Description

  The present invention relates to an information providing apparatus and the like, and more particularly to an information providing apparatus that refers to a database in response to a request from an information terminal and returns data corresponding to the request to the information terminal.

  In recent years, an increase in information on the Internet has accelerated, and information providing methods linked to databases are becoming common. The provision of information in cooperation with the database is performed as follows, for example. That is, when a user using the personal computer 1202 shown in FIG. 12 searches for information corresponding to a predetermined search condition, the information providing server 1201 is accessed via the Internet 1203. At this time, the user notifies the information providing server 1201 of the search condition, for example, by inputting a keyword or the like as the search condition in a predetermined form provided by the information providing server 1201.

  The search condition is received by the transmission / reception means 1207 constituting the information providing server 1201 and passed to the search means 1205. Here, the search means 1205 is provided by a program executed by a CPU (central processing unit) constituting the information providing server 1201, and a work memory 1206 described later is a RAM (Random Access) controlled by the program. Memory). In general, the above program is provided by CGI (Common Gateway Interface), and an example thereof is shown as search.cgi 1300 in FIG. The search condition is given as an argument of search.cgi 1300.

  When the search unit 1205 receives the search condition, the search unit 1205 acquires data corresponding to the search condition from the database 1204 and temporarily stores the data in the work memory 1206. Subsequently, the search means 1205 inputs the corresponding data into variables in the search.cgi 1300, and outputs line by line as a html (HyperText Markup Language) format file with a print command. That is, the output content 1302 of the print command 1301 shown in FIG. 13 is described in a format including a variable. By inputting the data corresponding to the variable, the html format data including the acquired data is input each time. It is generated and transmitted as display data. The portion other than the variable in the output content 1302 becomes the basis of the display data, and the format of the display data on the browser, that is, the design is determined by the portion. FIG. 14 shows an example of display data. It can be seen that predetermined data or the like is stored in the variable portion of the output content 1302 to constitute display data (searchresult.html) 1401.

  Through the above operation, display data in html format including data corresponding to the search condition is created and transmitted to the personal computer 1202 each time. As a result, the personal computer 1202 can refer to data matching the search condition in a predetermined format.

  In the operation described above, the format is described in the program provided as the search means. Therefore, when changing the format of the display data, it is necessary to rewrite search.cgi itself in the above example.

  However, the rewriting requires knowledge of a description rule when describing the design of display data in html. In addition, since knowledge of programming is required, there arises a problem that no one can easily change the format.

  In addition, when a plurality of formats are required, a plurality of programs are required, or descriptions corresponding to a plurality of programs need to be made in one program, which causes a problem that the program itself is enlarged.

  Furthermore, since the program is accompanied by bugs, and the bugs put a load on the server, the reliability of the system itself is reduced. Therefore, a program that is rewritten by the user and cannot be confirmed to operate normally can be easily executed. There is a problem that it must be avoided as much as possible.

  In addition, in order to rewrite and register a program, very high management authority is required on the information providing server, but it can be said that giving such authority to all users is a source of trouble.

  The present invention has been proposed based on the above-described conventional circumstances, and there is no risk based on the change because there is no need to change the program, and an information providing device that can easily change the format of the display data is provided. The purpose is to do.

  The present invention employs the following means in order to achieve the above object. That is, the present invention is premised on an information providing apparatus that acquires data corresponding to a request from an information terminal from a database, converts the data to display data corresponding to a predetermined format, and transmits the display data to the information terminal.

Here, the format decomposing means indicated start position and end position of the structural unit each time the structural units that constitute the format, a format basic data attached parts information described as a comment statement, its component information Based on the starting position and the ending position shown, it is broken down into structural units and stored in the format storage means constituting the format database.

Next, the format acquisition means receives the search condition from the information terminal, and acquires each structural unit corresponding to this search from the format storage means. The display data generation unit generates the display data by inputting the search result data acquired from the database into the variable of the structural unit acquired by the format acquisition unit. The generated display data is transmitted to the information terminal by the transmission means. Further, the format disassembling means includes the format including the type of the structural unit corresponding to the part information and the command to be executed when using the structural unit corresponding to the part information included in the part information. The display data generation unit determines the type of the structural unit, stores the data in the storage unit, associates the data acquired from the database with the structural unit only for the predetermined type , and further acquires another structural unit. by binding to generate display data and.
In this way, since the format decomposition means decomposes, analyzes, and registers the format based on the component information attached to the format basic data, the program is understood if only the definition of the component information attached as a comment is understood. Even basic users can easily register basic format data. In addition, by acquiring a predetermined format from the format database and inputting data into the variable as necessary, if the correspondence between the variable and the data acquired from the database is determined, the processing content in the display data generating means, That is, the program does not need to be changed thereafter. In addition, since the program that generates the display data can be configured only by combining text and inputting data to variables, it can be applied to various formats with a simple configuration, and the program may be enlarged. Absent. In addition, since it is not necessary to change the program, it is possible to prevent an abnormal operation of the program in advance, and as a result, the reliability of the system is improved. Furthermore, since a user can easily register a format if he / she has the authority to use even a format decomposition device, he / she does not have to have a strong authority such as the authority to change a program as in the past. It leads to improvement. Further, since the display data generation means can determine the existence of a variable to which data should be input only by determining the type of the structural unit, it is not necessary to analyze the presence or absence of the variable in the structural unit. That is, since it is not necessary to analyze the description content of the structural unit, the data input process can be completed at high speed.

  In addition, the number of data obtained from the database in response to a request from the information terminal is determined, and a number determination unit that selects a structural unit to be used based on the number of cases is provided. There is a configuration for acquiring the determined structural unit.

  Note that the number determination unit may select different structural units for the case where the number of acquired data is one or more and less than the predetermined number and the case where the number is greater than the predetermined number.

  According to this configuration, by dynamically changing the structural unit to be acquired based on the acquired number of data items, it is possible to provide a user with a display that can be easily viewed according to the number of cases. In the present invention, since the format can be registered for each structural unit, it is very effective because it is not necessary to prepare display data generation means, that is, a program for each format even when switching between a plurality of formats. is there.

  Further, the load of the CPU provided in the information providing device or the load in the network to which the information providing device is connected is determined, and a load determining unit that selects a structural unit to be used based on the load is provided. The configuration unit determined by the load determination unit may be acquired.

  In this configuration, by dynamically changing the format according to the load on the CPU or the network, it is possible to avoid the use of the high load format and prevent the system performance from being lowered at the time of high load.

  Furthermore, the information providing apparatus according to the present invention further includes transmission means for transmitting the input data for causing the information terminal to select the structural unit and / or the display order of the structural unit, and the format acquisition means is configured to respond to the input data. It is good also as a structure which acquires each structural unit from a format memory | storage means based on a selection result.

  In this configuration, the format acquisition unit acquires each structural unit based on the design selected by the user, so that display data having different display contents can be easily acquired. At this time, a program having a plurality of or complicated descriptions is not required.

  Further, the format acquisition means may be configured to acquire predetermined respective structural units from the format storage means based on information obtained by communication with the information terminal, or authentication information of a user who uses the information terminal.

  In this case, the design of the display data can be changed dynamically and easily without any user instruction.

  The format disassembling means is configured to decompose the command to be executed when using the structural unit corresponding to the part information included in the part information, and store the command in the format storage means. The command executing means may be configured to execute the command when the constituent unit acquired by the format acquiring means is used when the constituent unit is used.

  As an example of the command, there is a command for limiting a condition when using a structural unit, and an example of including a condition information which is the limiting condition is described. In this case, the use condition determining means (an example of the command execution means) includes condition information, information on the information terminal (IP address, MAC address, etc.) or information on the user who uses the information terminal (user ID, user name, etc.) Based on the above, it is determined whether or not the structural unit can be used. Then, the display data generating means generates display data based on the determination result by the use condition determining means.

  As a result, it is possible to restrict usage for each structural unit. As a result, it is possible to minimize registration of structural units while maintaining necessary security. In addition, since the use restriction can be performed only by describing in the format basic data, the format registration user can easily restrict the use of the structural unit without performing the application / registration process.

  Another example of the command is a command indicating that another structural unit should be inserted when the structural unit is used. The command execution means acquires another structural unit from the format storage means based on the command indicating that it should be inserted, and inserts it at the corresponding location.

  As a result, the format registration user can easily reuse the already registered structural unit.

  Here, the information providing apparatus and the format decomposing apparatus can be embodied using a computer. In that case, each means mentioned above is actualized by operating a program on a computer.

Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings for understanding of the present invention. In addition, the following embodiment is an example which actualized this invention, Comprising: It is not the thing of the character which limits the technical scope of this invention. In the following embodiments, CGI is used as search means and HTML is used as display data. However, the program language is not limited, and the display data is based on ML (Markup Language). Good.
(Embodiment 1)
Hereinafter, the information provision apparatus in Embodiment 1 which concerns on this invention is demonstrated.

  FIG. 1 is a schematic functional block diagram in the case where the information providing apparatus 100 includes an information providing server 101 and a format decomposition apparatus 110. That is, in other words, the present invention may be configured by the information providing server 101 and the format decomposition device 110.

  The information providing server 101 and the format decomposition device 110 are communicably connected to the personal computer 102 via a network such as the Internet 103.

  FIG. 2 is a schematic configuration diagram of the information providing server 101 and the format decomposition device 110. The CPU (Central Processing Unit) 201, the RAM (Random Access Memory) 202, the ROM (Read Only Memory) 203, the HDD ( Hard Disk Drive) 204 and a network interface 205 are connected via an internal bus 206. The CPU 201 executes a program stored in the ROM 203, the HDD 204, or the like by using the RAM 202 as a work area, for example, and each means writes and reads data to and from the format database 113 and the database 104. By doing so, it functions as the search means 105 and the format decomposition means 112 shown in FIG. The network interface 205 is connected to the Internet 103 and can exchange data with an external terminal (such as the personal computer 102).

  First, the processing of the format decomposition apparatus 110 will be described. As shown in FIG. 4, the format 401 used in the present embodiment is described in HTML that can be used in a conventionally used browser. The format 401 can be read and displayed by the browser without changing the portion of the variable (for example, the variable 420) surrounded by “%%”. Although there is a limitation on the display on the drawing, the contents of the format 401 are partially deleted, but when displayed on the browser, the display 601 in FIG. 6 is obtained. A variable display portion 602 in the display 601 in FIG. 6 corresponds to the variable 420 described above.

  The format 401 can be created on the personal computer 102 using homepage creation software, for example. However, in the format 401, component information 402 to 411 is attached to the start position and the end position of the structural unit for each predetermined structural unit. Since the component information 402 to 411 is described as a comment sentence, there is no influence at the time of display by the browser. Moreover, although the said component information is judged as a start position and an end position in the order which came out from the head of the file, you may describe that it is a start position and an end position in a comment. Hereinafter, the format 401 with the component information is referred to as format basic data.

  The format basic data created on the personal computer 102 is transmitted to the format decomposition apparatus 110 by a format registration user using, for example, FTP (File Transfer Protocol) or HTTP (HyperText Transfer Protocol). Here, for example, after authenticating the user who transferred the format basic data, the format decomposition apparatus 110 receives the format basic data if there is no problem (FIG. 3: S301).

  Subsequently, in the format decomposition apparatus 110, when the transmission / reception means 111 receives the format basic data, it transmits the format basic data to the format decomposition means 112. When receiving the basic data, the format decomposing means 112 first reads data for one line from the beginning of the file (FIG. 3: S302). The data read first is the component information 402 in FIG. Next, the format decomposing means 112 determines whether the read data is a part information starting part (FIG. 3: S303).

  Here, since the data on the first line is the component information start part, another line is read (FIG. 3: S303 Yes → S304). Further, it is determined whether the read data is a part information end part. In this case, since it is not a component information determination unit, the read data is temporarily stored in the memory (No in S305 → S306). By repeating the above-described processing from S304 to S306 a plurality of times, the text described in the range 430 in FIG. 4 is stored in the memory.

  Next, one line corresponding to the part information 403 is read, and if it is determined in step S305 that the part information end unit is obtained, the memory content saved in the process S306 is analyzed and stored in the format database 113 ( FIG. 3: S305 Yes → S307 → S308).

  The memory content analysis process S307 is shown as follows.

  First, “No.” that can uniquely determine the format basic data is determined for the read format basic data. Here, if the format is read first, it is determined to be “001”, for example. However, for example, a name given as an argument at the time of transmission of the format basic data may be set as the “No.”.

  Next, the contents described in the part information start part are determined and stored in “id0” of the format database 113 described later. Here, <!-Part: 1-> is described in the part information start part. For example, Part: 1 is defined in advance as "Description not directly related to display contents". Suppose that it is. The meaning of the contents described in the component information may be freely defined. Here, it is assumed that “1: description that is not directly related to display contents”, “2: description that is directly related to display but does not include a variable”, and “3: description that is directly related to display and includes a variable”.

  Further, a number is assigned as “id1” for each structural unit constituting the basic format data. Here, since it is the first structural unit, “0” is added.

  Through the above process, the first structural unit constituting the format basic data is registered in the format database 113. A registration image is shown in FIG. That is, “001” is displayed in the “No.” item, “1” indicating that the “id0” item is not directly related to the display content, and “id1” is the first structural unit. “0” indicating the presence is stored, and the text in the range 430 is stored in the “TEXT” item.

  The format database corresponding to the format (format basic data) 401 shown in FIG. 5 is determined by determining the end of the format basic data file after registration in the format database, and by repeating the process of reading the next line if it is not completed. 501 is completed (FIG. 3: S309 No → S302).

  In the determination of the end of the file of the format basic data, when it is determined that the file is ended, the registration of the format basic data in the format database 113 by the format decomposing means 112 is completed (FIG. 3: S309 Yes → End).

  As described above, since the format decomposition means decomposes, analyzes, and registers the format based on the component information attached to the basic format data, it understands the program as long as it understands the definition of the component information attached as a comment. Even basic users can easily register basic format data.

  Next, a method for using the registered format basic data will be described. First, a user who wants to search for data accesses the information providing server 101 via the Internet 103 using, for example, the personal computer 102. Naturally, the personal computer 102 does not have to be a personal computer that has transmitted the format basic data to the format decomposition apparatus 110.

  When the personal computer 102 accesses the information providing server 101, for example, input data for inputting search conditions for information search is transmitted to the personal computer 102. When the personal computer 102 receives the input data described in HTML, the personal computer 102 displays it using a browser, inputs a search condition desired by the user into a predetermined location, and then presses a “search” button, for example. When the user presses the button, the search condition input by the user is transmitted to the search unit 105 via the transmission / reception unit 107.

  The search means 105 that has received the search condition acquires data corresponding to the search condition from the database 104. Since the acquisition of the data is a process that has been performed conventionally, the details are omitted. The acquired data is temporarily stored in the work memory 106 together with, for example, the number of cases (FIG. 7: S701 → S702).

  Subsequently, the format acquisition means 108 constituting the search means 105 accesses the format database 113 via the Internet 103, and uses, for example, “No.” as a key for the structural unit registered in the format database 113. Further, it is acquired in ascending order based on “id1” (FIG. 7: S703). The acquisition method is performed, for example, by issuing a SQL (Structured Query Language) statement, and the basic format data shown in FIG. Even when a plurality of format basic data are registered, only a predetermined structural unit can be acquired by using “No.” as a key. In addition, the “id0” item is also acquired.

  Next, the display data generation means 109 constituting the search means 105 combines them while determining “id0” in the order of acquisition. Here, since the acquired data does not have a variable unless the “id0” item is “3”, the “TEXT” item may be simply combined (FIG. 7: S704 No → S705).

  In addition, when the “id0” item of the acquired data is “3”, the “TEXT” item, which is the structural unit, includes a variable, and the data acquired from the database 104 using a predetermined process. Is input to the corresponding variable (FIG. 7: S706). The “TEXT” item in which data is input as a variable is also combined in the same manner as described above (FIG. 7: S706 → S705).

  As described above, since the display data generation means can determine the existence of a variable to which data should be input only by determining the type of the structural unit, it is not necessary to analyze the presence or absence of the variable in the structural unit, and the data can be It is possible to complete the input process.

  By repeating the combination of the “TEXT” items until the structural unit is completed, an HTML file in which data is input to the variable, that is, an HTML file in which the variable is input in the format 401 is created (FIG. 7: S707 Yes → End). Here, since the comment is not related to the display, the component information that is the comment may be deleted upon combining.

  The input of the corresponding data to the variable can be easily performed by the conventional programming process, and even when a plurality of data is acquired by retrieval, the number of acquired data is also acquired. Therefore, it suffices to perform loop processing in the programming process for the number of cases.

  The format 401 created by the processing by the display data generating means 109 and having data input as variables is transmitted to the personal computer 102 as display data. As a result, display data including data corresponding to the search condition is displayed on the browser operating on the personal computer 102.

  As described above, a predetermined format is obtained from the format database, and the display data generation means inputs data to the variable as necessary. Therefore, as long as the correspondence between the variables and the data acquired from the database is determined, the processing content in the display data generating means, that is, the program does not need to be changed thereafter.

  In addition, since the program that generates the display data can be configured only by combining text and inputting data to variables, it can be applied to various formats with a simple configuration, and the program may be enlarged. Absent. In addition, since it is not necessary to change the program, it is possible to prevent an abnormal operation of the program in advance, and as a result, the reliability of the system is improved.

  Furthermore, since the format can be registered by the format decomposing apparatus, the user who provides data by the database can easily change the format without knowledge of the program as long as the display data can be designed. In other words, the design work and the programming work can be performed in parallel by another person, so that work efficiency can be improved.

  Furthermore, since the user can easily register a format if he / she has the authority to use the format decomposition device, he / she does not need to have a strong authority such as the authority to change the program as in the past, resulting in the reliability of the system. Leads to improvement.

In the above embodiment, the component information is always attached to the start position and the end position of each structural unit. For example, id0 is automatically set to “1” for a structural unit to which no component information is attached. It is good also as storing in a format database, and you may decide not to store the structural unit to which component information is not attached | subjected, or the structural unit defined as the storage unnecessary by component information.
(Embodiment 2)
Subsequently, Embodiment 2 of the present invention will be described. In the second embodiment, the description of the same processing / configuration as in the first embodiment is omitted.

  FIG. 8 shows two HTML files 801 and 811, each having a different structural unit. However, the structural unit A802 and the structural unit A812 have the same content (design), and the structural unit C804 and the structural unit C814 have the same content. The structural unit B 803, the structural unit F 807, the structural unit D 815, and the structural unit E 816 have different contents. In the case where HTML files 801 and 811 having similar structures but different overall contents are provided to the user, the conventional technique requires a program corresponding to the two designs. 2 easily realizes the difference between the two displays.

  First, when the personal computer 102 accesses the information providing server 101, for example, input data for inputting a search condition for information search is transmitted to the personal computer 102. Here, it is assumed that the input data is provided with a search condition input field 902 and a design selection field 903 as shown in the input data 901 of FIG.

  For the input data 901, the user inputs a search condition in the search condition input field 902, further selects a desired design from the design selection field 903, and presses the search button. Then, in addition to the search conditions described in the first embodiment, information on the selected design is also transmitted to the search means 105. Here, assuming that design Y (HTML file 811) is selected, for example, the selected content is transmitted in the state of “A, D, E, C” as an argument.

  The format acquisition means that has received the design information acquires each structural unit “A, D, E, C” in this order based on the argument when acquiring each structural unit from the format database 113. Naturally, when the design X is selected, “A, B, F, C” is obtained as an argument, and each structural unit is acquired based on this.

  Thereafter, display data of the design desired by the user is displayed on the personal computer 102 by performing the same processing as described in the first embodiment.

  As described above, the format acquisition unit acquires each constituent unit based on the design selected by the user, so that display data having different display contents can be easily acquired. At this time, a program having a plurality of or complicated descriptions is not required. That is, it is possible to deal with various formats by providing only one format acquisition unit 108 and display data generation unit 109.

  The structural units B803, F807, D815, and E816 all have different contents. However, even if they are the same, there is no problem, and each structural unit may or may not include a variable.

  In the above description, the structural unit “A, D, E, C” is used as an argument. However, “No.”, which is the format basic data management number of “Design Y”, is sent as an argument to the search means and designed. Y itself may be selected directly.

  In addition, the case described above is a case where the user voluntarily selects a format. For example, the format acquisition means determines the structural unit and the design type to be acquired based on information obtained through communication with a personal computer. Also good. Information obtained by communication includes, for example, an IP (Internet Protocol) address, a MAC (Media Access Control) address, information managed by a browser of the access source (in this case, the personal computer 102), and the like.

  For example, if a personal computer of Company A uses an IP address within a predetermined range, Design X is applied to access by a personal computer corresponding to the range of the IP address, and access other than that. On the other hand, the design Y is applied. Even in this case, a common format can be used in a place where there is no need to change.

  Further, in the case of providing information (data) that requires user authentication, a structural unit to be acquired may be determined based on the user authentication information.

  The information managed by the browser includes information that the browser can transmit to the information providing apparatus, such as the type and version of the browser. As an example of using information managed by the browser, there is a process of determining the browser type and applying the design Z for the mobile terminal for access from the browser in the mobile information terminal such as a mobile phone. In this case, it is possible to easily provide a special design for a mobile terminal that tends to have a particularly small display screen, and thus it can be said that the effect of the application of the present invention is high.

  As described above, the design of the display data can be changed dynamically and easily without a user instruction. This is particularly effective when, for example, the format database is used by a plurality of users (contractors).

The design may be selected at random.
(Embodiment 3)
Subsequently, Embodiment 3 of the present invention will be described. In the third embodiment, the description of the same processing / configuration as in the first and second embodiments is omitted.

  In the present embodiment, a configuration in which the search unit 105 further includes the number determination unit 114 will be described.

  In the first embodiment, the search means 105 that has received the search condition acquires the data corresponding to the search condition from the database 104, and the acquired data is temporarily stored in the work memory 106 together with the number of cases. (FIG. 7: S701 → S702).

  At this time, in the present embodiment, the number of acquired data is acquired by the number determination unit 114.

  Next, the number determination unit 114 that has acquired the number of data determines the number of cases. Specifically, there are a case where the number is 1 or more and less than a predetermined number, and a case where the number is a predetermined number or more. Hereinafter, the predetermined number will be described as four.

  FIG. 10 shows format A1001 and format B1011. Note that, in the two formats, the structural unit 1002 displaying “search results” and the structural unit 1004 describing “inquiry until ABC sales” are the same, and are displayed regardless of the number of cases. .

  Here, when the number of data is 6, for example, the number determination unit 114 notifies the format acquisition unit 108 that the structural unit 1003 indicating the summary display is selected.

  Upon receiving the notification, the format acquisition unit 108 acquires the structural unit 1003 from the format database 113 according to the notification. Then, the display data generating unit 109 creates display data by inputting corresponding data to the variable of the structural unit 1003.

  When the number of data is 3, for example, the number determination unit 114 notifies the format acquisition unit 108 that the structural unit 1005 indicating the detailed display is selected.

  Upon receiving the notification, the format acquisition unit 108 acquires the structural unit 1005 from the format database 113 according to the notification. Then, the display data generating unit 109 creates display data by inputting corresponding data to the variable of the structural unit 1003.

  Regardless of the number of cases, the structural unit 1002 and the structural unit 1004 are also acquired.

  As described above, by dynamically changing the structural unit to be acquired based on the acquired number of data items, it is possible to provide the user with a display that is easily viewable in a flexible manner according to the number of data items. Further, in the present invention, since the format can be registered for each structural unit, it is not necessary to prepare display data generating means, that is, a program for each format even when a plurality of formats are used. That is, the format can be easily changed.

  Here, instead of or in addition to the above-mentioned number determination means, a load determination means 117 may be provided. The load determination unit 117 determines the load on the CPU 201 and / or the network 103. Here, the load on the network 103 is determined by determining the amount of packets received or detected by the network I / F 205.

  The load determination unit 117 determines whether the load is equal to or greater than a predetermined threshold. Here, if the threshold is equal to or greater than the predetermined threshold, the structural unit 1003 (low load format) indicating the summary display is selected, and if it is less than the threshold, the structural unit 1005 (high load format) indicating the detailed display is selected. The high-load format mentioned here is a unit described in the present application, and includes a format that places a load on an information providing server (CPU) or a network because it includes, for example, image data or has a large amount of information. A low-load format is a format that does not apply a load, such as displaying only items.

As described above, by dynamically changing the format according to the load on the CPU or the network, it becomes possible to avoid the use of the high load format and prevent the system performance from being lowered at the time of high load. Naturally, since the low-load format and the high-load format are properly used, there is no problem that the user cannot obtain the search result as in the conventional “display indicating system busy”.
(Embodiment 4)
Subsequently, Embodiment 4 of the present invention will be described. In the fourth embodiment, the description of the same processes and configurations as those of the first, second, and third embodiments will be omitted.

  As one embodiment of the present invention, for example, a case where a plurality of companies use the same information providing server can be considered. Further, even within the same company, there are cases where it is desired to limit usable structural units for each department or for each user. In such a case, if the restriction is performed in units of format basic data, the use is restricted even in the case of a constitutional unit that may be shared. As a result, many identical constitutional units are required. turn into. In addition, for example, by reporting to the system administrator of the information providing server, if the system registers the availability of each unit, the management cost is increased and the basic format data can be easily registered. The problem that it is not possible arises. In order to solve such a problem, in the present embodiment, the search unit 105 further includes a use condition determination unit 115.

  Hereinafter, the setting for performing the use restriction and the processing of the use condition determining unit 115 will be described.

  First, the format registration user registers the format basic data for each constituent unit by transmitting the format basic data in which a predetermined command is inserted into the component information to the format decomposing means 112. An example when the component information of the format basic data is registered in the format database is shown in FIG. The part information 1103 in the structural unit 1102 of the format database 1101 describes “# ALLOW = YAMADA, 192.168.24.36, 00-99-26-69-5B-A4 #”. This description is a description that limits users who can use the structural unit. Here, the user is “YAMADA”, the personal computer (information terminal) whose IP address is “192.168.24.36”, or the MAC address is “ Only the personal computer “00-99-26-69-5B-A4” can be used. Here, “ALLOW” is a command that limits the users of each structural unit. Hereinafter, the limited description is referred to as condition information. The user constituting the condition information is the user at the time of authentication described in the first embodiment, and the IP address and MAC address are the addresses of the personal computer that is currently accessing.

  When the structural unit registered as described above is acquired by the format acquisition unit 108 as necessary, the use condition determination unit 115 reads the condition information. Subsequently, the user who has authenticated the personal computer 102 currently accessed, the IP address and the MAC address of the personal computer 102 are acquired, and it is determined whether or not the condition information is matched.

  Here, if they match, the user determines that the structural unit can be used, and notifies the display data generation means 109 to that effect. Upon receiving the notification, the display data generation unit 109 creates display data using the structural unit.

  If they do not match, the user determines that the structural unit cannot be used, and notifies the display data generation means 109 to that effect. Upon receiving the notification, the display data generation unit 109 does not display the display data or creates display data from which the structural unit is deleted.

  As described above, the use condition determining means determines the condition information for each structural unit, so that the usage can be restricted for each structural unit. As a result, it is possible to minimize registration of structural units while maintaining necessary security. In addition, since the use restriction can be performed only by describing in the format basic data, the format registration user can easily restrict the use of the structural unit without performing the application / registration process.

  Although the use restriction is performed by setting “ALLOW =” as described above, for example, a command (for example, DENY) that lists users who cannot use the service may be used. Further, it is not necessary to limit the usage restriction. For example, another command may be inserted into the component information, and the command execution unit 116 may execute processing corresponding to the command. In other words, the use condition determination unit is an example of a command execution unit.

  As an example of the command, there is a description “# INCLUDE = 001: 3: 3 #” as shown in the part information 1105 in the structural unit 1104 in FIG. As a result, the command execution means 116 places the structural unit in which “No.” = 001, “id0” = 3, “id1” = 3, that is, the structural unit 502 shown in FIG. You may make it insert in the location where is described.

  As described above, when the command execution unit executes a command for inserting a predetermined structural unit, the format registration user can easily reuse the already registered structural unit.

  The command includes a control variable for controlling the operation of the search means, the display data generation means, and the like (the variable here is not a variable for inputting data acquired from the database). That is, for example, by describing “# default-value = 6: 7: 8: 9 #” as a command, the control variable “default-value” used by each means is set to “6: 7: 8: 9”. It is also possible to use such as inputting.

  This also allows the format registration user to control the program without changing the program, thereby improving convenience.

  In addition, each Embodiment 1-4 described above can be utilized in combination, respectively.

  The information providing apparatus according to the present invention does not need to change the processing contents in the display data generating means for each format by acquiring a predetermined format using the format database. It is useful as an information providing apparatus that returns data corresponding to the request to the information terminal with reference to FIG.
