  FIG. 4 is a flowchart illustrating an example of processing in which the information processing apparatus 101 downloads a document file from the server 102 (hereinafter referred to as document file download processing). FIG. 5 is a diagram illustrating an example of a screen on which the information processing apparatus 101 downloads a document file from the server 102. FIG. 6 is a diagram illustrating an example of a table managed by the information processing apparatus 101 and the server 102.

  In order to use the document system 100, an application (hereinafter referred to as a native application) is installed in the information processing apparatus 101. The user interface in the information processing apparatus 101 uses a Web browser, but it is technically difficult to access a document file stored in the external memory 212 of the information processing apparatus 101 and acquire information related to the document file from the Web browser. Therefore, a native application is used for processing that cannot be realized by the Web browser.

  Note that a native application for interacting with the native application of the information processing apparatus 101 may be installed on the server 102. However, the native application is not essential in the server 102, and a Web such as server-side Java (registered trademark) is available. The application may respond to the native application of the information processing apparatus 101. According to this method, since the types of interfaces to the information processing apparatus 101 in the server 102 do not increase, the resources used in the server 102 can be reduced, and the load on the server 102 can be reduced.

  The document file download process will be described with reference to the flowchart of FIG. It is assumed that the following processing is performed by the CPU 201 of the information processing apparatus 101 or the server 102.

  In step S <b> 401, the native application of the information processing apparatus 101 receives input of a user ID and password from the user, and performs login processing to the document system 100. Further, the native application of the information processing apparatus 101 reads the client setting file 650 stored in the external memory 212, and stores a download folder 651, a server name 652, and a server document file output for storing the document downloaded from the server 102. The folder 653 is stored in the RAM 202.

In step S402, the native application of the information processing apparatus 101 transmits a user ID to the server 102, and transmits a request for a document list that can be downloaded by the user. That is, step S402 is a step showing an example of processing for requesting downloadable document file information to the server.
In step S <b> 403, the server 102 receives the user ID and the downloadable document list request transmitted from the information processing apparatus 101.

  In step S404, the server 102 uses the received user ID to acquire a document list that can be downloaded by the user. In order to create the document list, there may be a table for managing the user's download authority for each document file. However, in this embodiment, for the sake of simplicity, all users are all managed by the server 102. A document file related to a document form can be downloaded. The document list is created by externally combining the document master table 610 and the document file table (server) 620.

  Here, each data table will be described. The document master table 610 includes columns of “document form ID 611”, “static flag 612”, and “document form file path 613”, and “document form ID 611” is a main key. “Document form ID 611” is document form identification information for identifying a document form. “Document form file path 613” is a file path in which the form file of the document form is stored. Using this “document form file path 613”, the server 102 acquires a document form file.

  The server 102 creates a document file by overlaying data acquired from a database or the like on the acquired document form file, but the “static flag 612” is static data that does not change depending on the acquisition timing. If the data is “static” or dynamic data that may change depending on the acquisition timing, it is expressed as “motion”. Whether to set “Static” or “Dynamic” may be determined by the document system administrator or the document form creator, or the document form is analyzed and the static data obtained from the definition file for the overlay data is obtained. It is good also as a mechanism which discriminate | determines automatically using judgment criteria, such as static data, dynamic data acquired from a database, or static data acquired from a database, but not updated.

  In other words, a document form having the “static flag 612” of “static” generates a document file with exactly the same content no matter how many times the document file is created. Is stored in the external memory 212 such as an HDD and reused when a request for creating the same document file is received, so that the document file creation process should be performed only once.

  On the other hand, a document form having the “static flag 612” of “moving” is created with a different content every time a document file is created. However, every time a document file creation request is received, a document file creation process must be performed.

  That is, the document master table 610 stores information as to whether or not the information for identifying the update of the document file changes according to the timing created by the server in response to a request from the information processing apparatus in association with the document file identification information. It is a functional part which shows an example of a means.

  In this embodiment, it is assumed that the content of the document file to be created does not depend on the user who makes the document file creation request. That is, when the document file creation processing related to the creation requests from a plurality of users is performed at the same time for the document form with the document form ID 611 = B1, the contents of the created document files are the same.

The document file table (server) 620 includes columns of “document form ID 621”, “document file name 622”, “creation date 623”, and “checksum 624”, and “document form ID 621” is a primary key. “Document file name 622” is document file identification information for identifying a document file created by overlaying data acquired from a database or the like on a document form file. In this embodiment, the document file name is a character string of “document form ID_creation date_serial number on that day” as “A2 — 20140410_301”, but this character string is merely an example, and the created document file is uniquely Any format may be used as long as it can be identified.
“Creation date / time 623” is the creation date / time of the document file in the server 102.

  “Checksum 624” determines whether or not the content of the document file is the same when the document file stored in the server 102 and the document file stored in the information processing apparatus 101 have the same document form ID. This is an error detection code used in order to do this, that is, information for identifying update of a document file, which is a value calculated in or after the creation process of the document file. An error detection code other than a checksum may be used as long as it can be determined whether or not the contents of the document file are the same. That is, in this embodiment, document files having the same checksum value are regarded as document files having the same contents.

  Returning to the description of step S404. In step S404, the document list created by the external combination of the document master table 610 and the document file table (server) 620 is “document form ID 611”, “static flag 612”, “document form file path 613”, “document file name 622”. "Created date 623" and "Checksum 624". The document list is output as “document form ID 511”, “static flag 512”, and “server document file creation date 515” on the document download screen 510 described later.

  In this embodiment, the document list is created by the external combination of the document master table 610 and the document file table (server) 620. However, the present invention is not limited to this method. The document list may be created using information on whether or not the document file exists in a predetermined folder.

Further, the processing of step S404 may be executed by the server 102 without performing the process by logging in directly to the server 102 by the native application of the information processing apparatus 101. In that case, the application of the server 102 that executes the process of step S404 becomes unnecessary.
In step S <b> 405, the server 102 transmits the created document list to the information processing apparatus 101.

  In step S406, the native application of the information processing apparatus 101 receives the document list and stores the received document list in the external memory 212. That is, step S406 is a step showing an example of a process for acquiring requested document file information.

  In this embodiment, a document list request is transmitted to the server 102 from the native application of the information processing apparatus 101 in step S402, and the document list transmitted from the server 102 is transmitted to the server 102 in step S406. Although it is assumed that the native application receives, this is merely an example, and the present invention is not limited to this. That is, the native application of the information processing apparatus 101 may directly log in to the server 102 using the user ID and password, and the native application itself may acquire the document list of the server 102. According to this method, the server 102 can concentrate on the creation of the document file, and the load on the server 102 can be reduced.

  In step S407, the native application of the information processing apparatus 101 acquires the value of the download folder 651 from the RAM 202, and acquires the document file information stored in the file path of the download folder 651 of the external memory 212, whereby the document A file information list table “document file table (client) 630” is created in the RAM 202.

  Here, the document file table (client) 630 will be described. The document file table (client) 630 includes columns of “document form ID 631”, “document file name 632”, “creation date / time stamp 633”, and “checksum 634”, and “document form ID 631” is a primary key.

  The “creation date and time stamp 633” indicates the date and time when the document file was created in the server 102, and is not the date and time when the document file was created in the download folder 651 of the external memory 212 of the information processing apparatus 101. “Checksum 634” is a checksum of the document file, and is calculated in step S407. That is, step S407 is a step showing an example of processing for acquiring information for identifying an update for each stored document file.

  In step S408, the native application of the information processing apparatus 101 records that the document form ID 621 of the document list received from the server 102 in step S406 matches the document form ID 631 of the document file table (client) 630 created in step S407. Are compared with the creation date / time 623 and the creation date / time stamp 633, and the checksum 624 and the checksum 634, respectively.

  That is, in step S408, if the document file identification information included in the document file information acquired from the server matches the document file identification information of the document file stored in the storage unit 301, the document file information acquired from the server is updated. It is a step showing an example of processing for comparing the information for identifying the update of the document file included with the information for identifying the update of the document file corresponding to the acquired document file identification information.

  In step S408, if the document file identification information included in the document file information acquired from the server 102 matches the document file identification information of the document file stored in the storage unit 301, the document file information acquired from the server. Is a step showing an example of a process for comparing the creation date and time of the document file included in the document file and the creation date and time of the document file stored in the storage unit 301.

In step S409, the information processing apparatus 101 displays the document download screen 510 (FIG. 5) on the Web browser. That is, step S409 is a step showing an example of processing for identifying and displaying a list of document file identification information of document files determined to be updated based on the comparison result in step S408. Step S409 is a step showing an example of a process for identifying and displaying a list of document file identification information having different creation dates and times.
Hereinafter, each display item will be specifically described.

  In the document form ID 511, the document form ID 611 of the document list received from the server 102 in step S406 is displayed as document form identification information. That is, the user can understand that the document file related to the document form ID 511 can be downloaded.

  In the static flag 512, the static flag 612 of the document list received from the server 102 in step S406 is displayed. As a result, when the user sees the static flag 512 and there is a document file related to the document form in which “static” is displayed locally, there is no need to newly download, and “dynamic” is displayed. If the document file related to the document form exists locally, it can be understood at a glance that the document file may already be old information.

  In the local document file creation date / time stamp 513, the creation date / time stamp 633 of the document file table (client) 630 created in step S407 is displayed. If the local document file creation date and time stamp 513 is blank, the document file does not exist in the download folder 651 of the information processing apparatus 101, and the user has never downloaded the document file related to the document form, or You can understand at a glance that it was deleted or moved after downloading.

  In the date / time comparison 514, the creation date / time stamp 633 and the size of the creation date / time 623 compared in step S408 are displayed using “<” and “=”. That is, the creation date / time stamp 633 is older than the creation date / time 623 (= a document form in which a document file is requested to be created by another user after the user downloads, or a document form in which the document file does not exist locally and exists in the server ), And “=” is displayed when the creation date / time stamp 633 is equal to the creation date / time 623 (= a document form for which no other user has requested creation after the creation request of the user).

  In the server document file creation date 515, the creation date 623 of the document list received from the server 102 in step S406 is displayed. If the server document file creation date and time 515 is blank, it means that the document file related to the document form does not exist in the server 102, and thus the document file has not been created so far.

  If the value of the checksum 624 compared with the value of the checksum 634 compared in step S408 is different from the file difference 516, that is, if the contents of the server document file are updated from the local document file, “! Is displayed. Even when the date comparison 514 is “<”, if the file contents are equal, “!” Is not displayed and “blank” is set. For a document form with a static flag 512 of “static”, “/” is displayed because the local document file and the server document file always have the same contents. It is also set to “blank” when there is no local document file.

  Thereby, the user can understand at a glance that the contents of the local document file are already old information in the document form in which “!” Is displayed in the file difference 516. However, the document form that is “blank” has only the same content as the document file that exists at that time on the server, and it is not known whether the content of the local document file is the latest information. That is, after that, when the document file related to the document form is created on the server and the document download screen 510 is redrawn, the contents of the local document file become old information.

  The selection check box 517 can be turned ON / OFF by being pressed by the user, and then the document file related to the document form checked by pressing the “RE batch download” button 522 is downloaded. Can be requested. That is, the selection check box 517 is an example of an instruction unit that instructs a document file to be downloaded among the document files displayed in a list or cancels the instruction.

  The individual download button 518 is not displayed on the document form in which the static flag 612 = “static” and the local document file exists, but is displayed on other document forms. When the individual download button 518 is pressed, a plurality of document files can be downloaded individually rather than collectively. The individual download button 518 is not displayed for the document with the document form ID = “A3”. The static flag 612 of the “A3” document = “static”, that is, the data in the document does not change depending on the acquisition timing. This is because it is static data and there is a local document file, so there is no need to download it separately.

  A “battery batch download” button 519 can be pressed to request batch download of document files related to a document form for which no local document file exists. Thereby, since many document files can be downloaded together, the convenience of document file download can be improved in a state where there are few document files locally.

  When the “moving and roving batch download” button 520 is pressed, it is possible to request batch downloading of document files relating to a document form in which the static flag 512 = “moving” and the local document file exists. As a result, since dynamic document files that have been downloaded so far can be downloaded together, the convenience of downloading a document file that may be updated can be improved.

  The “! Batch download” button 521 can be pressed to request batch download of document files related to the document form with the file difference 516 = “!”. As a result, document files that are clearly old information can be updated together, and the convenience of downloading a document file that needs to be updated can be improved.

  By pressing the “re batch download” button 522, it is possible to request batch download of document files related to the document form in which the selection check box 517 is checked. As a result, the document files desired by the user can be updated together, and the convenience of downloading the document file can be improved.

  Note that, in the above, pressing the “battery-less batch download” button 519, the “active & random batch download” button 520, and the “! Batch download” button 521 requests to download a document file that meets the respective conditions. However, the present invention is not limited to this method, and when the “battery-free batch download” button 519, “motion & rolly-all batch download” button 520, and “! The download may be started only after the selection check box 517 of the applicable document form is automatically selected and then the “le batch download” button 522 is pressed.

By doing so, after the selection check box 517 is automatically selected by pressing the “batch download” button, the check can be turned on / off by the user, so that more flexible downloading is possible, and the document file The convenience of downloading can be improved.
An end button 523 can be pressed to close the document download screen and end the document file download process.

In step S410, the information processing apparatus 101 receives a user operation and determines the received operation. If a predetermined time (for example, 1 minute) elapses in step S410, the process returns to step S412 to request information on the downloadable document of the server 102 again.
If the selection check box 517 is pressed in step S410, the pressed check is switched ON / OFF, and the process returns to step S410. If the end button 523 is pressed, the process proceeds to step S432.

  If the download buttons 518 to 522 are pressed in step S410, the process proceeds to step S411. That is, step S410 is a step showing an example of processing for instructing downloading of a document file via a list screen displayed as a list.

  Further, the download process in step S410 after the “battery-less batch download” button 519 is pressed is a step showing an example of a process for instructing download of a document file not stored in the information processing apparatus.

  In addition, the download process in step S410 after the “dynamic & random download” button 520 is pressed is a document stored in the information processing apparatus and indicating that the information for identifying the update of the document file changes depending on the timing. It is a step which shows an example of the process which instruct | indicates download of a file.

  The download process in step S410 after the “! Batch download” button 521 is pressed is a step showing an example of a process for instructing download of a document file having different information for identifying update of the document file.

  In addition, the download process in step S410 after the “re batch download” button 522 is pressed is an example of a process for downloading the instructed document file.

  The document download screen 510 instructs to download a plurality of document files via the list screen, or includes both a download instruction for one document file and a download instruction for a plurality of document files via the list screen. It is an example.

  In step S411, the native application of the information processing apparatus 101 repeats the processing in steps S412 to S416 for the number of document files to be downloaded. At this time, if the individual download button 518 is pressed, the document form ID and the document file name related to the pressed individual download button 518 are acquired from the document list stored in the external memory 212. If the “collective download” button 519 to 522 is pressed, the document form ID and document file name of the document corresponding to each button are acquired from the document list stored in the external memory 212.

  In step S <b> 412, the native application of the information processing apparatus 101 determines whether a document file related to the document form to be downloaded exists in the server 102. When it exists in the server 102, it progresses to step S413. If the server 102 does not exist, the process proceeds to step S416.

  In step S413, the native application of the information processing apparatus 101 determines whether the static flag 512 of the document form to be downloaded is “static” or “dynamic”. In the case of “static”, the process proceeds to step S414. In the case of “motion”, the process proceeds to step S415.

  In step S414, the information processing apparatus 101 displays a download confirmation dialog 530 on the display 211, and determines that the user has pressed the button. If the “download document file existing in server 102” button 531 is pressed, the process advances to step S415. If the “create latest file and download” button 532 is pressed, the process proceeds to step S416. That is, step S414 is a step showing an example of processing for allowing the user to select whether to download a document file that exists in the server without re-creating the document file, or to re-create and download the document file. is there.

  In step S415, the native application of the information processing apparatus 101 adds the document file name to the list of documents to be downloaded. This is because a new document file is not created in the server 102 but an existing document file is downloaded, so that the document file name is designated. In the case of “batch download” buttons 519 to 522, the document file names of all documents corresponding to the respective buttons are added to the list of documents to be downloaded. By making a download request using a document file name, it becomes possible to download an existing document file without creating a new document file, thereby reducing the load related to the document file creation processing of the server 102. Can do.

  In step S416, the native application of the information processing apparatus 101 adds “document form ID_document file checksum related to the document form ID existing locally” to the list of documents to be downloaded. This is because the server 102 newly creates a document file related to the document form ID by specifying the document form ID, compares the created document file with the local checksum, and only the contents are updated. Is to download. In the case of the “collective download” buttons 519 to 522, “document form ID_checksum of document file related to the document form ID existing locally” is downloaded for all documents corresponding to the respective buttons. Add to list. Note that if the document file associated with the document form ID does not exist locally, checksum = 0.

In step S 417, the native application of the information processing apparatus 101 transmits the created download document list to the server 102.
In step S418, the server 102 receives the download document list.
In step S419, the server 102 repeats the processing from step S420 to step S426 by the number of elements in the download document list.
In step S420, the server 102 acquires one element present in the download document list. If the acquired element = document file name, the process proceeds to step S421. If the acquired element = “document form ID_checksum”, the process proceeds to step S422.
In step S421, the server 102 acquires a document file to be downloaded from the document file output folder 641 using the document file name.

  In step S422, the server 102 searches the document master table 610 using the document form ID, acquires the document form file path 613, and acquires the document form file existing in the document form file path 613 from the database or the like. A new document file is created by overlaying the data. At this time, in order to uniquely identify the created document file, the document file name is set as a character string “document form ID_creation date_serial number on that day” and stored in the document file output folder 641 of the server 102.

  In step S423, the server 102 reflects the created document file in the document file table (server) 620. Specifically, when the document file relating to the document form ID is created for the first time, a record is inserted because there is no record of the document form ID in the document file table (server) 620. In the second and subsequent times, the record of the document form ID exists in the document file table (server) 620, so the record is updated. At this time, the checksum of the document file is calculated and stored as the value of “checksum 624”.

  In step S424, the server 102 compares the checksum of the document file related to the document form ID that exists locally in step S420 with the checksum of the document file calculated in step S423, and compares the two checksums. Are equal, the content of the locally existing document file is regarded as equal to the content of the document file created in step S422, and the process proceeds to step S425. If the two checksums are different, the content of the locally existing document file is considered to be different from the content of the document file created in step S422, and the process proceeds to step S428.

  In step S425, the server 102 notifies the information processing apparatus 101 that the content of the locally existing document file is equal to the content of the document file created in step S422.

  In step S426, the information processing apparatus 101 receives a notification that the content of the locally existing document file is equal to the content of the document file created in step S422.

  In step S427, the information processing apparatus 101 displays a download cancel dialog 540 on the display 211, and the newly created document file in the server 102 has the same content as the locally existing document file, so that the download has been canceled. To the user. When the OK button 541 is pressed by the user, if the loop of step S419 continues, the process returns to step S419. If the loop of step S419 ends, the process proceeds to step S431.

  In step S428, the server 102 transmits the document file acquired in step S421 or the document file created in step S422 to the information processing apparatus 101. In this embodiment, even in the case of batch download, the list of documents to be downloaded is downloaded one by one in order. However, the present invention is not limited to this method, and a plurality of document files are combined into one archive file. You may download it.

  In step S429, the native application of the information processing apparatus 101 receives the document file, and stores the received document file in the download folder 651 of the external memory 212. That is, step S429 is a step showing an example of a process of downloading the document file displayed as a list.

  In step S430, the native application of the information processing apparatus 101 reflects the received document file information in the document file table (client) 630. That is, steps S429 and S430 are steps showing an example of processing for storing a document file created and downloaded by the server in response to a request from the information processing apparatus in association with the document file identification information.

Specifically, when the document file related to the document form ID is downloaded for the first time, the record is inserted because there is no record of the document form ID in the document file table (client) 630. In the second and subsequent times, the record of the document form ID exists in the document file table (client) 630, so the record is updated. At this time, the checksum of the document file is calculated and stored as the value of “checksum 634”.

In step S431, the information processing apparatus 101 displays the download completion dialog 550 on the display 211, and when the user presses the OK button 551, the process returns to step S402.
In step S432, the information processing apparatus 101 closes the document download screen displayed on the display 211 and logs out from the document system.
Above, description of the document file download process of FIG. 4 is complete | finished.
Above, description of 1st Embodiment is complete | finished.

[Second Embodiment]
The first embodiment compares information included in document file information stored in an information processing apparatus and document file information that can be downloaded from a server, and lists information for identifying update of the contents of the document file In the second embodiment, in addition to the mechanism of the first embodiment, after the document file information stored in the information processing apparatus is generated, the value of the database used for the document file is updated. This is a mechanism for identifying and displaying a list of existing documents.

  The second embodiment will be described with reference to FIGS. FIG. 7 is a flowchart illustrating an example of processing in which the information processing apparatus 101 according to the second embodiment downloads a document file from the server 102. FIG. 8 is a diagram illustrating an example of a screen on which the information processing apparatus 101 according to the second embodiment downloads a document file from the server 102. FIG. 9 is a diagram illustrating an example of a table managed by the information processing apparatus 101 and the server 102 according to the second embodiment.

  In the second embodiment, the flowchart of FIG. 4 in the first embodiment is replaced with FIG. 7, and the same process as the step of the first embodiment is assigned the same step number and the description is omitted. It is assumed that the following processing is performed by the CPU 201 of the information processing apparatus 101 or the server 102.

  In step S701 in FIG. 7, the server 102 repeats steps S702 to S706 by the number of document forms in the downloadable document list acquired in step S404.

  In step S702, the server 102 determines the value of the static flag 612 included in the document list acquired in step S404. If static, the process proceeds to step S707, and if dynamic, the process proceeds to step S703. For example, when the document form ID 511 = A3, the static motion flag 612 = static, so the process proceeds to step S707. When the document form ID 511 = B6, the static motion flag 612 = dynamic, the process proceeds to step S703.

  In step S703, the server 102 acquires a document form file. Specifically, a document form file is acquired from the external memory 212 using the document form file path 613 included in the document list acquired in step S404. For example, when the document form ID 511 = B6, the document form file path = D: ¥ FORM ¥ B6.frm is used to obtain the document form file 920 (B6.frm) of FIG. 9 from the external memory 212.

  In step S704, the server 102 analyzes the document form file acquired in step S703. For example, when the document form ID 511 = B6, the contents of the document form file 920 (B6.frm) acquired in step S703 are analyzed.

  In step S705, the server 102 identifies a database record used for document file creation from the contents of the document form file analyzed in step S704. In this embodiment, using the information written in italics in the document form file, the value obtained from the database is output to the italic portion. That is, the document form file is a functional unit that shows an example of a unit that stores a document form including a designation description of data to be referred to in order to create the document file in association with the document file identification information.

  For example, in the document form file 910 (A3.frm), there is an italic description “store table.store name (store ID = X)”, which is searched for the store table 930 in the database with the store ID = X. This means that the acquired store name “Tokyo head office” is output in italics (the output result is the download document file 950 in FIG. 9). As can be seen from the update date and time of the store table 930, this table is not a daily updated table, and the registered records are static data that does not change depending on the acquisition timing. Therefore, the document system administrator or the document form creator sets the static flag 612 of the record with the document form ID 511 = A3 to “static” in the document master table 610.

  Similarly, in the document form file 920 (B6.frm), there is an italicized description “current month sales table.sales amount (store ID = X)”. This is because the current month sales table 940 of the database is stored in the store ID = This means that the sales amount “¥ 1,230,000” retrieved by X is output in italics (the output result is the download document file 960 in FIG. 9). As can be seen from the update date and time of the current month sales table 940, this table is a table that is updated at any time, and the registered record is dynamic data that changes depending on the acquisition timing. For this reason, the document system administrator or the document form creator sets the static flag 612 of the record of the document form ID 511 = A3 to “dynamic” in the document master table 610.

  That is, in step S705, it can be specified that the store ID = X, Y, and Z records of the “current month sales table” are used to create the document file with the document form ID 511 = B6.

  In step S706, the server 102 searches the database record used for creating the document file specified in step S705, acquires the latest update date and time among the target records, and corresponds to “document form ID 611” in the document list. It is added to the document list as “database update date”. That is, step S706 is a step showing an example of a process for obtaining the data update date and time using the designation description of the data to be referenced included in the document form. Step S706 is an example of processing for obtaining the update date of the data by using the data specification description included in the document form when the information for identifying the update is a document file that changes depending on the timing. It is the step shown.

  For example, a record of store ID = X, Y, Z in the “current month sales table” used for creating a document file of document form ID 511 = B6 is searched, and the latest update date “2014/4/10 17 among these records”. : 30 ”is acquired and added to the document list as“ document update ID ”= 2014/4/10 17:30 corresponding to“ document form ID 611 ”= B6 in the document list.

  In step S708, the native application of the information processing apparatus 101 records that the document form ID 621 of the document list received from the server 102 in step S406 matches the document form ID 631 of the document file table (client) 630 created in step S407. Are compared with the creation date / time 623 and the creation date / time stamp 633, the checksum 624 and the checksum 634, and the database update date / time and the creation date / time stamp 633, respectively.

  That is, in step S708, if the document file identification information included in the document file information acquired from the server matches the document file identification information of the document file stored in the information processing apparatus, the document file information acquired from the server is updated. Compares the update date / time of the included data with the creation date / time when the document file was created on the server in response to a request from the information processing device included in the document file information or the creation date / time of the document file acquired from the information processing device It is a step which shows an example of a process.

In step S709, the information processing apparatus 101 displays a document download screen 810 (FIG. 8) on the Web browser. That is, step S709 determines that the update date / time is newer than the creation date / time when the document file was created by the server or the creation date / time of the document file acquired from the server in response to a request from the information processing device included in the document file information. 11 is a step showing an example of a process of identifying and displaying a list of document file identification information of a document file that has been read.
Hereinafter, each display item in FIG. 8 that is not in FIG. 5 will be described in detail.

  In “DB difference 811”, if the result of comparison in step S708 shows that the creation date of the document file <the data update date of the database, that is, the database target data is updated after the creation date of the local document file. If it is, “★” is displayed. If “document file creation date / time” ≧ “database data update date / time”, that is, if the target data in the database has not been updated after the local document file creation date / time, “blank” is set.

  For a document form having a static flag 512 of “static”, “/” is displayed because the target data in the database is not updated after the creation date and time of the local document file. If the local document file does not exist, “blank” is set.

  In this embodiment, the document file creation processing time is not taken into account, and “★” is displayed when the document file creation date <the database data update date / time, and the document file creation date ≧ database data. If it was the update date and time, it was set to “blank”, but this is not restrictive, taking into account the document file creation processing time, the document file creation date ± document file creation processing time ≤ database data update “★” may be displayed when the date and time are set, and “blank” may be set when the date and time when the document file is created ± the creation time of the document file> the data update date and time of the database. (± means + or-, if document file creation date = document file creation processing time start time +, document file creation date = document file creation processing time end time- And)

  In this embodiment, the “document file creation date / time” is the document file creation date / time acquired from the external memory 212 of the information processing apparatus 101 in step S407. However, the present invention is not limited to this, and step S406 is not limited thereto. Thus, the creation date and time of the document file included in the document file information received from the server 102 may be used. By doing so, when the document file is downloaded, it can be used as a criterion for whether the document file existing in the server 102 should be downloaded or re-created and downloaded.

  In this embodiment, if the creation date of the document file is less than the data update date of the database, “★” is displayed. However, the present invention is not limited to this, and other characters / symbols and database data are displayed. The update date and time may be displayed as it is.

  In addition, “document file creation date and time acquired from the external memory 212 of the information processing apparatus 101 in step S407” <“database data update date and time” ≦ “document file information received from the server 102 in step S406” "Date and time of creation of document file included" may be displayed as "re-download required" because the document file on the server is the latest information.

  On the other hand, if “document file creation date and time included in document file information received from server 102 in step S406” <“database data update date and time”, the server document file is also out of date, so “recreate “Necessary” or “★★” may be displayed. By doing so, when the user instructs to download the document file, it can be used as a criterion for whether to instruct to download the document file existing in the server 102 or to instruct re-creation + download.

  Thereby, the user can understand at a glance that the document form in which “★” is displayed in the DB difference 811 already has the old document file information. Therefore, in the document download screen 510 of the first embodiment, a document form whose file difference 516 is “blank” means that the local document file and the document file existing on the server have the same contents. It is not known whether or not the content of the document file is the latest information. However, when viewing the document download screen 810 of the second embodiment, it can be determined whether or not the content of the local document file is the latest information. In other words, even if the document file related to the document form is not created on the server after downloading the local document file, it can be determined whether or not the content of the local document file is old information.

  The individual download button 812 has a static flag 612 = “static” and a document form in which a local document file exists and a “DB difference 811” = blank (document file creation date ≧ database data update date / time) document form. Is not displayed and is displayed on other document forms. Similar to the individual download button 518 of the first embodiment, the individual download button 812 can be downloaded individually to download a document file. Unlike the first embodiment, the individual download button 812 is not displayed for the document with the document form ID = “B4” because the “DB difference 811” of the “B4” document is blank, that is, a local document file. This is because the content of the latest information is the latest information and does not need to be downloaded again.

  In other words, the individual download button 812 determines that the update date / time is newer than the creation date / time when the document file was created by the server or the creation date / time of the acquired document file in response to a request from the information processing device included in the document file information. On the other hand, the update date and time from the creation date and time when the document file was created on the server in response to a request from the information processing device included in the document file information This is an example of means for instructing download of a document file determined to be old.

  A “dynamic batch download” button 821 can be pressed to request a batch download of document files related to a document form with the static motion flag 512 = “dynamic”. Thereby, since dynamic document files can be downloaded together, the convenience of document file download can be improved.

  A “<batch download” button 822 can be pressed to request batch download of document files related to a document form for which “<” is displayed in the date and time comparison 514. As a result, since the latest document files on the server can be downloaded together, the convenience of document file download can be improved.

  When the “★ batch download” button 823 is pressed, it is possible to request batch download of document files related to the document form of DB difference 811 = “★”. This makes it possible to update the document files related to the document form whose target data in the database has been updated after the creation date and time of the local document file, improving the convenience of downloading the document file that needs to be updated can do.

  If the download buttons 518 to 522, the “dynamic batch download” button 821, the “<batch download” button 822, and the “★ batch download” button 823 are pressed in step S410 in the second embodiment, the process proceeds to step S411.

  That is, the download process in step S410 after the “dynamic download” button 821 is pressed indicates that the information included in the document file information for identifying the update of the document file changes depending on the timing created by the server. It is a step which shows an example of the process which instruct | indicates download of a document file.

In addition, the download processing in step S410 after the “<batch download” button 822 is pressed, the creation date and time of the document file included in the document file information acquired from the server from the creation date and time of the document file stored in the storage unit 301. 11 is a step showing an example of a process for instructing download of a document file determined to be new.

In addition, the download processing in step S410 after the “★ batch download” button 823 is pressed is acquired from the creation date / time when the document file was created by the server in response to a request from the information processing apparatus included in the document file information or from the server This is a step showing an example of processing for instructing download of a document file whose update date / time is determined to be newer than the creation / date of the document file included in the document file information.
This is the end of the description of the process in which the information processing apparatus 101 according to the second embodiment in FIG. 7 downloads the document file from the server 102.
This is the end of the description of the second embodiment.

  As described above, by comparing the information included in the document file information stored in the information processing apparatus and the document file information that can be downloaded from the server, a list of information for identifying the update of the contents of the document file is displayed. The convenience of document file download can be improved.

  In addition, useful information (static flag, document file creation date / time, date / time comparison, file content difference, difference from DB) is displayed in a list for the user who wants to download the document file, thus reducing unnecessary downloads. Therefore, it is possible to reduce the server load related to the processing in which the server repeatedly creates a document file having the same content and transmits it to the information processing apparatus. That is, the number of file creation processes and download processes for document files in the server can be reduced, and the load on the server and the network can be reduced.

  In addition, since the contents of the document file downloaded to the information processing apparatus can be easily compared with the contents of the document file created on the server, it is possible to know that the contents have been updated without downloading. it can.

  In addition, the creation date of the document file downloaded to the information processing device or the creation date of the document file created on the server can be easily compared with the update date of the database data. Even without this, it is possible to know that the data used in the document file has been updated in the database.

  In addition, since the user can download the document files at a time without selecting the document files whose contents may be updated one by one, the convenience of downloading the document files can be improved.

  In addition, when the user who uses the information processing apparatus wants to update the document file downloaded in advance to the latest state, an operation that the document file must be selected and downloaded from the server one by one. In this document system, troublesome issues can be downloaded only in advance, only documents that have been downloaded in advance, and only documents that differ from document files created on the server in advance. Since only the documents whose data used in the document file is updated in the database can be downloaded in a batch, the problem can be solved.

  As described above, a recording medium that records a program that implements the functions of the above-described embodiments is supplied to a system or apparatus, and a computer (or CPU or MPU) of the system or apparatus stores the program stored in the recording medium. It goes without saying that the object of the present invention can also be achieved by reading and executing.
