change work area for the DB data 102 based on the DB data change work area 101.

  The DB data 102 is changed by the processing in step S20, and the changed DB data 103 is created.

  Here, as specific examples of the DB data change work area 101, the DB data 102, and the post-change DB data 103, the ATC ground vehicle DB data change work area 1011 in the railway signal system, the pre-change ATC ground car DB data 1021, and the change The data contents of the rear ATC ground vehicle on-board DB data 1031 are shown in FIGS. 5, 6, and 7, respectively.

The ATC ground vehicle DB data change work area 1011 is data as a document in XML format, and the data change work range is "" according to the element content of the element indicated by the symbol A1 in the drawing (the element name is "change work range"). Designated as “A station”, and the data change work type is designated as “/ ATC_DB / track circuit set / track circuit / track circuit name” according to the element content of the element indicated by symbol A2 in the figure (the element name is “element path”). Is done.
In this example, the data change work range and the data change work type are specified only one, but a plurality may be specified.

  The pre-change ATC ground vehicle DB data 1021 is data as an XML document having a file name “ATC_DB_ver1.xml”. For each of the three track circuits (that is, track circuits with track circuit IDs “001”, “002”, and “003”), the element names are “track circuit ID”, “track circuit code”, and “track circuit”. Each element of “name”, “downhill”, and “affiliation range” is recorded. Appropriateness of the change type is determined for each element of the element name “track circuit code” and “track circuit name” (or, further, the element name “downhill”) indicated by reference numeral A3 in FIG. The suitability of the changed work range is determined based on the element content of the element name “affiliation range” shown.

  The post-change ATC ground vehicle DB data 1031 (file name is “ATC_DB_ver2.xml”) is obtained by changing the content of the pre-change ATC ground vehicle DB data 1021, and each element indicated by symbol A5 in FIG. Element content has changed.

  Returning to FIG. After step S <b> 20, the CPU 14 executes the XSLT processor 112 based on the DB data 102, the changed DB data 103, and the DB data change location extraction XSLT 104, and extracts all changed locations for the changed DB data 103 at once. Then, this extraction result (that is, all changed portions) is recorded in the DB data changed portion XSLT extraction result 105 (step S21).

  Through the processing of step S21, all changed portions of the changed DB data 103 are extracted.

  Here, as specific examples of the DB data change location extraction XSLT 104 and the DB data change location XSLT extraction result 105, the ATC ground vehicle DB data change location extraction XSLT 1041 and the ATC ground vehicle DB data change location XSLT extraction in the railway signal system The data contents of the result 1051 are shown in FIGS.

  The XSLT 1041 for extracting the ATC ground vehicle DB data change location is related to a predetermined track circuit from the pre-change ATC ground vehicle DB data 1021 by executing each command represented by each element indicated by symbol A6 in the figure. The element contents of each element indicated by reference numeral A3 in the figure (that is, each element whose element name is “track circuit name” and “track circuit code”) are acquired as data having data names “OLD_TR_NAME” and “OLD_TR_CODE”, respectively. Furthermore, by executing each command represented by each element indicated by reference symbol A7 in the figure, the element contents of the element names “track circuit name” and “track circuit code” are changed from the ATC ground vehicle on-board DB data 1021 before the change. For the acquired track circuit, the element contents of the element names “track circuit name” and “track circuit code” are changed to the ATC ground vehicle DB after change. Data name from the over data 1031 "NEW_TR_NAME", are each obtained as the data of "NEW_TR_CODE". Further, by executing a command represented by each element indicated by reference numeral A8 in the figure, it is determined whether or not “OLD_TR_NAME” and “NEW_TR_NAME” do not match (that is, have been changed), and further “OLD_TR_CODE”. ”And“ NEW_TR_CODE ”are determined to be inconsistent (that is, changed), and the element name“ track circuit name ”is shown to indicate that the determination result does not match (that is, has been changed). The element path of the "track circuit code" element content that does not match (that is, the changed one, or both), the track circuit ID of the track circuit and the element content of the element name "affiliation range" At the same time, it is output as the ATC ground vehicle DB data change location XSLT extraction result 1051 (see FIG. 9). The above-described commands represented by the elements A6 to A8 in the drawing are sequentially executed for all track circuits, that is, all track circuits with track circuit IDs “001”, “002”, and “003”.

  The ATC ground vehicle DB data change location XSLT extraction result 1051 is data as an XML document. The track circuit ID is recorded for each track circuit in the element indicated by symbol A9 in the figure, and the element content of the element name “affiliation range” (code A4 in the diagram) is indicated for each track circuit in the element indicated by symbol A10 in the figure. The changed element path is recorded for each track circuit in the element indicated by reference numeral A11 in the figure, and both are output when the ATC ground vehicle DB data change location extraction XSLT 1041 is executed. It has been done.

  Returning to FIG. After step S21, the CPU 14 executes the XSLT processor 112 based on the DB data change work area 101, the DB data change location XSLT extraction result 105, and the DB data change content verification XSLT 106, and verifies the change content for all the change locations. The verification result is recorded in the DB data change content XSLT verification result 107 (step S22).

  By the process of step S <b> 22, it is determined whether all the changed portions extracted in a batch by the process of step S <b> 21 have been changed based on the DB data change work area 101. That is, in the first embodiment, after all the changed portions are extracted in a batch, the verification of the changed contents for all the changed portions is collectively performed.

  Here, as specific examples of the DB data change content verification XSLT 106 and the DB data change content XSLT verification result 107, the ATC ground vehicle DB data change content verification XSLT 1061 and the ATC ground vehicle DB data change content XSLT verification in the railway signal system are shown. The data contents of the result 1071 are shown in FIGS. 10 and 11, respectively.

  In the ATC ground vehicle DB data change content verification XSLT 1061, each command represented by each element indicated by symbol A 12 in the figure is executed, so that from the ATC ground vehicle DB data change work area 1011, the symbol A 1, The element contents of the element names “change work range” and “element path” shown in A2 are respectively acquired as data of the data names “change permission work range” and “change permission element”, and are further denoted by reference numeral A13 in the figure. By executing each command represented by each element, the element contents of the element name “affiliation range” indicated by reference numeral A10 in the figure and related to the predetermined track circuit are extracted from the ATC ground vehicle DB data change location XSLT extraction result 1051. The element contents of the element name “change element” indicated by the middle code A11 are acquired as data of the data names “change work location” and “change element”, respectively. Further, by executing a command represented by each element indicated by reference numeral A14 in the figure, whether the “change-permitted work range” and the “change work range” match (that is, whether the data change work range matches). It is determined whether or not the “change permission element” and the “change element” match (that is, whether the data change work type matches), and the determination result (“OK” or “NG”) is output as the ATC ground vehicle DB data change content XSLT verification result 1071 for each data change work range and data change work type. The above-described commands represented by the elements A12 to A14 in the figure are executed for all track circuits, that is, all track circuits with track circuit IDs “001”, “002”, and “003”.

  The ATC ground vehicle DB data change content XSLT verification result 1071 is data as an XML document. In the element indicated by reference numeral A15 in the figure, the determination result of whether or not the data change work range matches is recorded as “OK” or “NG”, and the data change work type matches the element indicated by reference numeral 16 in the figure. Whether or not the determination result is “OK” or “NG” is recorded, and both are output when the ATC ground vehicle DB data change content verification XSLT 1061 is executed.

  Returning to FIG. After step S22, the CPU 14 executes the XML processor 111 based on the DB data change content XSLT verification result 107 and the XSLT verification result schema 108, and performs validity verification on the DB data change content XSLT verification result 107 (step S23). .

  By the validity verification performed in step S23, it is automatically determined whether or not the change content is completely based on the change specification. When the change contents are completely based on the change specifications, the post-change DB data 103 is used as new DB data 102 having reliability and consistency, and the change contents are completely based on the change specifications. If there is not (that is, incomplete), the data change operation for the incomplete portion specified based on the XSLT verification result schema 108 is performed on the post-change DB data 103 (step S20), and the step continues. The processes of S21 to S23 are executed. Thereafter, the processes in steps S20 to S23 are repeatedly executed until the changed content is completely based on the changed specification.

  Here, as a specific example of the schema for the XSLT verification result, FIG. 12 shows the data content of the ATC ground vehicle DB data change content XSLT verification result schema 1081 in the railway signal system.

  The ATC ground vehicle DB data change content XSLT verification result schema 1081 defines the data structure of the ATC ground vehicle DB data change content XSLT verification result 1071, and the ATC ground vehicle DB data change content XSLT verification result 1071 Whether or not it matches the data structure, that is, whether or not the element content of the element name “verification result” indicated by reference numeral A15 in the ATC ground vehicle DB data change content XSLT verification result 1071 is “OK” This is for verifying validity.

  As described above, the data processing apparatus 100 extracts all changed portions from the DB data 102 and the changed DB data 103 at a time, and then all the changed portions extracted at once are stored in the DB data change work area. The verification of the change contents for determining whether or not the change has been made based on 101 is collectively performed.

Accordingly, it is possible to extract a changed portion from the DB data 102 and the changed DB data 103 without manual intervention, and to determine whether or not the change has been made correctly based on the changed specification, which requires a great deal of labor and cost. The change contents are sufficiently verified, and the reliability and consistency of the entire DB data 103 after the change can be maintained even after the change.
Moreover, since the change location for the DB data 102 is limited in advance based on the DB data change work area 101 and the DB data 102 is changed based on this limitation, the amount of data to be changed can be limited, and the change specification It is possible to avoid a situation in which a part not included in is inadvertently changed.
In addition, since all the changed portions are extracted from the DB data 102 and the changed DB data 103 at once and the verification of the changed contents is collectively performed for all the changed portions, the time required for verifying the changed contents Can be shortened.

  The description in the first embodiment shows an example of the data processing apparatus, the data processing method, and the program according to the present invention, and is not limited to this. The detailed configuration, various numerical values, and detailed operations of the data processing apparatus 100 according to the first embodiment can be appropriately changed without departing from the spirit of the present invention.

  Next, the data processing apparatus 100a to which the present invention is applied will be described in detail with reference to FIGS.

Similar to the data processing apparatus 100 in the first embodiment, the data processing apparatus 100a is characterized in that the contents of application data created as an XML document can be changed and the change contents can be verified using XSLT.
FIG. 3 shows the internal configuration of the data processing apparatus 100a, and FIG. 4 shows a flowchart for explaining the operation of the data processing apparatus 100a.

  Note that among the constituent parts of the data processing apparatus 100a, the same constituent parts as those of the data processing apparatus 100 in the first embodiment are given the same reference numerals for the sake of brevity and description thereof is omitted.

  As shown in FIG. 3, the data processing device 100 a includes a DB 10 a, a ROM 11, an input unit 12, an output unit 13, a CPU 14, a RAM 15, and the like, and these units are connected to each other by a bus 16.

  The DB 10 a includes DB data 102 as application data, a DB data change work area 101 for designating a change work area for the DB data 102, and after the change in which the DB data 102 has been changed based on the DB data change work area 101. The DB data 103, DB data change content verification XSLT 106a, DB data change content XSLT verification result 107 and XSLT verification result schema 108 necessary for reliably verifying the change content are stored.

  The ROM 11 stores a program for the CPU 14 to execute the processing shown in the flowchart of FIG. In particular, the ROM 11 uses the XML processor 111 for performing validity verification on the DB data change content XSLT verification result 107 based on the XSLT verification result schema 108 and the DB data 103 after change using the DB data change content verification XSLT 106a. Various programs such as the XSLT processor 112 for verifying the change contents are stored.

  Next, the operation of the data processing apparatus 100a will be described with reference to FIG. The operation of the data processing apparatus 100a described below is performed by the CPU 14 executing a program stored in the ROM 11.

  First, when the data change work type and the data change work range are input by the operator via the input unit 12, the CPU 14 changes the DB data change based on the input data change work type and the data change work range. A work area 101 is created (step S30).

  Thereafter, the CPU 14 executes the DBMS application program 113, performs the change work on the DB data 102 based on the DB data change work area 101, and creates the changed DB data 103 (step S40).

  In this case, by using the DB data changing work area 101, it is possible to narrow down the changed parts based on the changed specifications from the entire DB data 102 in advance, and therefore the time required for changing the DB data 102 can be shortened. Moreover, the trouble that the location which is not contained in change specification among DB data 102 is changed carelessly can be avoided beforehand.

  Note that the change work on the DB data 102 is performed manually by an operator or automated work based on the DB data change work area 101.

  The DB data 102 is changed by the processing of step S40, and the changed DB data 103 is created.

  Thereafter, the CPU 14 executes the XSLT processor 112 on the basis of the DB data change work area 101 and the DB data change content verification XSLT 106 a, and verifies the change content for the change location from the DB data 102 and the changed DB data 103. This verification result is recorded in the DB data change content XSLT verification result 107 (step S41).

  In the process of step S41, every time each changed place is extracted based on the DB data 102 and the changed DB data 103, the extracted changed place is changed based on the DB data change work area 101. It is determined whether or not That is, in the second embodiment, the extraction of the changed portion and the verification of the changed content with respect to the extracted changed portion are sequentially performed. For example, when the first change portion is extracted, the change contents for the first change portion are verified, and then when the second change portion is extracted, the change contents for the second change portion are extracted. Verification is performed.

  Thereafter, the CPU 14 executes the XML processor 111 based on the DB data change content XSLT verification result 107 and the XSLT verification result schema 108, and performs validity verification on the DB data change content XSLT verification result 107 (step S42).

  By the validity verification performed in step S42, it is automatically determined whether or not the change content is completely based on the change specification. When the change contents are completely based on the change specifications, the post-change DB data 103 is used as new DB data 102 having reliability and consistency, and the change contents are completely based on the change specifications. If not (ie, incomplete), the data change operation for the incomplete portion specified based on the XSLT verification result schema 108 is performed on the post-change DB data 103 (step S40), and the step continues. The process of S41-S42 is performed. Thereafter, the processes in steps S40 to S42 are repeatedly executed until the change contents are completely based on the change specification.

  As described above, the data processing apparatus 100a extracts changed portions from the DB data 102 and the changed DB data 103, and in the process, each time the changed portions are extracted, The change contents for determining whether or not the data has been changed based on the DB data change work area 101 are sequentially verified.

Accordingly, it is possible to extract a changed portion from the DB data 102 and the changed DB data 103 without manual intervention, and to determine whether or not the change has been made correctly based on the changed specification, which requires a great deal of labor and cost. The change contents are sufficiently verified, and the reliability and consistency of the entire DB data 103 after the change can be maintained even after the change.
Moreover, since the change location for the DB data 102 is limited in advance based on the DB data change work area 101 and the DB data 102 is changed based on this limitation, the amount of data to be changed can be limited, and the change specification It is possible to avoid a situation in which a part not included in is inadvertently changed.
In addition, each time a changed part is extracted from the DB data 102 and the changed DB data 103, the contents of the change in the extracted changed part are verified sequentially, so that there is a relatively small memory capacity. Thus, the manufacturing cost of the data processing apparatus 100a can be reduced.

  The description in the second embodiment shows an example of the data processing apparatus, the data processing method, and the program according to the present invention, and is not limited to this. The detailed configuration, various numerical values, and detailed operations of the data processing apparatus 100a in the second embodiment can be appropriately changed without departing from the spirit of the present invention.

  In the first and second embodiments, for example, a plurality of types of XML processors 111 and XSLT processors 112 may be used. As a result, it becomes possible to verify the change contents for the changed portion from the DB data 102 and the changed DB data 103, and to validate the diversity verification of the DB data change contents XSLT verification result 107, thereby further improving reliability and consistency. Improvement is achieved.

  Further, the data processing device 100 or the data processing device 100a may be configured to limit the changeable portions in advance based on the DB data change work area 101 and perform only the process of changing the DB data 102 based on the restriction.

  Further, the data processing apparatus 100 or the data processing apparatus 100a can perform only the process (step S20 or S40) of extracting the changed part from the DB data 102 before the change and the DB data 103 after the change based on the DB data change work area 101. You may do it.
