[0001]
BACKGROUND OF THE INVENTION
The present invention performs various processes such as referencing, changing, adding, and searching a file (table or database data) stored in a server computer (hereinafter simply referred to as a server) from a client computer (hereinafter simply referred to as a client). With regard to file processing technology in C / S (client / server) that makes it possible, in particular, a general-purpose client machine and software (browser) can be used, and a new program is introduced when a C / S system is introduced. The present invention relates to a file processing method that can eliminate the need for development, a device for realizing the processing method, and a computer-readable recording medium that records the processing procedure of the processing method as a program code.
[0002]
[Prior art]
In recent years, a C / S (client / server) system composed of a server that manages information and resources and a client that makes a request to the server and uses the information and resources has become widespread. In a conventional C / S system, an input screen is created based on the specifications of the clients that make up the system, and the input made using the input screen is sent to the server, so that desired access to the server is achieved. Every time a system was constructed, it was necessary to develop a program for it.
[0003]
A C / S system using WWW (World Wide Web) is also known. For example, an editor: NEC Intranet Project “Intranet Complete Construction Guide” (December 25, 1996, Nikkei Business Publications, Inc.), JP-A-8- This is disclosed in Japanese Patent No. 320846. From page 49 to page 50 of the former "Intranet Complete Construction Guide", a menu screen and search condition input screen can be sent to the WWW server by specifying a URL (Uniform Resource Locator) on the browser on the client side. Request, WWW server sends requested HTML document to browser side, browser receives and displays it, CGI (Common Gateway Interface) program that WWW server software executes search when search condition is input Is started, the database is accessed, the search result is converted into an HTML document, downloaded again to the client side, and displayed on the browser on the client side.
[0004]
In the latter Japanese Patent Application Laid-Open No. 8-320846, the server provides the user with hypertext in which the dialogue ID is added to the URL at the initial stage of access from the user, and thereafter the client uses the URL with this ID. In this way, what enables advanced access control is described.
In general, when using the Internet, client machines and browsers are versatile, but programs for searching and counting questionnaires are difficult to build with HTML alone, requiring a skilled programmer who is familiar with CGI programs and the like. It was.
[0005]
[Problems to be solved by the invention]
As described above, in the conventional C / S system, it is necessary to create an input screen for each system so as to be adapted to the specific system configuration. There was a problem that the machine of this was limited.
[0006]
In addition, when using the Internet, there is no limitation on the machine on the client side, but it is quite difficult to describe the linkage with the database in HTML, and a CGI program etc. can be used to collect data such as search functions and questionnaires using only HTML. There was a problem that it could only be created by a skilled programmer who was familiar with it.
In the present invention, in order to solve the above problems, it is not necessary to newly create a special program, and various processes (search, input, etc.) are designated by selecting and inputting items on a screen from a general-purpose browser. Simply by causing the server to execute the process, displaying the execution result on the client, and inputting new data (addition, change, etc.) to the file, and a device for realizing the method, and an apparatus for realizing the method, and A computer-readable recording medium on which the processing procedure of the processing method is recorded may be provided.
[0007]
[Means for Solving the Problems]
In order to achieve the above object, file processing using the Internet in the present invention is performed in the following procedure.
First, when the client (10) requests the server (20) to display the initial screen, the server (20) automatically adds a display / update button (to that effect when the button is selected) to the URL. An initial screen including the function is generated and returned (initial screen generation unit 22). The client (10) selects a file display / update button on the initial screen, adds it to the URL, and sends it to the Internet (30). When the server (20) receives a URL to which a file display / update request is added from the client (10), the server (20) automatically adds a file list (the selected file name and a specific extension to the URL). When a function and a processing type are input, the processing type is automatically added to the URL after the file name and a specific extension) and returned to the client (file list generation unit 24) . In the client (10), one file name selected from the displayed file list and a specific extension are added to the URL and sent to the Internet (30), or one selected from the file list is sent. In addition to one file and a specific extension, a processing type (search, addition, update, etc.) is added to the URL and sent to the Internet (30). If the processing type is search, a search condition (parameter) is added.
[0008]
In the server (20), when only a file name with a specific extension added to the URL is added, the file is read out and sent to the client (10), and the file with the specific extension added to the URL When a process type is added in addition to the name, the process is executed based on the process type added to the file, and the execution result is returned to the client. The client (10) displays the execution result returned from the server (20). More specifically, when the processing type is search, the server (20) reads the specified file by the file reading unit (26), executes the search with the search condition specified by the processing unit (27), and searches. The result is converted to HTML by the HTML conversion unit (28), sent back to the client (10), and displayed. When the processing type is added or changed, the input screen generation unit (29) stores data corresponding to the file. An addition screen or a data change screen is generated and sent to the client (10) for display. When addition or change is performed on the client based on this screen, the added data or changed data is sent to the server ( 20) to update the corresponding file in the directory / file storage unit (23) of the server (20).
[0009]
The server (20) according to the present invention includes a first means for analyzing the URL from the client (10), and a display / update button (the button) when the URL from the client instructs to display the initial screen. And a second means (initial screen generation unit 22) for generating and returning an initial screen including a function of automatically adding that to the URL when the is selected, and a URL from the client (10) Is instructing a file display / update request, the file list (the function to automatically add the selected file name and specific extension to the URL and the processing type when the processing type is input) A third means (file list generation unit 24) for generating a processing type automatically added to the URL after the file name and a specific extension and returning the processing type to the client; 4th means for reading a file corresponding to the file name and returning it to the client when the URL from the client (10) includes a file having a specific extension, and the URL from the client (10) When a processing type (for example, search / search condition) is added in addition to the file name with the extension of, the file is read, the process is executed based on the processing type, and the execution result is It has the 5th means (the file reading part 26, the process part 27, and the HTML conversion part 28) returned to a client. Further, when the processing type is data addition or data change, an input screen is generated (input screen generation unit 29) and sent to the client (10) when the data addition screen or data change screen corresponding to the file is received. And it has the 6th means which updates the content of the file corresponding when the data added or changed based on this screen is received from the client (10).
[0010]
The recording medium according to the present invention has a display / update button (a function that automatically adds a message to the URL when the button is selected) when the URL from the client instructs the display of the initial screen. If the first procedure for generating and returning the initial screen including the file and the URL from the client indicates a request to display / update the file, at least the file list (selected file name and identification) And a function for automatically adding the extension to the URL and a function for automatically adding the process type to the URL after the file name and specific extension when the process type is input). When the second procedure for returning to the client and the URL from the client include a file having a specific extension, the file corresponding to the file name is read and the class is read. If the processing type is added to the third procedure returned to the ant and the URL from the client in addition to the file name with a specific extension, the file is read and the added processing type The fourth procedure for executing the process based on the above and returning the execution result to the client is recorded as a program.
[0011]
DETAILED DESCRIPTION OF THE INVENTION

[0013]
2 (steps S1 to S10), FIG. 3 (steps S11 to S18), FIG. 4 (steps S20 to S24), and FIG. 5 (steps S30 to S33) are flowcharts for explaining the processing in the present invention. .
Hereinafter, an example of the operation of the present invention will be described with reference to FIGS.
(A) <Figure 2>
(Step S1) The server URL (in this embodiment, http: // lightning / Nmisdata) is input from the WWW browser of the client 10.
(Step S2) The server (20 in this embodiment) that receives the input URL via the Internet 30 generates an initial screen (menu screen: HTML format) by the initial screen generation unit 22 and sends it to the client 10. Return it.
[0014]
(Step S <b> 3) The client 10 displays the initial screen sent from the server 20. An example of the initial screen at this time is shown in FIG. As shown in the figure, the initial screen of this embodiment includes a display / update button for requesting display and update of file data, a script execution button for requesting execution of a script, a download button for downloading a server file to the client, There are provided an upload button for uploading a client file to the server, an administrator button used when making detailed settings of the server, a button such as.
[0015]
(Step S4) Here, first, the case where the display / update button is selected from the initial screen will be described.
(Step S <b> 5) Upon receiving the display / update request via the Internet 30, the server 20 generates a file list (HTML) by the file list generation unit 24 and returns it to the client 10.
[0016]
(Step S6) The client 10 receives and displays a file list. An example of the file list displayed at this time is shown in FIG. In the example of FIG. 7, a menu for arranging file names in a desired method (for example, ascending order) is also provided.
(Step S7) Directory information is embedded in the underlined file name of the file list screen of the present invention, and when the file name is selected, a function (program) for adding a file name after the URL is provided. ing. Therefore, for example, if sales data is selected by clicking the mouse from the file list, “sales data.DMX” is added to the URL (http: // lightning / Nmisdata) and sent to the Internet 30. Here, the extension “DMX” is an example of one specific extension that is determined in advance, and is not limited thereto.
[0017]
(Step S8) The file reading unit 26 of the server 20 that has received the URL to which the file name of the specific extension DMX (if there is no command part) is added, stores the file (table database) specified by the file name in the directory / Read from the file storage unit 23, convert to HTML and return to the client 10 (HTML conversion unit 28).
(Step S9) The client 10 displays the returned file. FIG. 8 shows an example of the contents screen of the sales data file at this time. In the present embodiment, buttons for specifying search, rearrangement, line addition, line change, download, and the like are provided for the displayed file.
(Step S <b> 10) When a search, add row, or change row button is clicked, a corresponding command part is added to the URL and sent to the server 20. When the download button is clicked, a window having selection items such as “Open” and “Save to disk” is displayed on the file content screen (see FIG. 9), and “Save to disk” is displayed from this window. When "" is selected, the file is saved on a hard disk or the like.
[0018]
(B) <Fig. 3>
(Step S11) In the server 20, the URL is analyzed by the URL analysis unit 21 ′, and when there is no specific extension (for example, DMX) (step S12: N), processing of a normal WWW server is performed (step S13). .
(Step S14) If there is a specific extension (for example, DMX), next, it is checked whether or not the file exists in the specified directory. If not, an error message is sent to the client 10 and displayed on the browser. (Steps S15 and S16).
(Step S17) If there is a designated file, it is checked whether there is an instruction part next, and processing corresponding to the instruction part, for example, processing after step S20 in FIG. 4, or processing after step S30 in FIG. (Step S18). If there is no command part, the process of step S8 is performed.
[0019]
(A) When the instruction part is a search <FIG. 4>.
(Step S <b> 20) The server 20 generates a search screen (HTML) by the search screen generation unit 25 and returns it to the client 10. At this time, the search screen displayed on the client 10 can specify parameters such as search items, comparison items, and comparison conditions.
[0020]
(Step S21) Now, it is assumed that “district” (column 3) is designated as a search item and character string designation “5” is designated as a comparison item. An example of the screen at this time is shown in FIG. By this designation, the search condition (parameter) designated here is newly added after the URL file name and sent to the Internet 30.
[0021]
(Step S22) The server 20 that has received this performs the same processing as Steps S12 to S18. However, if there are further search conditions after the command part (search) of the URL, this search is performed on the designated file in Step S23. A search is executed under conditions, and the result is converted into an HTML format by the HTML conversion unit 28 and returned to the client 10.
(Step S24) The client 10 displays the search result. FIG. 11 shows an example of a search result when searching in the “district 5” described above.
[0022]
(B) When the instruction part is input (adding line, changing line) <FIG. 5>.
(Step S30) The server 20 generates an input screen corresponding to the designated file (table database) by the input screen generation unit 29. That is, an input screen (table) that matches the length of each item in the file (table database) is generated. The generated input screen is returned to the client 10 in HTML.
(Step S31) An input screen is displayed on the client 10.
(Step S32) A desired input is performed on the displayed input screen on the browser. An input image at this time is shown in FIG. FIG. 5A shows an example of image data of currently registered file data. (B) is an example of an input image of data to be added. An input blank (input edit box) is displayed for each input item, and desired data is input into this blank. (C) is a display of registered file data that has been input and should be changed, and the contents of the data are changed by overwriting the file data. The data added or changed in this way is passed (submitted) to the server 20 via the Internet 30 by clicking the [OK] button or the like on the input screen.
[0023]
(Step S33) The server 20 updates the file based on the input (addition, change) data contents.
In order to cope with the addition or change of a plurality of lines, operability is improved by sending the next input screen from the server 10 to the client 10 in the HTNL format.
[0024]
In the above description, the server processing is shown in chronological order according to the present embodiment. However, in the server, the URL is analyzed by the URL analysis unit, and depending on the contents, for example, whether there is a file name or the file name The processing to be performed is determined depending on whether the extension is a specific one (DMX in the above embodiment), whether there is an instruction part, the type of instruction part, and parameters (search conditions, etc.). As described above, since the server 20 in this embodiment determines the process based on the URL, it is possible to cause the server to execute a desired process by directly specifying the content of the URL. For example, in the above example, as a step before selecting “change line”, “search” is executed to specify in advance the line to be changed, and then “change line” is selected to display the specified line. Can be changed.
[0025]
In the above embodiment, in steps S6 to S9, a file name is first selected from the file list, and the entire contents of the file are transferred to the client for display, and then search, rearrangement, line addition, line change, and download are performed. However, according to this method, the load increases when the amount of data in the file is large. If the file name, process name, and parameters thereof are known in advance, the file name, process name, parameters (conditions), etc. can be input immediately, so that the processing can be performed from step 11 at the server. Only the result (for example, the search result) needs to be captured in the client 10 (there is no need to capture the entire file before processing), and the load can be greatly reduced.
[0026]
In addition, once a process such as search is designated and a search / search condition is added to the URL, if the URL is registered as a bookmark (favorite), the above step can be performed by selecting the URL as necessary. Since the processing from S11 can be executed immediately, it is possible to always obtain a processing result such as a search using the latest file data. In addition, by inputting and specifying a predetermined URL, it is possible to move to a desired step from the client to the server among the above steps, and to return to the previous screen or move to the subsequent screen on the WWW browser, The convenience of the C / S system can be improved.
[0027]
In the above embodiment, search, input (line addition, line change) and the like have been described. However, if the processing unit 27 is provided with functions such as sorting, graphing, and aggregation, these various processes are also possible. Needless to say.
[0028]
The present embodiment can be used with any hardware as long as there is an Internet WWW browser and any OS (operating system). Therefore, the present invention is not limited to the specific hardware and OS determined. For example, any PC (personal computer), Internet TV, portable terminal, UNIX system, etc. may be used as long as it has a WWW browser. Further, since the program is sent from the server side to the client side, it is not necessary to install software in advance on the client side. The user can look at the file list and view the contents just by clicking on the desired file with the mouse. In addition, if the user knows the file name, the user can create a URL by himself / herself and can refer to it directly.
[0029]
In addition, when you use the marking function of the WWW browser and search or sort under the specified conditions, you can use the marking function to perform the same conditions ( For example, data processed with the same file name, the same search condition, the same sort condition, the same product name, etc.) can be obtained immediately. In addition, because it uses the Internet, it has the effect of making it easy to use telephone bills from around the world.
[0030]
Note that each processing procedure performed in the server as described above, that is, when the URL from the client instructs to display the initial screen, the display / update button (automatically when the button is selected) A first procedure for generating and returning an initial screen including a function to add a message to the URL, and when the URL from the client indicates a file display / update request, at least the file list (A function for automatically adding a selected file name and a specific extension to the URL, and when a process type is input, the process type is automatically added to the URL after the file name and the specific extension. The second procedure for generating the file and returning it to the client, and when the URL from the client includes a file having a specific extension, The third procedure for reading the file corresponding to the file name and returning it to the client, and the URL from the client when the processing type is added in addition to the file name with the specific extension added. Is read out and executed based on the added processing type, and the fourth procedure for returning the execution result to the client is converted into a program code and recorded on a recording medium such as a CD-ROM, and distributed to the market. The user can easily implement the file processing method and apparatus characterized by the present invention by installing the processing procedure recorded in the recording medium in the server computer.
[0031]
【The invention's effect】
According to the present invention, there is no need to newly create a special program, and the processing can be performed on the server simply by specifying various processing (search, input, etc.) by selecting and inputting items on the screen from a general-purpose browser. Can be executed, the execution result can be displayed on the client, and new data can be input (added, changed, etc.) to the file.
