When a processing type is input, the processing type is automatically added to the URL after the file name and the specific extension (the function is automatically added to the URL), and the generated processing type is returned to the client (file list generation unit 24). The client (10) adds one file name and a specific extension selected from the displayed file list to the URL and sends the URL to the Internet (30), or transmits the selected file from the file list. In addition to the three files and the specific extension, a processing type (search, addition, update, etc.) is added to the URL and transmitted to the Internet (30). If the processing type is search, a search condition (parameter) is added.

In the server (20), when only a file name with a specific extension added to the URL is added, the file is read and sent to the client (10), and the URL is added with the specific extension. If a processing type is added to the file name in addition to the file name, the processing is executed based on the processing 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 specified search condition in the processing unit (27), and executes the search. The result is converted to HTML by the HTML conversion unit (28),
0) and displays it. If the processing type is addition or change, the input screen generation unit (29) generates a data addition screen or data change screen corresponding to the file and sends it to the client (10). When the client performs addition or change based on this screen, the added or changed data is displayed on the server (2).

Thus, the present invention described in detail below can be realized.

FIG. 2 (Steps S1 to S10), FIG. 3 (Steps S11 to S18), FIG. 4 (Steps S20 to S2)
4) and FIG. 5 (steps S30 to S33) are flowcharts for explaining the processing in the present invention. Hereinafter, an operation example of the present invention will be described with reference to FIGS. (A) <FIG. 2> (Step S1) From the WWW browser of the client 10 to the URL of the server (in this embodiment, http: // lightning / N
misdata). (Step S2) Enter the entered URL on the Internet 3.
The server (20 in the present embodiment) received through “0” generates an initial screen (menu screen: HTML format) by the initial screen generation unit 22 and returns it to the client 10.

(Step S3) In the client 10,
The initial screen sent from the server 20 is displayed. FIG. 6 shows an example of the initial screen at this time. As shown in the figure, the initial screen of the present embodiment includes a display / update button for requesting display or update of file data, a script execution button for requesting execution of a script, a download button for downloading a server file to a client, Buttons such as an upload button for uploading a client file to the server, an administrator button used when performing detailed server settings, and the like are provided.

(Step S4) First, a case where the display / update button is selected from the initial screen will be described. (Step S5) Display / update request is sent to Internet 30
The server 20 receives the file list (HTML) by the file list generation unit 24 and returns it to the client 10.

(Step S6) The client 10 receives and displays the file list. FIG. 7 shows an example of the file list displayed at this time. In the example of FIG. 7, a menu for arranging the file names in a desired manner (for example, in ascending order) is also provided. (Step S7) The directory information is embedded in the underlined file name on the file list screen of the present invention, and when the file name is selected, a function (program) for adding the file name after the URL is provided. ing. Therefore, for example, if the sales data is selected from the file list by clicking the mouse, the URL (ht
tp: // lightning / Nmisdata) followed by "Sales Data.DM
"X" is added and transmitted to the Internet 30. Here, the extension “DMX” is an example of one predetermined specific extension, and is not limited to this.

(Step S8) The file reading unit 26 of the server 20, which has received the URL to which the file name of the specific extension DMX (when there is no command part), is added to the file (table database). ) Is read from the directory / file storage unit 23, converted into HTML, and returned to the client 10 (HTML conversion unit 2).
8). (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 this embodiment, buttons are provided for designating search, sorting, line addition, line change, download, and the like for the displayed file. (Step S10) When a search, line addition, or line change button is clicked, a corresponding instruction unit 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). From this window, “save to disk” is displayed. Is selected, save the file to a hard disk or the like.

(B) <FIG. 3> (Step S11) In the server 20, the URL analysis unit 2
Parse the URL with 1 'and use a specific extension (eg DMX)
If there is no (Step S12: N), the processing of the normal WWW server is performed (Step S13). (Step S14) If there is a specific extension (for example, DMX), it is checked whether or not the file exists in the designated directory. If not, an error message is sent to the client 10 and displayed on the browser. (Step S
15, S16). (Step S17) If there is a designated file, it is determined whether there is an instruction section next, and processing corresponding to the instruction section, for example, processing after step S20 in FIG. 4 or step S3 in FIG.
The process after 0 is executed (step S18). If there is no command section, the process of step S8 is performed.

(A) When the instruction part is a search <FIG. 4>. (Step S20) The server 20 searches the search screen generation unit 25
Generates a search screen (HTML) and returns it to the client 10. At this time, the search screen displayed on the client 10 can specify parameters such as a search item, a comparison item, and a comparison condition.

(Step S21) Now, it is assumed that “district” (column 3) is specified as a search item, and a character string specification “5” is specified as a comparison item. FIG. 10 shows an example of the screen at this time. With this designation, the search condition (parameter) newly specified here is added after the file name of the URL and transmitted to the Internet 30.

(Step S22) Server 2 receiving this
In step S23, the same processing as in steps S12 to S18 is performed. However, if there is another search condition after the URL instruction part (search), a search is performed on the specified file in step S23 with this search condition. 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 the search is performed in “area 5” described above.

(B) When the instruction section is input (line addition, line change) <FIG. 5>. (Step S30) In the server 20, the input screen generation unit 29 generates an input screen corresponding to the specified file (table database). That is, an input screen (table) corresponding to the length of each item of 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 made on the displayed input screen on the browser. FIG. 12 shows an input image at this time. FIG. 7A is an example of an image of currently registered file data. FIG. 2B shows an example of an input image of data to be added. An input blank box (input edit box) is displayed for each input item, and desired data is input in this blank box. FIG. 11C shows the registered file data that has been input and that is to be changed, and the data content is 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 an [OK] button or the like on the input screen.

(Step S33) The server 20 updates the file based on the input (added, changed) data contents. The operability is improved by transmitting the next input screen from the server 10 to the client 10 in the HTNL format in order to cope with the addition or change of a plurality of lines.

In the above description, the processing of the server 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 not. The type of processing is determined depending on whether the extension of the file name is a specific one (DMX in the above embodiment), whether there is an instruction part, the type of the instruction part, and whether there is a parameter (such as a search condition). . in this way,
Since the server 20 according to the present 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, a line to be changed is specified in advance by executing “search” as a step before selecting “line change”, and then “line change” is selected to display the specified line. Can be changed.

In the above embodiment, steps S6 to S6
At 9, a file name is first selected from a file list, the entire contents of the file are transferred to the client and displayed, and then search, rearrangement, line addition, line change, download and parameters are specified. However, according to this method, when the data amount of the file is large, the load increases. If the file name, the processing name and its parameters are known in advance, the processing can be performed immediately from step 11 by inputting the file name, the processing name, the parameters (conditions), and the like. Only the results (for example, search results) need to be imported to the client 10 (there is no need to import the entire file before processing), and the load can be greatly reduced.

It should be noted that once a process such as a search is designated,
When a search / search condition is added to the RL, if the URL is registered as a bookmark (favorite), the process from step S11 can be executed immediately by selecting this URL as needed. Therefore, it is possible to always obtain a processing result such as a search using the latest file data. Further, by inputting and specifying a predetermined URL, it is possible to shift to a desired step from the client to the server among the above steps,
In addition, it is possible to return to the previous screen or move to the rear screen on the WWW browser, thereby improving the convenience of the C / S system.

In the above embodiment, search, input (line addition, line change) and the like have been described.
It is needless to say that if various functions such as sorting, graphing, totaling, and the like are provided in 7, the various kinds of processing can be performed.

In this embodiment, if there is an Internet WWW browser, any hardware, any OS
(Operating system) can be used. Therefore, the present invention is not limited to the specified specific hardware and OS. For example, any PC (personal computer), Internet TV, portable terminal, UNIX system, etc. may be used as long as it has a WWW browser. In addition, since the program is sent from the server to the client, it is not necessary to install any software on the client in advance. The user looks at the file list,
Just click on the file you want to view with a mouse and you can see its contents. Also, if the user knows the file name, the user can create the URL by himself and can directly refer to the URL.

Further, when a search or sort is performed under a predetermined condition by using a marking function of a WWW browser, the marking function is used to repeat the operation from the beginning and to compare the latest data with the previous data. Data processed under the same conditions (for example, the same file name, the same search condition, the same sort condition, the same product name, etc.) can be immediately obtained. In addition, the use of the Internet has the effect of making it easy to use telephone bills from all over the world.

Each processing procedure performed in the server as described above, that is, the URL from the client
Generates and returns an initial screen including a display / update button (has a function of automatically adding that to the URL when the button is selected) when the user instructs to display the initial screen. First procedure and URL from client
Is instructed to display / update the file, at least a file list (a function to automatically add the selected file name and a specific extension to the URL, and a case where the processing type is input) A second procedure of generating the processing type and automatically adding the URL to the URL after the file name and the specific extension) and returning the URL to the client; and When a file is included, a third procedure of reading out the file corresponding to the file name and returning it to the client, and the URL from the client is such that the processing type is added in addition to the file name to which a specific extension is added. Program, a fourth procedure of reading the file, executing the processing based on the added processing type, and returning the execution result to the client is performed. By encoding and recording the information on a recording medium such as a CD-ROM, it can be distributed to the market, and the user can easily install the processing procedure recorded on the recording medium in a server computer to obtain the features of the present invention. And a file processing method and apparatus.

[0031]

According to the present invention, there is no need to create a new special program, and only a variety of processes (search, input, etc.) are specified by selecting and inputting items on the screen from a general-purpose browser. To let the server do that,
It becomes possible to display the execution result on the client and to input (add, change, etc.) new data to the file.
