Description

  The present invention relates to an information processing apparatus, an information processing system, a control method thereof, and a program.

  A web service is known as a mechanism for calling and using an application running on a server from an application on a client device. The Web service is a method of transmitting and receiving a message using an XML (Extensible Markup Language) format protocol called SOAP (Simple Object Access Protocol) by applying Internet-related technology such as HTTP (HyperText Transport Protocol). It is.

  In a Web service client (client application) that invokes a Web service, what method is disclosed by the publicly available WSDL (Web Services Description Language / Web service) and what URI is to be accessed In many cases, a proxy class file generated based on an XML file in which information such as what parameters are to be passed, what is a return value, and what namespace is to be used is described. The proxy class is a Web service calling program that plays a role in a client that can access an application running on a server via the Web in the same way as accessing a local library.

  When the specification of the Web service is changed, the WSDL that is published to use an application (server application) that runs on the server is also changed. Therefore, the proxy class generated from WSDL is changed and used in the client application. Japanese Patent Application Laid-Open No. 2004-228561 describes a method of detecting a WSDL change and automatically changing a proxy class in response to the change of the Web service. However, since the technique of the cited document 1 cannot dynamically change the client application program that calls the proxy class, the user needs to modify the client application program itself. In order to alleviate this trouble, Patent Document 2 discloses that a mapping file template is generated from WSDL and mapping by manual input by a user (data items of data model definition and INPUT and OUTPUT of a Web service described in WSDL). The technology that enables the user to enjoy the web service without changing the client application program is disclosed.

  Hereinafter, an example of an embodiment of the present invention will be described with reference to the drawings.

<First Embodiment>
First, a first embodiment of the present invention will be described with reference to FIGS.

  The present invention provides a mechanism that allows easy mapping of items related to Web services.

  For example, a mechanism that can update a mapping file by an intuitive data movement operation such as drag and drop is provided.

  First, an example of the configuration of an information processing system in the embodiment of the present invention will be described with reference to FIG.

  As shown in FIG. 1, in the information processing system of the present invention, various apparatuses such as a program development PC 100, PC 101, application server 200, and Web service providing server 300 can communicate via a network such as a WAN 150 (wide area network). Connected and configured.

  The program development PC 100 causes a program development application (an application generation unit 410 in FIG. 4) on the program development PC to operate on its own device by a user operation, and executes each process of a flowchart described later.

  The web service providing server 300 publishes / provides a web service and uses the web service as an external device / external application (for example, an application running on the application server 200 / a client application for the web service). WEB service description language file).

  The program development PC 100 downloads and acquires the WSDL of the Web service provided by the Web service providing server via the WAN 150, and uses the mapping file and the proxy class (Web service) according to the method described in JP2011-059751A. A calling program). Also, the mapping file is updated using a data model (also referred to as a data model definition) stored in the own device in accordance with a user operation. Then, the mapping file after mapping and the Web service calling program are transmitted to the application server, thereby enabling (deploying) the use of the Web service by the application (Web application) operating on the application server.

  The mapping file in this embodiment is an association file that associates the data model on the Web application side (client application side) with the input / output data items of the Web service. A data model used by a database managed by the web application itself and created exclusively for the web application completely matches the schema of the database. However, in a mechanism that uses a Web service, the data model used by the Web application does not necessarily match the input / output data items of the Web service. This is because, for example, the company that designs and manages the Web application and the Web service is different, or the design concept and data management rules are different. The mapping file is responsible for associating the data model with the input / output data items of the web service, and associates the data model item with the input data or output data of the web service (input / output data items published by WSDL). This is called mapping.

  The application server 200 includes a Web application that executes processing and functions in response to an operation instruction from an external device such as the PC 101. Further, for example, the argument data model is determined and input as an input value (input parameter) to the Web service calling program with reference to the mapping file. The Web service calling program converts the input value into a SOAP message and transmits the SOAP message to the Web service program of the Web service providing server 300. The Web application in which the data model of the return value obtained as a response is mapped to the mapping file It is applied to the data model handled by and is output to the Web application. In other words, even if the Web service specification (WSDL specification) is changed, the Web service can be used in response to the Web service specification change by changing the mapping file without changing the Web application program. It is configured. The above is the description of FIG.

  Next, an example of the hardware configuration of various devices in the embodiment of the present invention will be described with reference to FIG.

  In FIG. 2, reference numeral 201 denotes a CPU that comprehensively controls each device and controller connected to the system bus 204. Further, the ROM 202 or the external memory 211 is necessary to realize a BIOS (Basic Input / Output System) or an operating system program (hereinafter referred to as an OS), which is a control program of the CPU 201, or a function executed by each server or each PC. Various programs to be described later are stored.

  A RAM 203 functions as a main memory, work area, and the like for the CPU 201. The CPU 201 implements various operations by loading a program or the like necessary for execution of processing from the ROM 202 or the external memory 211 into the RAM 203 and executing the loaded program.

  An input controller 205 controls input from a keyboard (KB) 209 or a pointing device such as a mouse (not shown). A video controller 206 controls display on a display device such as a display 210 (for example, a CRT display). The display device may be not only a CRT display but also other display devices such as a liquid crystal display. These are used by the user as needed.

  A memory controller 207 is connected to the hard disk (HD), flexible disk (FD), or PCMCIA card slot for storing a boot program, various applications, font data, user files, editing files, various data, etc. via an adapter. The access to the external memory 211 such as a compact flash (registered trademark) memory is controlled.

  A communication I / F controller 208 is connected to and communicates with an external device via a network (for example, the WAN 150 and the LAN 151 shown in FIG. 1), and executes communication control processing in the network. For example, communication using TCP / IP is possible.

  Note that the CPU 201 enables display on the display 210 by executing outline font rasterization processing on a display information area in the RAM 203, for example. Further, the CPU 201 enables a user instruction with a mouse cursor (not shown) on the display 210.

  Various programs to be described later for realizing the present invention are recorded in the external memory 211 and executed by the CPU 201 by being loaded into the RAM 203 as necessary. Furthermore, definition files and various information tables used when executing the program are also stored in the external memory 211, and a detailed description thereof will be described later. The above is the description of FIG.

  Next, an example of a functional configuration of the program development PC in the embodiment of the present invention will be described with reference to FIG. The functions 301 to 306 are functions provided in the program development application installed in the program development PC 100. The CPU 201 of the program development PC 100 executes processing of a flowchart described later using each function of the program development application.

  The mapping file display processing unit 301 is a processing unit that displays mapping file information on the mapping file display unit 1009 in response to a user operation, for example, on a mapping file display screen as shown in FIG. The data model display unit 302 is a processing unit that displays the data model definition (1001 in FIG. 10) read from the external memory on the display screen, as indicated by 1008 in FIG. The move operation accepting unit 303 accepts a data move operation by a drag-and-drop operation or the like for the mapping file editing unit (1002 in FIG. 10) displayed by the mapping file display processing unit 301.

  The data model determination unit 304 determines whether data that has been moved (drag and drop) has a data model definition. When the data subjected to the movement operation is a data model definition, the mapping target item determination unit 305 displays an input / output data item (input data item (INPUT) or input data item) of the mapping file displayed in the editing unit 1002 of the movement destination. The item name (character string of identification information) of the output data item (OUTPUT)) is matched with a predetermined data item name in the data model definition for which the move operation has been performed, and the items having the same item name are associated with each other That is, it is a processing unit that decides to perform mapping. The mapping file generation unit 306 generates a mapping file in which the items determined to be associated are mapped on the external memory according to the determination by the mapping target item determination unit 305. For example, information on the mapping file displayed in the destination (editing unit 1002) stored in the external memory and displayed on the destination is read onto the memory, and the mapping target item determining unit 305 is stored in the mapping file. By mapping the items determined by the above, overwriting and updating, a mapping file after mapping by the moving operation is generated. The above is the description of FIG.

  Next, with reference to FIG. 4, the functional configuration of various apparatuses and the location of data in the embodiment of the present invention will be described.

  FIG. 4 is a configuration diagram of various devices of the information processing system according to the embodiment of the present invention. In addition, description of 301-306 mentioned above in description of FIG. 3 is abbreviate | omitted.

  The program development PC 100 holds a repository definition unit 400, an application generation unit 410, a Web application infrastructure code generation unit 420, a Web service call module generation unit 430, a mapping file editing unit 440, and a source code compilation unit 450.

  The repository definition unit 400 includes an application definition 401, an input / output definition 402, a data model definition 403, a business process definition 404, an extension definition 406, and a mapping file 407. These files are input by a developer through a program development application, created, and stored on the external memory of the program development PC 100.

  That is, the repository definition unit 400 defines Web application input definition information that defines items input as arguments for executing a program, and Web application output definition information that defines items to be output as processing results of executing the program. Is an example of a means for managing I / O as input / output definition information for a Web application. The web application here refers to a web application (461 in FIG. 4) held by the application server 200.

  Next, the Web application base code generation unit 420 will be described. The repository definition analysis unit 421 reads and analyzes the application definition 401, the input / output definition 402, the data model definition 403, the business process definition 404, the extension definition 406, the mapping file 407, and the like from the repository definition unit 400. The web application code generation unit 422 uses the code generation rules stored in the external memory 211 and the contents analyzed by the repository definition analysis unit 421, via the source code compilation unit 450, and a web application module (web application). Program). That is, the Web application code generation unit 422 is an example of a unit that stores a rule for generating a program used for a Web application.

  The WSDL analysis unit 431 of the Web service call module generation unit 430 downloads the WSDL file from the Web service providing server 300, stores it in the memory, performs analysis, and the mapping template file generation unit 432 performs mapping based on the analysis result. A file template (mapping file as shown by 800 in FIG. 8 that has not been mapped yet) is generated. Further, the Web service call program generation unit 433 generates a Web service call program (Web service call module) by using a method disclosed in, for example, Japanese Patent Application Laid-Open No. 2011-059751, and stores it on the memory.

  The mapping file GUI (Graphical User Interface) display unit 441 of the mapping file editing unit 440 is a processing unit that displays the mapping file display screen 1000 shown in FIG. 10 and the like. The mapping file display processing unit 301 and the data model display unit 302 are displayed. Is provided. The description of 301 to 306 is omitted because it has been described above with reference to FIG. The data model definition receiving unit 442 acquires the data model definition from the repository definition unit 400 in response to a drag and drop operation of the data model definition to the mapping file display unit 1009 (specifically, the editing unit 1002 in FIG. 10). And keep it in memory. The mapping target item determination unit 305 and the mapping file generation unit 306 use the data model definition stored in the memory to match the input / output data item acquired from the WSDL on the mapping file and the data model item name. Determine and update.

  The web application 461 of the application server 200 includes a web service call program execution unit that receives and holds the web service call program compiled by the source code compilation unit 450 and executes the web service call program. The Web application 461 holds a Web application program generated by the Web application code generation unit 422 compiled by the source code compilation unit 450 and can execute the function. The above is the description of FIG.

  Next, with reference to FIG. 5, a flow of processing for generating a mapping file and a Web service calling program based on WSDL analysis according to the embodiment of the present invention will be described. FIG. 5 is a diagram for explaining an outline of processing of a known technique already disclosed in, for example, Japanese Patent Application Laid-Open No. 2011-059751.

  Each process in FIG. 5 is executed by the CPU 201 of the program development PC 100 using each function (part of functions of the program development application) of the Web service call module generation unit shown in FIG.

  First, in step S500, the WSDL analysis unit 431 of the program development PC 100 acquires the WSDL file 700 stored and published in the web service providing server 300 via the network (WAN 150 in FIG. 1), and the memory Expand on top.

  An example of a WSDL file is shown at 700 in FIG. A WSDL file (also referred to as WSDL) is a file that is made available so that a web service provided by the web service providing server 300 can be used by, for example, an application running on the application server 200. An XML file that contains information such as what methods the API exposes, what URI to access, what parameters to pass, what to return, what namespace to use, etc. is there. The WSDL file is downloaded and stored on the program development PC 100 when the Web service providing server 300 transmits the WSDL file to the program development PC 100 in accordance with a download request from the program development PC 100.

  In step S501, the WSDL analysis unit 431 analyzes the content of the read WSDL file 700. Specifically, the element ([service], [port], [binding], [portType], [message], [types], etc.) described in the WSDL file is disclosed for each element. Classify.

Specifically, in the case of the WSDL file 700 shown in FIG. 7, 702 in FIG. 7 is determined by interpreting it as an operation name, and 703 is set as an IN parameter (a parameter including input data items) necessary for invoking the Web service. Interpret and decide. Further, 701 is interpreted and determined as an OUT parameter (a parameter including an output data item output as a return value) when the Web service is called. These interpretations are described separately in the WSDL file 700, for example,
・ <Wsdl: operation name = “SLOC_JAVA_WSIO_getData”> Operation name indicated by <wsdl: input message = “axis2: SLOC_JAVA_WSIO_getDataRequest”... ..> Is performed by determining whether the character string of the output message indicated by <> matches the character string of the element name in <types>. ("JAVA" is a registered trademark)

  In step S502, the mapping file generation unit creates a mapping template file based on the information analyzed in step S501.

  The mapping file is, for example, used for causing a Web application operating on the application server 200 to use a Web service provided by the Web service providing server 300, and an input / output data item in the WSDL of the Web service and a data model handled by the Web application. In this embodiment, a mapping file (mapping template) in which mapping is not completed as indicated by 800 in FIG. 8 is generated at the time of step S502 in this embodiment. File). Specifically, it is a file in which DMCODE (805 in FIG. 8) indicating identification information of the data model to be mapped and DITEM (806 in FIG. 8) indicating the data item name of the data model definition are not input.

  As shown in FIG. 8, for example, name 702 (operation name) is expanded to name 802 (operation name) of the mapping file 800, IN parameter 703 is converted to IN parameter 803 (input), and OUT parameter 701 is converted to OUT parameter 801 (output). Each is inserted. Reference numeral 804 denotes an item name of an output data item described in the WSDL file 700, and the value of name 704 in FIG. 7 is inserted.

  In step S503, the Web service call program generation unit 433 sets the values of the IN parameter 703 and the OUT parameter 701 required when the Web service is called according to the definition of the mapping file 800 (FIG. 8). The data model definition stored in the memory (for example, the definition of the data item referenced by the function or screen of the Web application executed on the application server 200) is linked and interpreted, and between the Web service and the Web application The Web service and the Web application are translated so that they can be interpreted, and a Web service calling program for transmitting and relaying is generated.

  For example, the Web service calling program specifies an input data item on the mapping file associated with the argument data item received from the Web application, and passes the argument to the Web service as the value of the input data item. . Further, for example, the data of the return value data item (output data item) received from the Web service is used as the value of the data item on the data model definition associated with the output data item in the mapping file. Is a program that outputs and relays to The above is the description of FIG.

  Next, with reference to FIG. 6, the flow of the mapping file editing process in the embodiment of the present invention will be described.

  Each process of FIG. 6 is executed by the CPU 201 of the program development PC 100 using each function (part of functions of the program development application) of the mapping file editing unit 440 shown in FIG.

  In step S601, the GUI display unit 441 receives an instruction / instruction for opening a mapping file (shown in 800 in FIG. 8), and displays a GUI (mapping file display screen 1000) as shown in FIG. The file display processing unit 301 reads the instructed mapping file information on the memory and displays it on the mapping file display unit 1009 in FIG. 10 (corresponding to display control means).

  Further, the data model display unit 302 reads, for example, a data model definition definition file stored in the external memory of the program development PC 100 and displays it on the data list display unit 1008 in a selectable manner. The data list display unit 1008 is not limited to the data model definition, and other display areas can be selected by selecting data in a predetermined folder managed by the program development application by a user operation, or by copying and pasting or dragging and dropping. It is a display unit that displays a list so that data can be moved to.

  Among the information of the mapping file, name 802 (operation name) is displayed in a list so as to be selectable on the operation name display unit 1003. An operation is a unit of operation, and an operation name display part is an operation list display part. In the hierarchical structure display unit 1007, the element names in the operation tags (tags in the mapping file) selected in the operation name display unit 1003 are displayed in a hierarchical structure format so as to be selectable according to the description in the mapping file. (Corresponds to list display control means).

  Also, by accepting the pressing operation of the input tab 1005, the element of the element name selected in the hierarchical structure display unit 1007 (input of the IN parameter 803) among the elements in <input...> In the mapping file. Data item) is specified and displayed on the editing unit 1002. Also, by accepting the pressing operation of the output tab 1004, the element of the element name selected in the hierarchical structure display unit 1007 (in the OUT parameter 801) among the elements in the <output ...> tag in the mapping file. Output data item) is specified and displayed on the editing unit 1002. In the editing unit 1002 in FIG. 10, since the element name = “g” is selected in the hierarchical structure display unit 1007, various output is performed by narrowing down to the output element of 807 name = “g” in the mapping file 800. Displaying data items.

  In step S <b> 602, the movement operation reception unit 303 receives an operation of dragging and dropping the data model definition 1001 displayed on the data list display unit 1008 to the editing unit 1002. Further, the data model definition receiving unit 442 receives and acquires the dropped data model definition from the repository definition unit 400 by receiving the drag and drop operation. The drag and drop operation is an operation for instructing execution of a mapping process for associating a predetermined data item of the data model definition dropped in 1002 with a predetermined data item of WSDL input or output in the mapping file. . Here, the data model definition 1001 is a definition including the items / data indicated by reference numeral 901 in FIG. 9 and is actually a file stored on the external memory of the program development PC 100 as an XML file. . The data model definition can be displayed and edited on a screen such as 900 displayed on the display screen of the program development PC 100.

  In step S <b> 603, the data model determination unit 304 determines whether the data model definition is dropped on the editing unit 1002. That is, it is determined whether the moved file is a data model definition file. Specifically, the data model definition 1001 file (XML file) acquired by being dropped is expanded on a memory, and the internal structure (tag hierarchy, element name, etc.) of the expanded data model definition is read. If the information indicating the internal structure of the data model definition stored in advance in the external memory of the device matches the internal structure (tag hierarchy, element name, etc.) of the read file, the dropped file Judged as data model definition. If the dropped file is not a data model definition file, the process in FIG. 6 is terminated.

  If the dropped file is a data model definition file, then the processing of steps S604 to S605 is executed for the number of items of the data model definition 1001 (901) that has been dropped. That is, the processing of steps S604 to S605 is executed for all item codes 902 indicated by 901.

  In step S604, the mapping target item determination unit 305 acquires one value of the item code 902 of the data model definition 901, and determines whether the acquired value satisfies the mapping condition. The mapping condition is a determination condition / determination condition for determining and determining which input / output data item on the mapping file is associated with the item code 902 of the data model definition 901. For example, when the value of value is acquired from the item code 902 of the data model definition 901, it is determined whether the value 804 exists in the name 804 of the mapping file 800. That is, it is determined whether the name 804 of the mapping file 800 has a value that matches the item code 902 of the data model definition 901. When there is a matching value, it is determined that the value satisfies the mapping condition, and it is determined that the matching items are mapped (associated). If there is no data item that matches the condition, no mapping is performed for the data item.

  The data item name match determination in step S604 is a complete match of character strings, but the difference between uppercase and lowercase letters is ignored. Also, delimiters such as underscores are ignored. Therefore, for example, ITEM_01 and ITEM01 determine that the values match, and determine / determine that they are mapping targets.

  When it is determined that the data is to be mapped and the data item to be mapped is determined, the process proceeds to step S605. In step S605, the mapping file generation unit 306 performs mapping file update processing according to the determination, and displays the mapping result of the mapped item as indicated by 1011 in FIG. For example, if the value determined to be the mapping target in step S604 is “value”, the DMCODE 805 of the data model definition 1001 (= 901 in FIG. 9) subjected to the drop operation is added to the DMCODE 805 of the mapping file 800 shown in FIG. The value “g” is inserted according to the value, and the value “value” is inserted and updated (stored) according to the value DTIME of the data model definition 901 subjected to the drop operation in the DMIT 806. That is, mapping is performed between the data item of the data model definition and the data item published in the web service WSDL.

  Here, mapping is performed for the item currently displayed in the editing unit 1002. That is, other operations not selected in the operation name display unit 1003 on the mapping file displayed in the mapping file display unit 1009 and other operations not selected in the hierarchical structure display unit 1007 are selected. In the first place, the data item name (DMITTEM) of the dropped data model definition and the WSDL data item name (name 804) in the mapping file are not matched and are not mapped. Therefore, according to FIG. 10, DMCODE 805 and DTIMEM 806 corresponding to the output data item (name 804) of “g” selected in 1007 in the mapping file 800 are updated.

  An example of the mapping file after mapping is shown at 810 in FIG. An example of the display of the mapping result is shown at 1011 in the mapping file display screen 1010 after mapping in FIG. The mapping file after mapping is stored in the repository definition unit 400 in the external memory of the program development PC 100 by the mapping file generation unit 306.

  As a result, the WSDL file and the data model definition are associated (that is, the input / output data item of the Web service indicated by the WSDL and the data item of the data model definition on the client application side are associated). Therefore, for example, the data item value of the data model associated with the output data item of the OUT parameter in the mapping file is the data in the output data item described as the OUT parameter in the return value from the Web service. Can be output from the Web service calling program to the Web application program. For example, the value of the data item (data item defined by the data model definition) is displayed on the Web application screen provided by the Web application. The value of the output data item (for example, name 804) corresponding to the data item among the OUT parameters in the return value from the Web service can be displayed on the display unit.

  In FIG. 11, for example, when the search button is pressed on the Web application screen 1100 (the screen generated by the application server 200 to transmit screen information to the PC 101 and displayed on the PC 101), the value of DITEM = Value is set. A state in which a request acquired from the database of the Web service providing apparatus 300 is transmitted to the Web service, a return value as indicated by 1110 is received from the Web service, and the Web application screen 1100 is displayed in the state of 1120 and displayed. Show. In FIG. 11, the search key character string is not included in the request, and all values in the database corresponding to the iteration, language, type, and number of steps are requested.

  Actually, the Web service calling program specifies the data item name of the data model included in the request from the Web application with reference to the mapping file, and the input data for the Web service associated with the data item name The item name (name 804) is specified, and a search request for the value of name 804 is transmitted to the Web service. For example, a value value request is replaced with a value value request and transmitted. The Web service receives the request, acquires the value of name 804 (for example, the value of value) in the database, and returns it as a return value 1110. The Web service calling program that has received the return value acquires the output data item name indicated by the return value, specifies the corresponding data model definition data item by referring to the mapping file, and specifies the return value value. The data item value is output to the Web application. For example, the value value in the return value is replaced with the value value and output to the Web application. The Web application inserts the value of the value received from the Web service calling program into the 1101 defined as a box for displaying the value by inserting the value in the Web application, and updates the screen from 1100 to 1120. And displaying.

  If there is a data item to be mapped, the mapping file is not updated. If the processing of steps S604 to S605 has been executed for the number of items of the data model definition 1001 subjected to the drop operation, the processing of FIG. If the process of steps S604 to S605 has not been executed for the number of items of the data model definition 901 (1001 in FIG. 10) that has been dropped, the process returns to step S603, and the data model definition 901 has not been processed. The data items are acquired, and the processes of steps S604 and S605 are executed.

  Note that the mapping file display processing unit 301 inserts the mapped DMCODE and DTIME values (mapping target item names in the dropped data model definition) into the mapped name lines, as indicated by reference numeral 810 in FIG. And display it as an update result.

  Further, the mapping file display processing unit 301 corresponds to an identification object 1012 for identifying the mapped item next to the mapped line in the edited and edited line, as indicated by 1010 in FIG. To display. This does not necessarily have to be an object, and may be, for example, a character that identifies a mapped item.

  Further, the mapping file display processing unit 301 displays an identification 1013 for identifying an operation including the mapped item in association with the operation. This does not necessarily have to be an object, for example it may be a character that identifies the operation that contains the mapped item. The above is the description of FIG.

  As described above, according to the first embodiment of the present invention, it is possible to easily map items related to a Web service.

  For example, the processing of FIG. 6 allows the mapping file to be updated and mapped by an intuitive operation such as drag and drop.

  <Second Embodiment>

  A second embodiment of the present invention will be described with reference to FIGS. Descriptions of processes, data, and screens common to the first embodiment are omitted.

  The second embodiment aims to provide a mechanism that facilitates the setting of mapping conditions and allows easy mapping of items related to Web services.

  For example, it is possible to facilitate the setting of the mapping condition and secure the freedom of the mapping work by reducing the trouble of manually opening and editing the setting screen (not shown) for the mapping condition. it can.

  The process in FIG. 12 is executed by the CPU 201 of the program development PC 100 when it is determined in step S603 in FIG. 6 that the dropped data is a data model definition.

  In step S1201, the data model determination unit 304 refers to setting information (not shown) stored in the external memory of the program development PC 100 so that the setting can be changed, and a data model mapping condition selection screen (shown in 1301 in FIG. 13). It is determined whether the display setting is set to ON. If it is OFF, the process in FIG. 12 is terminated, the process proceeds to step S604 in FIG. 6, and the processes in steps S604 to S605 are applied to all unprocessed items.

  If the display setting of the data model mapping condition selection screen (shown in 1301 of FIG. 13) is set to ON, the process proceeds to step S1202. In step S1202, the data model determination unit 304 displays the mapping condition selection screen 1301 of FIG. 13 on the display screen (corresponding to selection screen display control means).

  The mapping condition selection screen 1301 is a screen for reading a plurality of mapping conditions (matching determination conditions used in step S604 in FIG. 6) from the external memory and displaying them in a selectable manner. The conditions used for the matching determination in step S604 are displayed by the user. This is a screen for letting you select.

  In step S1203, when the data model determination unit 304 accepts an operation of selecting and determining a mapping condition (pressing the “OK” button), the data model determination unit 304 determines the condition selected at the time when the “OK” button was westernized in step S604. Are determined as mapping conditions used for matching determination, and are stored in the memory as the conditions employed in step S604. Thereafter, the process proceeds to step S604. In step S604, the mapping target item determination unit 305 uses the mapping conditions (conditions determined to match) determined in step S1203 and stored in the memory to obtain the data model definition acquired when executing step S604. It is determined whether there is a value of name 804 that matches the item code 902 of 901. According to 1301 in FIG. 13, based on the fuzzy matching condition (for example, a condition for determining that the character strings to be matched are matched even if the target character strings to be matched are partially matched) in step S <b> 604. Perform a match determination.

  As described above, according to the second embodiment of the present invention, it is possible to provide a mechanism that facilitates the setting of mapping conditions and enables easy mapping of items related to Web services.

  For example, by selecting the mapping condition to display a screen in response to drag and drop of the data model definition, the user has to manually open a setting screen (not shown) and edit the mapping condition. It is possible to reduce, facilitate the setting of mapping conditions, and secure the degree of freedom of mapping work.

  <Third Embodiment>

  Next, a third embodiment of the present invention will be described with reference to FIGS. Descriptions of processes, data, and screens that are common to the first and second embodiments are omitted.

  In the third embodiment, a corresponding item is specified using dictionary data, displayed on a display screen as a candidate for mapping, and allowed to be selected by a user, thereby providing a mechanism that facilitates mapping of items related to a Web service. For the purpose.

  By presenting candidates and allowing the user to select, the possibility that mapping unintended by the user is automatically performed is reduced, and mapping of items that do not completely match can be easily performed. Time and effort can be reduced.

  First, FIG. 14 will be described. FIG. 14 shows the flow of dictionary data registration processing.

  Assume that a screen such as 1010 in FIG. 10 is displayed at the time of step S1401. In step S1401, the CPU 201 of the program development PC 100 accepts a new input or input change operation of a data model code or data model item, holds the value input on the memory, and stores the value input to the target cell 1002 indicate.

  In step S1402, the input value is stored in the mapping file, and it is determined whether an operation for updating the mapping file has been accepted. For example, when a mapping file saving operation by pressing a “save” button (not shown) on 1010 or a tab switching operation by pressing the input tab 1005 or the output tab 1004 is received, the input value is stored in the mapping file. It is determined that an operation for saving and updating the mapping file has been received.

  If a save / update operation is accepted, in step S1403, whether the values of all input / edited cells are the same as the property name (name 804) corresponding to the input / edited cell (in the same row). judge. If they are the same, it is not necessary to create a dictionary.

  If there is a cell having a different value, the value in the cell is acquired and registered in the dictionary data in association with the value of the corresponding name 804 (step S1405). If the dictionary data has not been generated, the dictionary data is generated and registered on the external memory of the program development PC 100 (step S1404). An example of dictionary data is shown in FIG. 15 (corresponding to dictionary data storage means).

  The dictionary data in FIG. 15 is an example of dictionary data generated when the mapping file is updated by inputting category in the cell of the data model item code corresponding to property name = type, which is 1010 in FIG. . The above is the description of FIG.

  Next, the flow of the mapping file editing process using dictionary data will be described with reference to FIG.

  The process in FIG. 16 is executed by the CPU 201 of the program development PC 100 when it is determined in step S603 in FIG. 6 that the dropped data is a data model definition.

  In step S1601, the mapping file generation unit 306 acquires the dictionary data in FIG. 15, and executes the processing in steps S1602 to S1606 for the number of property names that have been dropped.

  In step S1602, the mapping file generation unit 306 acquires one value of name 804 (property name) displayed in the dropped editing unit 1002, and the property name of the DMITEM or dictionary of the data model that matches the value is obtained. Determine if there is. If there is a matching value, the matching value is stored in the memory, and the process proceeds to step S1603.

  In step S1603, the mapping file generation unit 306 determines whether the property name displayed in the editing unit 1002 acquired in step S1602 matches both the DITEM of the dropped data model and the property name of the dictionary data. On the other hand, if there is only one combination, the process proceeds to step S1604, and the matched values are mapped (same as the process in step S605). On the other hand, if it matches both the DMITEM of the dropped data model and the property name of the dictionary data, the process proceeds to step S1605.

  In step S <b> 1605, the mapping file generation unit 306 performs a mapping process in which DMITE of the dropped data model among the matched values is associated with the property name 1002. In step S1606, the data model item code corresponding to the property name of the dictionary data that matches the property name is specified and acquired, and stored in the memory in association with the property name. After applying the processing of steps S1602 to S1606 to all the property names of 1002, the processing proceeds to step S1607.

  In step S1607, the mapping file generation unit 306 identifies and displays the display cell of the data model item code corresponding to the property name that has been matched in step S1603, as indicated by 1701 in FIG.

  When a click operation (designation) of the cell is accepted in step S1608, a selection screen 1711 as shown in FIG. 17 is displayed in step S1609. The selection screen 1711 is specified by the dictionary data as corresponding to the property name being displayed in 1002 (specified as being stored in association with the property name being displayed in 1002 on the dictionary data). This screen displays a code (DMITEM) as a selection candidate (corresponding to the candidate display control means) and accepts the selection to insert the selected value into a cell (1701 in FIG. 17) corresponding to the selection screen 1711. .

  In step S1610, the mapping file generation unit 306 determines whether the selection operation of the data model item code (“category” in FIG. 17) specified by the dictionary data is received on the selection screen 1711 and selects “category”. When the operation is accepted, property name = type and DTIMEM = category are associated with each other on the mapping file and updated (step S1611). If the “category” selection operation is not accepted, the process ends.

  As described above, according to the third embodiment of the present invention, a corresponding item is specified using dictionary data, displayed on a display screen as a candidate for mapping, and selected by a user to be applied to a Web service. A mechanism that facilitates mapping of items can be provided.

  For example, by presenting candidates and allowing the user to select, it is possible to reduce the possibility that mapping that is not intended by the user is automatically performed, and to easily perform mapping between items that do not completely match, User trouble can be reduced.

  In the description of the third embodiment described above, first, in step S1605, the DMITEM value of the dropped data model is mapped in preference to the data model item code value of the dictionary. Neither value is mapped and stored in the memory in association with the matched 1002 property name. In step S1607, a screen such as the selection screen 1801 in 1800 of FIG. Any one of the above may be selected and mapped by the user. By doing so, the mapping of property names that match a plurality of values can be assured of an instruction from the user and appropriate mapping can be easily performed.

  <Fourth Embodiment>

  Conventionally, when it is necessary to call all CRUDs for the same table, mapping to the same data model has to be performed a plurality of times. For example, if there are two or more operations that use the same data model (such as a data search operation for displaying a data list screen and a data search operation for displaying a detailed screen of data selected from the list), the data model to handle Despite being the same, under each operation tag in the mapping file, it was necessary to perform mapping by editing text, which was a heavy workload.

  In the first embodiment, since mapping is possible by the drag and drop operation of the data model definition, it is necessary to manually edit the text of the mapping file or to input / edit the same information multiple times. You can reduce the mental load and fatigue caused by not having to repeat the same work, but drag and drop operations must be performed multiple times.

  In the fourth embodiment, an object is to provide a mechanism capable of easily mapping items related to a Web service to items in a plurality of mapping files.

  Descriptions of processes, data, and screens common to the first to third embodiments are omitted.

  After completing all the processing in step S605, the mapping file generation unit 306 identifies an operation having the same property name list as the property name (name 804) list of the editing unit 1002 to which the data model has been dropped. The mapping file is updated by associating each property name (name 804) of the identified operation with the value of DMITE that is the same as that of DITEM associated in S605.

  In other words, a plurality of operations can be mapped by one drag and drop operation of the data model.

  As described above, according to the fourth embodiment of the present invention, it is possible to provide a mechanism that can easily map items related to a Web service to items in a plurality of mapping files. .

  As described above, it is possible to provide a mechanism that can easily map items related to a Web service.
