Description

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

A web service is known as a mechanism for calling an application running on a server from an application of a client device and using the application. The Web service is an application of an Internet-related technology such as HTTP (HyperText Transport Protocol) to send and receive a message using a service in the form of XML (Extensible Markup Language) called SOAP (Simple Object Access Protocol). Is.

In the Web service client (client application) that calls the Web service, what method is published by the published WSDL (Web Services Description Language/Web service), and what is the URI to be accessed? , A proxy class file generated based on an XML file that describes information such as what parameters to pass, what return value, what namespace to use, etc. is often used. The proxy class is a Web service calling program that plays a role of allowing an application running on a server in a client to be accessed via the Web in the same manner as accessing a local library.

When the specification of the Web service is changed, the WSDL published to use the application (server application) running on the server is also changed. Therefore, the proxy class generated from WSDL is changed and used in the client application. Patent Document 1 describes a method of detecting a change in the WSDL and automatically changing the proxy class in response to the change in the Web service. However, according to the technique of the cited document 1, the client application program that calls the proxy class cannot be dynamically changed, so that the user needs to modify the client application program itself. In order to reduce this trouble, in Patent Document 2, a mapping file template is generated from WSDL, and mapping by manual input by the user (data items of data model definition and INPUT, OUTPUT of Web service described in WSDL) is performed. The technology that enables the user to enjoy the web service without changing the client application program is disclosed.

An example of an embodiment of the present invention will be described below 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 enables easy mapping of items related to Web services.

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

First, with reference to FIG. 1, an example of a configuration of an information processing system according to an embodiment of the present invention will be described.

In the information processing system of the present invention, as shown in FIG. 1, various devices such as a program development PC 100, a PC 101, an application server 200, and a web service providing server 300 can communicate with each other via a network such as WAN 150 (wide area network). Is configured and connected to.

The program development PC 100 causes a program development application (application generation unit 410 in FIG. 4) on the program development PC to operate on its own machine 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 a WSDL (WSDL) for using the web service in an external device/external application (eg, an application running on the application server 200/a client application for the web service). WEB service description language file) is open to the public.

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 method described in JP2011-059751A to describe the mapping file and the proxy class (Web service). Calling program) is generated. In addition, the mapping file is updated using a data model (also referred to as a data model definition) stored in the device itself according to a user operation. Then, by sending the mapping file after mapping and the Web service calling program to the application server, the Web service can be used (deployed) by an application (Web application) running on the application server.

The mapping file in this embodiment is a correspondence file that associates the data model on the Web application side (client application side) with the input/output data items of the Web service. The data model used by the database managed by the web application itself and created for the web application is exactly the same as the schema of the database. However, in the mechanism of using the Web service, the data model used by the Web application does not always match the input/output data item of the Web service. This is because, for example, the company designing/managing the Web application and the Web service is different, or the design concept/data management rule is 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 (the input/output data item disclosed by WSDL). This is called mapping.

The application server 200 includes a Web application that executes a process/function according to an operation instruction from an external device such as the PC 101. Also, for example, the data model of the argument is determined and input as an input value (input parameter) in the Web service calling program by referring to the mapping file. The Web service calling program converts the input value into a SOAP message and sends the SOAP message to the Web service program of the Web service providing server 300, and the data model of the returned value obtained as a response is a Web application mapped in the mapping file. It is applied to the data model handled by and output to the Web application. In other words, even if the specification of the Web service (WSDL specification) is changed, it is possible to use the Web service by changing the specification of the Web service by changing the mapping file without changing the Web application program. Is configured. The above is the description of FIG. 1.

Next, with reference to FIG. 2, an example of a hardware configuration of various devices in the embodiment of the present invention will be described.

In FIG. 2, reference numeral 201 denotes a CPU, which centrally 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 control program of the CPU 201 such as a BIOS (Basic Input/Output System), an operating system program (hereinafter, OS), and a function executed by each server or each PC. Various programs described later are stored.

A RAM 203 functions as a main memory and a work area of the CPU 201. The CPU 201 loads various programs necessary for executing the processing from the ROM 202 or the external memory 211 into the RAM 203, and executes the loaded programs to realize various operations.

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 the display 210 (for example, a CRT display). The display device is not limited to the CRT display and may be another display device such as a liquid crystal display. These are used by the user as needed.

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

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

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

Various programs to be described later for implementing the present invention are recorded in the external memory 211, and are executed by the CPU 201 by being loaded into the RAM 203 as necessary. Furthermore, the definition file and various information tables used when the above program is executed 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 the 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 the process of the flowchart described later using each function of the program development application.

The mapping file display processing unit 301 is a processing unit that displays the information of the mapping file on the mapping file display unit 1009 on the mapping file display screen as shown in FIG. 10, for example, in response to a user operation. 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 receiving unit 303 receives a data move operation such as a drag and drop operation on 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 the data subjected to the move operation (drag and drop operation) is the data model definition. The mapping target item determination unit 305, when the moved data is a data model definition, the input/output data item (input data item (INPUT) or the input data item (INPUT) of the mapping file displayed in the editing unit 1002 of the moving destination). Matching of the item name (character string of identification information) of the output data item (OUTPUT) and the predetermined data item name in the data model definition that has been moved is performed, and items with matching item names are associated with each other. , That is, a processing unit that decides to perform mapping. The mapping file generation unit 306 generates, on the external memory, a mapping file that maps the items determined to be associated with each other according to the determination made by the mapping target item determination unit 305. For example, the information of the mapping file stored in the external memory and displayed at the destination (editing unit 1002) where the move operation was performed is read out into the memory, and the mapping target item determination unit 305 is read in the mapping file. By performing mapping between the items determined by, and overwriting/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 configurations of various devices 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. The description of 301 to 306 described above in the description of FIG. 3 is omitted.

The program development PC 100 has a repository definition unit 400, an application generation unit 410, a Web application base 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 the developer through the program development application, created, and stored in the external memory of the program development PC 100.

That is, the repository definition unit 400 is input definition information for Web application that defines an item input as an argument for executing the program, and output definition information for Web application that defines an item to be output as a processing result of executing the program. Is an example of a means for managing and as Web application input/output definition information. The web application referred to here is 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, etc. from the repository definition unit 400. The Web application code generation unit 422 uses the code generation rule stored in the external memory 211 and the content analyzed by the repository definition analysis unit 421 via the source code compilation unit 450 to execute 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, analyzes it, and the mapping template file generation unit 432 performs mapping based on the analysis result. Generate a file template (mapping file not completed yet, as shown at 800 in FIG. 8). Further, the Web service calling program generation unit 433 generates a Web service calling program (Web service calling module) using the method disclosed in Japanese Patent Laid-Open No. 2011-059751 and stores it in the memory.

A 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 or the like, and includes a mapping file display processing unit 301 and a data model display unit 302. Equipped with. The description of 301 to 306 will be omitted because it has been described in the description of FIG. The data model definition receiving unit 442 acquires the data model definition from the repository defining unit 400 in response to the 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 hold it in memory. The mapping target item determination unit 305 and the mapping file generation unit 306 use the data model definition held in the memory to match the input/output data item acquired from the WSDL on the mapping file with the item name of the data model. Judge and update.

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

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

Each processing of FIG. 5 is executed by the CPU 201 of the program development PC 100 using each function of the Web service call module generation unit shown in FIG. 4 (a part of the function of the program development application).

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 stores it in the memory. Expand to the top.

An example of the WSDL file is shown at 700 in FIG. The WSDL file (also referred to as “WSDL”) is a file that is published to make the Web service provided by the Web service providing server 300 available to, for example, an application running on the application server 200. An XML file that describes information such as what methods the API exposes, what URI to access, what parameters to pass, what return value, what namespace to use, etc. is there. The WSDL file is downloaded and stored in the program development PC 100 by being transmitted to the program development PC 100 by the Web service providing server 300 in accordance with the download request from the program development PC 100.

Next, in step S501, the WSDL analysis unit 431 analyzes the contents of the read WSDL file 700. Specifically, the elements (publicized) described in the WSDL file ([service], [port], [binding], [portType], [message], [types], etc.) are specified for each element. Classify.

Specifically, in the case of the WSDL file 700 shown in FIG. 7, 702 referred to in FIG. 7 is determined by interpreting it as an operation name, and 703 is used as an IN parameter (parameter including an input data item) required to call the Web service. Interpret and decide. Further, 701 is interpreted and determined as an OUT parameter (parameter including an output data item output as a return value) when the Web service is called. These interpretations are separately described in the WSDL file 700, for example,
· <Wsdl: operation name = "SLOC_JAVA_WSIO_getData"> operation name, shown in the <wsdl: input message = "axis2: SLOC_JAVA_WSIO_getDataRequest"···> input message is shown in the <wsdl: output message = "axis2: SLOC_JAVA_WSIO_getDataResponse" · ..> The character string of the output message shown in> and the character string of the element name in <types> are determined to match. ("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 used, for example, for causing a Web application running on the application server 200 to use the 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. 8 is a file that is associated (mapped) with the data item of No. 1. However, in the present embodiment, what is generated at the time of step S502 is a mapping file (mapping template shown in 800 of FIG. 8) for which mapping has not been completed. File). Specifically, it is a file in which DMCODE (805 in FIG. 8) indicating the 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, the name 702 (operation name) is expanded into the name 802 (operation name) of the mapping file 800, the IN parameter 703 becomes the IN parameter 803 (input), and the OUT parameter 701 becomes the OUT parameter 801 (output). Each is inserted. Reference numeral 804 indicates the item name of the output data item described in the WSDL file 700, and the value of the 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 OUT parameter 701 required when calling the Web service to the outside of the program development PC 100 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 referred to by the function or screen of the Web application executed by the application server 200) is interpreted and linked, and the Web service and the Web application are connected to each other. , A Web service and a Web application are translated so that they can be interpreted, and a Web service call program for transmitting and relaying is generated.

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

Next, with reference to FIG. 6, a flow of the editing process of the mapping file 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 of the mapping file editing unit 440 shown in FIG. 4 (a part of the function of the program development application).

In step S601, the GUI display unit 441 receives an instruction/instruction for opening a mapping file (illustrated at 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 into 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 definition file of the data model definition stored in the external memory of the program development PC 100 and displays it in 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 data in a predetermined folder managed by the program development application can be selected by a user operation or can be copied and pasted or dragged and dropped to another display area. It is a display unit that displays a list so that data can be moved to.

Among the information of the mapping file, the name 802 (operation name) is displayed in the operation name display unit 1003 in a selectable list. An operation is a unit of operation, and the operation name display section is an operation list display section. In the hierarchical structure display unit 1007, the element name in the tag of the operation selected in the operation name display unit 1003 (tag in the mapping file) is displayed in a selectable hierarchical structure according to the description in the mapping file. Yes (corresponds to the list display control means).

Further, by accepting the pressing operation of the input tab 1005, among the elements in <input...> In the mapping file, the element having the element name selected in the hierarchical structure display unit 1007 (input of the IN parameter 803) The data item) is specified and displayed on the editing unit 1002. Further, by accepting the pressing operation of the output tab 1004, among the elements in the <output...> tag in the mapping file, the element of the element name selected in the hierarchical structure display unit 1007 (OUT parameter 801 The output data item) is specified and displayed on the editing unit 1002. In the editing unit 1002 of FIG. 10, since the element name=“g” is selected in the hierarchical structure display unit 1007, various outputs are narrowed down to the output elements of the name=“g” of 807 in the mapping file 800. You are displaying a data item.

In step S602, the move operation receiving unit 303 receives an operation of dragging and dropping the data model definition 1001 displayed in the data list display unit 1008 to the editing unit 1002. In addition, the data model definition receiving unit 442 receives and acquires the dropped data model definition from the repository defining 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 input or output of WSDL in the mapping file. .. Here, the data model definition of 1001 is a definition including the items/data shown in 901 of FIG. 9, and is actually a file stored in the external memory of the program development PC 100 as an XML file. .. The data model definition can be displayed/edited on a screen such as 900 displayed on the display screen of the program development PC 100.

In step S603, 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 file (XML file) of the data model definition 1001 acquired by being dropped is expanded on the memory, and the file 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 itself matches the internal structure of the read file (tag hierarchy, element name, etc.), the dropped file is Judge as data model definition. If the dropped file is not the data model definition file, the processing of FIG. 6 ends.

When the dropped file is the data model definition file, the processes of steps S604 to S605 are executed thereafter for the number of items of the dropped data model definition 1001 (901). That is, the processes of steps S604 to S605 are executed for all the item codes 902 shown in 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 value is acquired from the item code 902 of the data model definition 901, it is determined whether the value 804 of the mapping file 800 has a value value. 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 decided to map (correlate) the matching items. If there is no data item that meets the conditions, no mapping is performed for that data item.

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

If it is determined that the data item is the mapping target and the data item that is the mapping target is determined, the process proceeds to step S605. In step S605, the mapping file generation unit 306 updates the mapping file in accordance with the determination, and displays the mapping result of the mapped item as indicated by 1011 in FIG. For example, when the value determined to be the mapping target in step S604 is “value”, the DMCODE 805 of the mapping file 800 illustrated in FIG. 8 is added to the DMCODE of the data model definition 1001 (=901 of FIG. 9) that has been subjected to the drop operation. According to the value, the value of “g” is inserted, and the value of “value” is inserted and updated (stored) in the DMITEM 806 according to the value of DMITEM of the dropped data model definition 901. That is, the data item of the data model definition and the data item published in the WSDL of the Web service are mapped.

Here, mapping is performed for the item displayed in the editing unit 1002. That is, on the mapping file displayed on the mapping file display unit 1009, other operations that are not selected on the operation name display unit 1003, or among the selected operations that are not selected on the hierarchical structure display unit 1007. Regarding the data item in the element of (1), the data item name of the dropped data model definition (DITEM) is not matched with the data item name (name 804) of the WSDL on the mapping file, and the data item is not mapped. Therefore, according to FIG. 10, DMCODE 805 and DMITEM 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 is associated with the data model definition (that is, the input/output data item of the Web service indicated by the WSDL is associated with the data item of the data model definition on the client application side). Therefore, for example, the value of the data item of the data model in which the data in the output data item described as the OUT parameter in the return value from the Web service is associated with the output data item of the OUT parameter in the mapping file. As a result, it is possible to 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. It becomes possible to display 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 on the display unit.

In FIG. 11, for example, by pressing the search button on the Web application screen 1100 (the screen generated by the application server 200 and transmitting the screen information to the PC 101 and displayed on the PC 101), the value of DTIME=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 shown in 1110 is received from the Web service, and the Web application screen 1100 is displayed again in the state of 1120 is displayed. Showing. In FIG. 11, by not including the character string of the search key in the request, all values in the database corresponding to the iteration, language, type, and number of steps are requested.

Actually, the Web service calling program identifies the data item name of the data model included in the request from the Web application by referring 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 the name 804 is sent to the Web service. For example, the request for the value of Value is replaced with the request for the value of value and transmitted. The Web service accepts 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 call program that has received the return value acquires the output data item name indicated by the return value, identifies the corresponding data model definition data item by referring to the mapping file, and determines the return value value. It is output to the Web application as the value of the selected data item. For example, the value of value in the return value is replaced as the value of Value and is output to the Web application. The Web application inserts the Value value received from the Web service calling program into 1101 which is defined as a box in which the Value value is inserted and displayed in the Web application, and the screen is updated from 1100 to 1120. And then display.

If there is a data item to be mapped, the mapping file is not updated, and if the processes of steps S604 to S605 have been executed for the number of items of the data model definition 1001 that has undergone the drop operation, the process of FIG. 6 ends. If the processes of steps S604 to S605 have not been executed for the number of items of the data model definition 901 (1001 in FIG. 10) that has been subjected to the drop operation, the process is returned to step S603, and the unprocessed data model definition 901 is not processed. The data item of is acquired and the processes of steps S604 and S605 are executed.

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

In addition, the mapping file display processing unit 301 associates an identification object 1012 for identifying the mapped item next to the mapped and edited line, as indicated by 1010 in FIG. 10. Attach and display. This does not necessarily have to be an object, but may be a character that identifies the mapped item, for example.

Further, the mapping file display processing unit 301 displays the identification 1013 for identifying the operation including the mapped item in association with the operation. This does not necessarily have to be an object, but may be, for example, a character that identifies the operation that contains the mapped item. The above is the description of FIG. 6.

As described above, according to the first embodiment of the present invention, it is possible to easily perform mapping of items related to Web services.

For example, by the processing of FIG. 6, the mapping file can be updated and the mapping can be executed 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 processing, data, and screens common to the first embodiment will be omitted.

The second embodiment has an object to provide a mechanism that facilitates setting of mapping conditions and mapping of items related to a Web service.

For example, it is possible to easily set the mapping condition and to secure the degree of freedom of the mapping work by reducing the trouble of editing the setting condition of the mapping condition by manually operating the setting screen (not shown) by the user. it can.

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

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

When the display setting of the data model mapping condition selection screen (illustrated 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 (conditions for matching determination used in step S604 of FIG. 6) from an external memory and displaying them in a selectable manner. The conditions used for matching determination in step S604 are set by the user. This is a screen to let the user select.

In step S1203, when the data model determination unit 304 accepts the operation of selecting and deciding the mapping condition (pressing the “OK” button), the data model determining unit 304 determines the condition selected at the time when the “OK” button was Europeanized, in step S604. In step S604, the mapping condition is determined as the mapping condition to be used for the matching determination, and is stored in the memory as the condition used in step S604. Then, the process proceeds to step S604. In step S604, the mapping target item determination unit 305 uses the mapping conditions (conditions for determining matching) determined in step S1203 and stored in the memory to acquire the data model definition obtained in execution of step S604. It is determined whether or not 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 match condition (for example, the condition for determining that the character strings match even if the target character strings for the match determination are only partially matched) of step S604. Matches are determined.

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

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

<Third Embodiment>

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

The third embodiment provides a mechanism for facilitating the mapping of items related to Web services by identifying the corresponding items using the dictionary data, displaying them on the display screen as candidates for mapping, and allowing the user to select them. The purpose is to

By presenting candidates and letting the user select, it is possible to reduce the possibility that automatic mapping not intended by the user will be performed, and to easily perform mapping between items that do not completely match. It can reduce the labor.

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

At the time of step S1401, it is assumed that a screen like 1010 in FIG. 10 is displayed. In step S1401, the CPU 201 of the program development PC 100 accepts a new input of a data model code or a data model item and an operation of changing an input, holds the value input in the memory, and stores the value input in the target cell 1002. indicate.

In step S1402, the input values are saved in the mapping file, and it is determined whether an operation to update the mapping file has been accepted. For example, when the saving operation of the mapping file by pressing the “Save” button (not shown) on 1010 and the switching operation of the tabs by pressing the input tab 1005 and the output tab 1004 are accepted, the input value is stored in the mapping file. It is determined that the operation of saving and updating the mapping file has been accepted.

When the save/update operation is accepted, in step S1403, the values of all the cells that have been input/edited are the same as the property names (name 804) corresponding to the cells that have been input/edited (in the same row). judge. If they are the same, it is not necessary to bother to create a dictionary, so the processing ends.

When 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 in the external memory of the program development PC 100 and then registered (step S1404). An example of the dictionary data is shown in FIG. 15 (corresponding to dictionary data storage means).

The dictionary data of FIG. 15 is an example of the dictionary data generated when the mapping file is updated by inputting “category” in the cell of the data model item code corresponding to the property name=type in 1010 of FIG. .. The above is the description of FIG. 14.

Next, with reference to FIG. 16, a flow of a mapping file editing process using dictionary data will be described.

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

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

In step S1602, the mapping file generation unit 306 acquires one value of the name 804 (property name) displayed in the dropped editing unit 1002, and the DMITEM or dictionary property name of the data model that matches the value is acquired. 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 DMITEM of the dropped data model and the property name of the dictionary data. If there is one match, and there is only one combination, the process moves to step S1604, and the matched values are mapped (the same as the process of step S605). On the other hand, if both the DMITEM of the dropped data model and the property name of the dictionary data match, the process moves to step S1605.

In step S1605, the mapping file generation unit 306 performs a mapping process of associating the DMITEM of the dropped data model among the matched values with the property name 1002. Then, in step S1606, the data model item code corresponding to the property name of the dictionary data that matches the property name is identified and acquired, and is stored in the memory in association with the property name. After applying the processes of steps S1602 to S1606 to all the property names 1002, the process 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 plural property names that match in step S1603, as indicated by 1701 in FIG.

When the 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 identified by the dictionary data as being associated with the property name being displayed in 1002 (identified as being stored in association with the property name being displayed in 1002 on the dictionary data). It is a screen on which a code (DMITEM) is displayed as a selection candidate (corresponding to a candidate display control unit) and a selected value can be inserted into a cell (1701 in FIG. 17) corresponding to the selection screen 1711 by accepting the selection. ..

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

As described above, according to the third embodiment of the present invention, the corresponding item is identified using the dictionary data, displayed on the display screen as a candidate for mapping, and the user is allowed to select the item. A mechanism that facilitates item mapping can be provided.

For example, by presenting candidates and prompting the user to select, it is possible to reduce the possibility that automatic mapping that is not intended by the user will be performed, and it is possible to easily perform mapping between items that do not completely match, The user's time and effort can be reduced.

In addition, in the above description of the third embodiment, in step S1605, the value of the DMITEM of the dropped data model is first mapped to the value of the data model item code of the dictionary, but, for example, Neither value is mapped and stored in the memory in association with the matched property name of 1002, and in step S1607, a screen such as the selection screen 1801 in 1800 of FIG. 18 is displayed to display the matched value. Any one of the above may be selected and mapped by the user. By doing so, regarding the mapping of the property name that matches a plurality of values, the user can be surely instructed and the appropriate mapping can be easily performed.

<Fourth Embodiment>

Conventionally, when it is necessary to call all CRUDs for the same table, it is necessary to perform mapping to the same data model multiple times. For example, when 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 be handled Despite the same, the work load was high because it was necessary to perform text editing and mapping under each operation tag in the mapping file.

In the first embodiment, since the mapping can be performed by the drag and drop operation of the data model definition, it is necessary to manually edit the text of the mapping file, and the same information must be input/edited multiple times. You can reduce mental stress and fatigue caused by not having to do it (you have to repeat the same work), but you need to perform drag and drop operations multiple times.

The fourth embodiment has an object to provide a mechanism capable of easily performing mapping of items related to Web services to items in a plurality of mapping files.

Description of processes, data, and screens common to the first to third embodiments will be omitted.

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

That is, the mapping related to a plurality of operations can be performed 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 enables easy mapping of items related to Web services to items in a plurality of mapping files. ..
