  In the AP providing apparatus 300, the AP use accepting unit 331, the AP execution unit 332, and the data operation unit 333 are realized by a program that causes the arithmetic device 113 of the AP providing apparatus 300 to perform processing.

  Next, the project management process in this embodiment is demonstrated based on FIG.

  FIG. 15 is a diagram illustrating a process flow of the project management process.

  First, a start phase (from step S1 to step S7) for starting an application service in the project management process will be described.

  The project management process is started when the browser unit 133 of the service user terminal 100 receives a start instruction from the user via the input information receiving unit 131.

  First, the browser unit 133 of the service user terminal 100 requests an initial page from the data storage device 200 (step S1).

  Specifically, the browser unit 133 transmits an HTTP (Hypertext Transfer Protocol) request to a URL (Uniform Resource Locator) specified in the browser unit 133. Note that the URL includes information such as an identifier for identifying an application service that the user wants to use.

  Next, the data storage device 200 generates an initial page (step S2).

  Specifically, the initial screen generation unit 231 generates an HTML page including the URI of the AP providing apparatus 300 corresponding to the identifier for identifying the application service included in the URL transmitted in step S1 as an initial page.

  Next, the data storage device 200 transmits the generated initial page to the service user terminal 100 (step S3).

  Specifically, the initial screen generation unit 231 transmits the HTML generated in step S2 to the service user terminal 100 as an HTTP response.

  Next, the service user terminal 100 executes the initial page transmitted in step S3 (step S4).

  Specifically, the browser unit 133 acquires HTML from the HTTP response transmitted in step S3, configures a screen based on the HTML, and displays the screen via the output information generation unit 132. At that time, the browser unit 133 acquires the URI of the AP providing apparatus 300 included in the HTML page.

  Next, the service user terminal 100 transmits an application program start request to the AP providing apparatus 300 (step S5).

  Specifically, the browser unit 133 transmits an HTTP request to the URI of the AP providing apparatus 300 acquired in step S4.

  Next, the AP providing apparatus 300 distributes the requested application program to the service user terminal 100 (step S6).

  Specifically, the AP use accepting unit 331 includes an AP script (ticket) 160 and an AP script (project) 165 necessary for realizing an application service corresponding to the URI included in the HTTP request transmitted in step S5. And the script library 180, the DSDA module 190, and the APDA module 196 are identified. Then, the AP use accepting unit 331 delivers an application program including each identified module to the service user terminal 100.

  Next, the service user terminal 100 starts executing the application program distributed in step S6 (step S7).

  This is the start phase for starting the application service in the project management process.

  Next, the execution phase in the project management process will be described.

  When the service user terminal 100 receives an instruction for processing to be executed on the AP providing apparatus 300 side during execution of the application program, the service user terminal 100 transmits a function execution request to the AP providing apparatus 300 (step S8).

  Specifically, when the browser unit 133 receives an execution instruction from the AP script (call) 160 or the APDA module 196 that requests processing to the AP providing apparatus 300 during execution of the application program, the browser section 133 performs processing on the AP providing apparatus 300. Create and send an HTTP request to request. At that time, an HTTP request is transmitted to the URI designated in each process.

  Next, when the AP providing apparatus 300 receives the function execution request, the AP providing apparatus 300 executes the function with the execution request (step S9).

  Specifically, the AP execution unit 332 starts executing the process of the AP 360 or DA module (project) 370 associated with the accepted URI. When executing the process of the AP 360, the AP execution unit 332 accesses the database area 324 via the DA module (Wiki) 380 and performs a predetermined data operation.

  Next, the AP providing apparatus 300 calls back a predetermined function to the service user terminal 100 (step S10).

  Specifically, when the AP 360 process is performed, the AP execution unit 332 calls back to display the configured HTML, and when the DA module (project) 370 process is performed, the acquired information is acquired. Form data in JSON format and call back. At that time, the AP execution unit 332 specifies the name of the function to be called back by combining the callback function name added as a parameter to the execution request URI of the AP 360 with the name of the calling application program. In addition, the AP execution unit 332 performs processing using the script library 180 stored in the script library storage area 322 of the AP providing apparatus 300.

  Next, the service user terminal 100 executes a function corresponding to the callback and displays the result (step S11).

  When data is transferred in the JSON format, the browser 133 configures an object based on the data in the JSON format and executes subsequent processing. For example, like the project list callback process 172 which is the second processing content of the AP script (project) 170, an object is formed based on the received JSON format data, and the view object for display using the objectized data is used. Is generated and rendered.

  When the service user terminal 100 receives an instruction for processing to access a database (ticket information database in the present embodiment) in the data storage device 200 during execution of the application program, the service user terminal 100 stores data in the data storage device 200. An access request is transmitted (step S12).

  Specifically, when the browser unit 133 receives an execution instruction of an AP script (ticket) 165 that executes the DSDA module 196 that requests processing of the data storage device 200 during execution of the application program, the browser unit 133 receives the instruction to the data storage device 200. An XML (extensible Markup Language) HTTP request for requesting processing is created and transmitted.

  Next, the data storage device 200 performs data access in accordance with the data access request received in step S12 (step S13).

  Specifically, the data operation unit 232 accesses the database area 221 in accordance with the data access request received in step S12.

  Next, the data storage device 200 returns information on the result obtained by accessing the database in step S13 (step S14).

  Next, the service user terminal 100 executes the continuation of the application process using the data returned in step S14 (step S15).

  The above is the flow of the project management process in the present embodiment.

  FIGS. 16 and 17 show examples of screen display in the project management process.

  FIG. 16 shows a project list display screen 400 as a result of executing the project list processing 171 as the first processing content in the AP script (project) 170.

  The project list screen 400 includes a project name display area 410. In the project name display area 410, all project information stored in the database area 324 of the AP providing apparatus 300 as an existing project is displayed with a hyperlink. In FIG. 16, a speech synthesis service project 402 and a budget management project 403 are shown.

  When any project name is clicked, the browser unit 133 activates a process for displaying details of the corresponding project, for example, a project display process 173 that is the third process content of the AP script (project) 170.

  FIG. 17 is an example of a ticket display screen 410 obtained as a result of displaying ticket information issued in the project on the detailed display screen of the speech synthesis service project 402 described above. The ticket display screen 410 is displayed as a result of the ticket list process 166 which is the first process content in the AP script (ticket) 165.

  The ticket display screen 410 includes a ticket display area 411 and a new ticket generation link display 414 that accepts an input of an instruction to generate a new ticket.

  The ticket display area 411 is an area for displaying all the ticket information stored in the ticket information database in the database area 221 of the data storage device 200. In FIG. 17, the ticket display area 411 displays, as existing tickets, a ticket 412 related to a bug in which sound is interrupted and a ticket 413 related to a bug in which sound is not reproduced.

  When the browser unit 133 receives an input for the ticket in the ticket display area 411, the browser unit 133 displays a screen for displaying detailed information of the ticket that has received the input.

  When the browser unit 133 receives an input to the new ticket generation link display 414, the browser unit 133 executes a process for generating a new ticket, for example, a ticket generation process 167 that is the second processing content of the AP script (ticket) 165. To do.

The reference AP refers to an application that generates an AP script and an AP 360 that are applications that are read and processed by the browser unit 133 of the service user terminal 100. The reference AP is an application that completes processing on the service user terminal 100 except for data access processing. For example, the reference AP is an application written in JavaScript or the like, which is assumed to be executed by the browser unit 133. Among the processes included in the reference AP, the process for accessing the database, that is, the process related to CRUD (Create, Read, Update, Delete) of the data to be used is different when the devices where the database is arranged are distributed. Although processing is requested from the apparatus, other processes other than CRUD included in the application are described so as not to request processing from other apparatuses.

The process includes a process of newly adding ticket information to the database area 221 of the data storage device 200 and a process of acquiring ticket information stored in the database area 221 and generating list information.

  The project list process 554 as the fourth process content of the project management AP 550 will be described. When executed, the project list processing 554 requests the data storage device 200 for the list information of the already generated project management information, and the project management information list acquired by the request is sent to the HTML page including the project management AP 550. Is added and displayed.

  Next, the project display process 555 which is the fifth process content of the project management AP 550 will be described. When executed, the project display process 555 requests the data storage device 200 for the project management information of the project having the identifier specified in the argument, and the project management acquired by the request is sent to the HTML page including the project management AP 550. Information is added and displayed.

  Next, a project generation process 556 as the sixth process content of the project management AP 550 will be described. When executed, the project generation process 556 requests the data providing apparatus 200 to generate and store new project management information, and the requested project management information is added to the HTML page including the project management AP 550. The project list information in the state of being displayed is displayed. The process includes a process of storing new project management information in the database area 221 of the data storage device 200, delegating the process to the project list process 554, and displaying the result.

  The script library storage area 522 stores a script library 180 including a utility program that supports execution of the reference AP.

  The script library 180 is the same as the script library 180 stored in the AP script storage area 121 of the service user terminal 100 described above.

  The DA module storage area 523 stores DA modules. The DA module stored in the DA module storage area 523 is a DA module generated by the DA module generation unit 532 described later. In this embodiment, the DA module is described by JavaScript that is interpreted and executed by the AP execution unit 332, but is not limited to this, and the AP script executed by the service user terminal 100 or the APP providing apparatus 300. If it can be called from the AP 360, it may be described in another language.

  In the AP execution location storage area 524, an AP execution location table 560 is stored.

  The AP execution location table 560 is a table used when the AP generation unit 531 generates an AP script and an AP 360 from the reference AP 550. The AP execution location table 560 stores, for each process of the reference AP 550, a location where the process is executed and a URL which is access information necessary for executing the process.

  FIG. 20 shows a configuration example of the AP execution location table 560.

  The AP execution location table 560 includes a process name column 561, an execution location column 562, and a URL column 563.

  In the process name column 561, the name of the process included in the reference AP 550 is stored.

  The execution place column 562 stores a place where the generated process corresponding to the process of the reference AP 550 is executed. For example, information specifying the service user terminal 100 or the AP providing apparatus 300 is stored as a place to be executed.

  The URL column 563 stores a URL for executing the generated process corresponding to the process of the reference AP 550.

  For example, a record in which “Wiki display processing” is stored in the process name column 561, “AP providing apparatus” is stored in the execution location column 562, and “http: // earth: 3000 / wikis / show” is stored in the URL column 563 is a reference. The “Wiki display process” of the AP 550 is generated as an AP 360 executed by the “AP providing apparatus”, and the URL for executing the process is “http: // earth: 3000 / wikis / show”. Indicates.

  In the module list storage area 525, a data location table 600 and a module list 610 are stored.

  The data location table 600 is a table used when the DA module generation unit 532 generates the DSDA module 190, the APDA module 196, the DA module (project) 370, and the DA module (Wiki) 380. The data location table 600 stores a URL indicating the location of the database for each database.

  FIG. 21 shows a configuration example of the data location table 600.

  The data location table 600 includes a data name column 601 and an arrangement location (URL) column 602.

  The data name column 601 stores the name of the data accessed in the process of the reference AP 550 (database name).

  The arrangement location column 602 stores information (URL) indicating the arrangement location of the database in which data accessed in the process of the reference AP 550 is stored.

  The module list 610 is a table used when the DA module generation unit 532 generates the DSDA module 190, the APDA module 196, the DA module (project) 370, and the DA module (Wiki) 380. The module list 610 stores the name of the DA module for accessing the database for each database.

  FIG. 22 shows a configuration example of the module list 610.

  The module list 610 includes a data name column 611 and a module name column 612.

  The data name column 611 stores the name of the data (database name) accessed in the process of the reference AP 550.

  The module name column 612 stores information such as a name for identifying the DA module.

  Returning to the description of FIG.

  The control unit 530 includes an AP generation unit 531 and a DA module generation unit 532.

  The AP generation unit 531 includes a reference AP 550 stored in the reference AP storage area 521, an AP execution location table 560 stored in the AP execution location storage area 524, and a data location table 600 stored in the module list storage area 525. Are used to generate an AP script that operates on the service user terminal 100 and an AP 360 that operates on the AP providing apparatus 300.

  The DA module generation unit 532 generates a DSDA module 190, an APDA module 196, a DA module (project) 370, and a DA module (Wiki) 380 using the module list 610 and the data location table 600. To do.

  The input unit 541 receives input of information from the operator.

  The output unit 542 outputs information.

  A hardware configuration of the development support apparatus 500 of this embodiment will be described.

  In the present embodiment, the development support apparatus 500 is a computer such as a client PC (personal computer), a workstation, a server apparatus, various mobile phone terminals, or a PDA (Personal Digital Assistant).

  The development support apparatus 500 has basically the same configuration as the service user terminal 100 shown in FIG. However, it is different in that the communication device 116 is not provided.

  The AP generation unit 531 and the DA module generation unit 532 of the development support apparatus 500 are realized by a program that causes the arithmetic device 113 in the development support apparatus 500 to perform processing.

  This program is stored in the main storage device 114 or the external storage device 115, loaded onto the main storage device 114 for execution, and executed by the arithmetic device 113.

  Further, the storage unit 520 of the development support device 500 is realized by the main storage device 114 or the external storage device 115 in the development support device 500.

  The input unit 541 of the development support apparatus 500 is realized by the input device 111 in the development support apparatus 500.

  The output unit 542 of the development support apparatus 500 is realized by the output device 112 in the development support apparatus 500.

  Next, AP generation processing of the development support apparatus in the present embodiment will be described with reference to FIG.

  FIG. 23 is a diagram illustrating a process flow of the AP generation process.

  The AP generation process is performed when the input unit 541 of the development support apparatus 500 receives a process start instruction.

  First, the AP generation unit 531 specifies the first function described in the reference AP 550 as a target function (step S101).

  For example, when the AP generation unit 531 reads the reference AP 550 stored in the reference AP storage area 521 and reads the functions in the order described, the AP generation unit 531 identifies the first described function as the target function.

  Next, the AP generation unit 531 specifies the execution location of the target function specified in step S101 (step S102).

  Specifically, the AP generation unit 531 selects a record in which the name of the target function identified in step S101 matches the value in the process name column 561 of the AP execution location table 560 stored in the AP execution location storage area 524. The execution location stored in the execution location column 562 is specified.

  Next, the AP generation unit 531 determines whether or not the execution location specified in step S102 is a user terminal (step S103).

  When the execution location is not the user terminal (“No” in step S103), the AP generation unit 531 generates the target function as the AP 360 of the AP providing apparatus 300, and the service user terminal 100 that is a script for calling the AP 360. AP script (call) 160 is generated. Then, the process proceeds to step S108 described later (step S104).

  Specifically, the AP generation unit 531 stores the AP 360 in which the processing content of the target function is the processing content as it is in the reference AP storage area 521. Then, the AP generation unit 531 generates a process for calling the AP 360 from the browser unit 133 of the service user terminal 100 according to a fixed form. At that time, a process is generated so as to call the AP 360 using the URL stored in the URL column 563 of the AP execution location table 560. The generated process is stored in the reference AP storage area 521 as an AP script (call) 160. Then, the process proceeds to step S108 described later.

  If the execution location is the user terminal (“Yes” in step S103), the AP generation unit 531 searches the processing content of the target function and determines whether the data to be accessed is data stored on the AP providing apparatus 300. It is determined whether or not (step S105).

  Specifically, the AP generation unit 531 performs processing that executes any one of predetermined functions such as “find”, “find_all”, “save”, and “destroy” in processing within the target function. If there is, specify the object that executes the function. Then, the AP generation unit 531 specifies a record corresponding to the specified object name and the value stored in the data name column 601 of the data location table 600 from the data location table 600, and the arrangement location (URL). It is determined whether or not the value stored in the column 602 indicates the AP providing apparatus 300.

  If the data to be accessed is not data stored on the AP providing apparatus 300 (“No” in step S105), the AP generation unit 531 generates an AP script of the service user terminal 100 having the processing content of the target function. To do. Then, the process proceeds to step S108 described later (step S106).

  Specifically, the AP generation unit 531 generates an AP script that uses the processing content of the target function as it is, and stores it in the reference AP storage area 521. Then, the process proceeds to step S108 described later.

  When the data to be accessed is data stored on the AP providing apparatus 300 (“Yes” in step S105), the AP generation unit 531 generates a callback function based on the target function and uses the service. To the AP script of the user terminal 100. Then, the AP generation unit 531 adds the target function to the AP script of the service user terminal 100 (Step S107).

  Specifically, the AP generation unit 531 searches the processing content of the target function, cuts out the processing described after the processing following the data access processing, and generates it as a callback function. Then, the AP generation unit 531 adds the generated callback function to the AP script of the user terminal 100. Then, the AP generation unit 531 cuts out the process described before the process of performing data access of the target function, and generates the AP script of the service user terminal 100. Then, the AP generation unit 531 stores the generated AP script in the reference AP storage area 521.

  If the processing content of the target function includes loop control (for loop control), the AP generation unit 531 generates an AP script according to the loop conversion processing flow shown in FIG.

  Here, the loop conversion processing flow of FIG. 24 will be described.

  First, the AP generation unit 531 adds an anonymous function corresponding to the for loop block included in the function of the reference AP 550 to the AP script. Then, the AP generation unit 531 adds the variable of the for loop block included in the function of the reference AP 550 as a variable of the anonymous function (step S121).

  Next, the AP generation unit 531 divides the processing included in the for loop block included in the function of the reference AP 550 into detailed blocks (step S122).

  Specifically, the AP generation unit 531 performs processing from the first line of the process included in the for loop block included in the function of the reference AP 550 to the line describing the process for calling the process of the AP providing apparatus 300 first. Specify as one detail block. Then, the AP generation unit 531 performs the second process from the line next to the line describing the process of calling the AP providing apparatus 300 to the line describing the process of calling the AP providing apparatus 300. Identified as a detailed block. Similarly, the AP generation unit 531 divides the process included in the for loop block into detailed blocks until the last line of the process included in the for loop block is reached.

  Next, in step S122, the AP generation unit 531 determines whether or not the for loop block has been divided into two or more detailed blocks (step S123).

  When the for loop block is not divided into two or more detailed blocks (“No” in step S123), the AP generation unit 531 adds an internal function to the anonymous function added in step S121 (step S124).

  Next, the AP generation unit 531 terminates the processing of the internal function when the internal function processing does not satisfy the same continuation condition as the loop continuation condition of the for loop block included in the function of the reference AP 550. A process is added (step S125).

  Next, the AP generation unit 531 adds all the processes of the for loop block included in the function of the reference AP 550 as the process of the internal function (Step S126).

  Next, the AP generation unit 531 adds a process of incrementing the loop variable and a process of calling the internal function at the end of the process of the internal function, and finishes the loop conversion process (step S127).

  When the for loop block is divided into two or more detailed blocks (“Yes” in step S123), the AP generation unit 531 uses the internal function added to the anonymous function added in step S121 and the number of divided detailed blocks. A small number of callback functions are added (step S128).

  Next, the AP generation unit 531 terminates the processing of the internal function when the internal function processing does not satisfy the same continuation condition as the loop continuation condition of the for loop block included in the function of the reference AP 550. A process is added (step S129).

  Next, the AP generation unit 531 adds the process of the first detailed block among the processes of the for loop block included in the function of the reference AP 550 as the process of the internal function (step S130). At that time, the AP generation unit 531 adds the function name of the first callback function to the parameter of the process for calling the process of the AP providing apparatus 300.

  Next, the AP generation unit 531 adds the processing of the second detailed block to the first callback function added in step S128 (step S131). When two or more callback functions are added in step S128, the third, fourth,..., Nth (N is a natural number of 3 or more) detailed blocks are processed in the second. , Third, ..., (N-1) callback functions. At that time, the AP generation unit 531 adds the function name of the subsequent callback function to the parameter for calling the process of the AP providing apparatus 300.

  Next, the AP generation unit 531 adds a process of incrementing a loop variable and a process of calling an internal function at the end of the process of the last callback function added in step S131, and finishes the loop conversion process. (Step S132).

  The above is the flow of the loop conversion process.

  Returning to the flow of the AP generation process.

  Next, the AP generation unit 531 newly sets a function described next to the target function among the functions of the reference AP 550 as a target function, and returns the control to step S102. If there is no function next to the target function in the reference AP 550, the AP generation process ends (step S108).

  The above is the flow of the AP generation process.

  By performing such an AP generation process, the AP script and AP 360 are generated by separating the process operating on the AP providing apparatus 300 from the reference AP 550 described to operate on the service user terminal 100. Is possible.

  Next, the flow of DA module generation processing in this embodiment will be described with reference to FIG.

  FIG. 25 is a flowchart showing the flow of DA module generation processing.

  The DA module generation process is performed when the input unit 541 of the development support apparatus 500 receives a process start instruction.

  First, the DA module generation unit 532 specifies the module described at the top of the module list 610 as a generation target DA module (step S201).

  Specifically, the DA module generation unit 532 specifies a DA module having a name described in the module name column 612 as a generation target for the first database described in the module list 610.

  Next, the DA module generation unit 532 specifies the arrangement location of the generation target DA module specified in step S201, accesses the data stored in the data storage device 200 from the service user terminal 100, and the service. APDA module 196 that accesses data stored in AP providing apparatus 300 from user terminal 100 and DA modules 370 and 380 that access data stored in AP providing apparatus 300 from AP providing apparatus 300 are generated ( Step S202).

  Specifically, when generating the generation target DA module identified in step S201, the DA module generation unit 532 implements a different access method depending on the location of the database accessed by the generation target DA module. A plurality of DA modules are generated. In the present embodiment, the DA module generation unit 532 provides the DSDA module 190 that accesses the data stored in the data storage device 200 from the service user terminal 100 and the AP provided from the service user terminal 100 for the generation target DA module. A DA module corresponding to four patterns of access, that is, an APDA module 196 that accesses data stored in the device 300 and a DA module 370 and 380 that accesses data stored in the AP providing device 300 from the AP providing device 300. Generate.

  Next, the DA module generation unit 532 determines whether or not there is a record to be the next target module in the module list 610. If there is no record to be the target module (if “No”), the DA module generation processing is performed. The process ends (step S203).

  If there is a record to be a target module (“Yes” in step S203), the DA module generation unit 532 reads the next target module from the module list 610, newly specifies it as a generation target DA module, and performs control in step S202. To return.

  The above is the processing flow of the DA module generation processing.

  By performing the DA module generation process, it is possible to generate a plurality of DA modules that access a single database using a plurality of access methods.

  That is, there is a user organization 10 that does not use the database (the project information database and the Wiki database in this embodiment) provided by the AP providing apparatus 300 but uses the original project information database and the Wiki database in the data storage apparatus 200. Even in this case, since the DA module when the project information database is in the data storage device 200 is also generated by the DA module generation process, there is no problem from the service user terminal 100 belonging to the user organization 10 without any problem. Application services provided by the providing apparatus 300 can be used.

  The above is the first embodiment.

  According to the first embodiment, the application provider organization 30 uses an application service as a service without publishing a process including information to be kept secret such as know-how, management information, and a program for providing the application service. Can be provided to the user terminal 100.

  In addition, the user organization 10 can receive an application service provided by the application provider organization 30 while preventing information that the third party does not want to know from leaking to the application provider organization 30. .

  The data provider organization 20 is assumed to be an organization belonging to the user organization 10 in the above embodiment, but is not limited thereto. That is, the data provider organization 20 may be an independent organization different from the user organization 10. Alternatively, an organization belonging to the application provider organization 30 may be used.

  Subsequently, a second embodiment of the present invention will be described.

  The distributed information processing system 1 in the present embodiment has basically the same configuration as the distributed information processing system 1 in the first embodiment.

  However, the distributed information processing system 1 in the second embodiment has the following differences from the distributed information processing system 1 in the first embodiment.

  The distributed information processing system 1 according to the second embodiment includes a database area corresponding to the database area 221 in the storage unit 120 of the service user terminal 100 as an apparatus corresponding to the data providing apparatus 200. A data operation unit corresponding to the data operation unit 232 is provided. In addition, the control unit 330 of the AP providing apparatus 300 includes an initial screen generation unit corresponding to the initial screen generation unit 231.

  In addition, the DA module generated by the development support apparatus 500 performs an API call of a library that supports local database access.

  The difference between the project management process in the second embodiment and the process flow of the project management process in the first embodiment will be described.

  In the project management process in the second embodiment, first, the browser unit 133 of the service user terminal 100 requests an initial page from the AP providing apparatus 300. Then, the AP providing apparatus 300 generates an initial page. Next, the AP providing apparatus 300 transmits the generated initial page to the service user terminal 100 (processing corresponding to steps S1 to S3).

  Henceforth, the process equivalent to step S4 to step S11 is the same as that of 1st embodiment.

  In the processing corresponding to step S12 to step S14, the service user terminal 100 instructs the processing to access the database (the ticket information database in this embodiment) in the service user terminal 100 during the execution of the application program. Is received, a data access request is transmitted to the data operation unit, and the data operation unit performs data access and returns information on the result obtained by the access.

  According to such a second embodiment, the service user prevents the application provider organization 30 from leaking information that should be kept extremely confidential to the application provider organization 30 and the data provider organization 20. It is possible to use the application service provided by.

  Although specific description has been given above based on the embodiment, the present invention is not limited to this, and various modifications can be made without departing from the scope of the invention.

  For example, the development support apparatus 500 according to the first embodiment stores the generated program in the storage unit 520 in the AP generation process and the DA module generation process, but is not limited thereto. That is, the development support apparatus 500 may include a communication unit 543 that can be connected to the inter-organization network 250, and the generated program may be stored in the storage unit 320 of the AP providing apparatus 300.

  By doing in this way, it becomes easy to distribute the generated program to the operation server.

  The distributed information processing system 1 is not only a transaction target as a system, but can also be a transaction target for each device or a program component unit that realizes the operation of each device.
