Description

  The present invention relates to a user interface mounting technique in a Web server system, and more particularly to a technique effective when applied to a dictionary system and a dictionary calling method that dynamically switch a display format for the same item with one source code.

  With the development of IT technology and the globalization of business, there is an increasing need to make websites and web applications compatible with multiple languages. As a technique for enabling access to a website or a web application in a plurality of language environments, for example, as a conventional technique, individual contents translated in each language for the same contents are prepared in advance. In addition, there is a technique in which these are automatically or manually selected and used according to the language environment used by the user. In addition to this, various techniques have been proposed as techniques for supporting multiple languages in application programs.

  For example, in Japanese Patent Application Laid-Open No. 2003-44474 (Patent Document 1), a language is determined based on client and user information, a skeleton of a content part including a content element is determined, and a saved translation of each skeleton content element Use tables or dynamic natural language translation of each skeleton content element to translate the skeleton content element into a language determined based on client and user information, and the translated skeleton content element into the content part Describes a technique for providing dynamic language translation of a content part by integrating with the above.

  Here, the data that holds the translation contents of the content elements for each language environment, such as the above translation table, is implemented as a dictionary composed of, for example, a file or a database, and the data in the dictionary is updated. Thus, the display contents and the translation contents are also changed dynamically.

JP 2003-44474 A

  According to the prior art, for example, in a Web server system, each item in the content is translated according to the language environment of the client terminal to be accessed, or the content in a state in which the display content is dynamically changed without being limited to translation It is possible to provide.

  However, in these techniques, one type (for example, for each language environment) of dictionary and translation table is normally defined for each Web server system. Therefore, for example, when there are a plurality of business operators that provide services on different websites using the system, the content differs for each website for the same item in the same language environment. Cannot be displayed (that is, different dictionary data is set for the item). Also, there are cases where it is desired to display different contents for the same item for each screen even within the same Web site.

  In other words, in a large-scale system, there are many cases in which the subject that manages the dictionary is different, such as items at the framework level common to the system, common items for each subsystem, items specific to the screen, etc. There is a problem that it is complicated and takes a long time to change. In addition, when the dictionary is divided and subdivided according to the management subject, there is a problem that it is difficult for each developer of the Web application to grasp which dictionary should be referred to.

  On the other hand, in a registered business system in a Web server, the number of characters and full-width characters of each input / output item when it is displayed on a client terminal screen or input from the screen, a method for checking an input value, and the like differ. Therefore, changing the name of the displayed input / output item according to the change of the language environment is not complete, and even if a dictionary for changing the name is implemented, the input / output is individually performed for each language environment. It was necessary to modify the program and source code for item attribute values and value check processing.

  Accordingly, an object of the present invention is to dynamically change the display format of the same item displayed on the screen in a Web application to different contents at different levels such as for each language environment, and further for each Web site and each screen. It is an object of the present invention to provide a dictionary system and a dictionary calling method that enable the above. The above and other objects and novel features of the present invention will be apparent from the description of this specification and the accompanying drawings.

  Of the inventions disclosed in this application, the outline of typical ones will be briefly described as follows.

  A dictionary system according to a typical embodiment of the present invention is a Web server system that provides a service by receiving a request from a client terminal, calling a corresponding business logic, and responding to the client terminal with a processing result. A dictionary system that provides dictionary data for a plurality of types of dictionary tables having a hierarchical structure with a higher application range as a higher range with respect to a range to which the dictionary data is applied, and the designated dictionary table A dictionary processing unit that acquires the dictionary data corresponding to the designated key, and the dictionary processing unit, when acquiring the dictionary data from the dictionary table, the hierarchy of any of the hierarchical structures Accepts the specification of whether to refer to the dictionary table, the specified key in the dictionary table of the specified hierarchy If the corresponding said dictionary data is not present, in which further sequentially to the dictionary table of the upper, characterized in that inquires whether with the dictionary data corresponding to the key.

  Among the inventions disclosed in the present application, effects obtained by typical ones will be briefly described as follows.

  That is, according to the exemplary embodiment of the present invention, in the Web application, the display format of the same item displayed on the screen is different for each language environment, and for different levels such as for each Web site and each screen. It is possible to easily change the contents dynamically.

It is the figure which showed the outline | summary about the example of the process at the time of changing about the external appearance etc. of the control displayed by the parts object in one embodiment of this invention.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. Note that components having the same function are denoted by the same reference symbols throughout the drawings for describing the embodiment, and the repetitive description thereof will be omitted.

  A multilingual Web server system having a dictionary system according to an embodiment of the present invention can provide a user interface in a plurality of languages without changing a source code. Create and hold. The dictionary not only holds text data such as display names translated in each language, but can also manage various attribute information of items as a data dictionary. That is, information unique to each language in the user interface can be held as dictionary data.

  By using such a dictionary, for example, it is possible to develop an application in a plurality of languages at the same time, and it is easy to add a corresponding language, and it is possible to improve extensibility. Further, by using it as a data dictionary, data items can be standardized in the system.

  In this embodiment, for example, in a CRUD (Create, Read, Update, Delete) type Web application program that accesses a business database, input / output items on the screen (for example, search conditions for acquiring data from the business database) Standard control objects (hereinafter sometimes simply referred to as “controls”) are used directly to display the contents related to input items that specify the contents of items and output items that display the contents of search results. Instead, a part object in which display name, control setting contents, control processing, and explanation text data are integrated is used as described later.

  This part object can specify what kind of control to display on the screen (for example, text control only, (text control and) input field, (text control and) drop-down list, etc.) as a parameter. Is possible. Control attribute values (for example, text content displayed in text controls, input field length, etc.), control information (for example, how to check validity of input data, etc.) It is also implemented to display and control controls according to specified content.

  In other words, the part object is displayed by combining an input / output control that handles input / output item data such as an input field, drop-down list, and text, and a label control that is a text control that displays the name of the input / output item. In this configuration, the output pattern of these controls can be specified.

  At this time, the attribute value such as the width of the control can be adjusted in a consistent manner for the label control and the input / output control at a time, so the attribute value etc. There is no need for a complicated process of designating, and the appearance of the displayed control can be adjusted. For this adjustment, for example, the display width of the label control and the input / output control is prevented so that the label control is not line-breaked at an unintended location or is not line-breaked at the intended location. For example, to adjust the unity.

  In the present embodiment, it is assumed that the source code is created so that the Web application program displays the contents relating to each input / output item on the screen using the part object. That is, the control is indirectly displayed by using the part object (HTML (HyperText Markup Language) data or script for displaying the target control when the part object is executed on the Web server system is dynamically generated). . Information relating to the mapping between each column of the database to be accessed and input / output items on the screen includes identification information (for example, column name) of each column of the database and identification information (for example, HTML of the corresponding part object). It is stored on the source code as mapping information with (ID attribute value).

  Furthermore, in this embodiment, as will be described later, the text displayed on the label control in each part object, the attribute value of the input / output control and the information related to the control processing, etc. are directly directly on the source code. Instead of specifying, it is configured to be stored as dictionary data associated with identification information such as part object ID or corresponding database column name. By defining the contents of this dictionary data for each language environment and referencing the dictionary data corresponding to the target language environment at the time of execution, the part object can be used without changing the generated source code. The appearance and attributes of controls displayed on the screen can be dynamically changed according to the language environment.

  In addition, by implementing the functions that part objects have in common, such as access to the above dictionary data, in the inheritance source class, during development, each part object is created by inheriting the class, A developer can develop a Web application program without implementing the function of a part object each time.

<System configuration>
FIG. 1 is a diagram showing an outline of a configuration example of a multilingual Web server system according to an embodiment of the present invention. The multilingual Web server system 100 includes, for example, computer devices such as a server device and a virtual server in a cloud computing environment. Each unit includes a request processing unit 110, a dictionary system 120, a business logic 130, and a response processing unit 140 which are implemented by a source code 101 created by a user or a software program such as a library or an object called from the source code 101.

  Further, the multilingual Web server system 100 responds to a request from a program such as a Web browser (not shown) on the client terminal 200 connected via a network 300 such as the Internet by a business logic 130 using a business database (DB). The service is provided by accessing 131 and performing processing, and outputting HTML data 102 to the client terminal 200 and responding.

  The request processing unit 110 has a function of receiving a request from the client terminal 200 and calling a content (business logic 130) based on the corresponding source code 101, an ID conversion unit 111 implemented by a software program, and an input Each unit includes a check unit 112 and the like. The ID conversion unit 111 identifies the identification information (ID) of the part object corresponding to the input item on the screen included in the request message, based on the mapping information held in the source code 101, and the business corresponding to the input / output item It has a function of converting to column identification information (column name, etc.) in the DB 131.

  This mapping information holds correspondence between part object identification information (for example, HTML ID attribute value) displayed on the screen and identification information (column name, etc.) of each column of the business DB 131 to be accessed. As a result, as will be described later, each part object arranged on the screen in the source code 101 first acquires a column name corresponding to its own ID by the ID conversion unit 111, and then uses the column name as a key to perform a task. Subsequent processing such as access to the DB 131 and acquisition of dictionary data from the dictionary table 122 described later can be performed.

  Therefore, on the HTML data 102 that responds to the client terminal 200, it is not necessary to directly specify the column name of the corresponding business DB 131 as information such as a key in each part object (the control displayed by), and the own ID is assigned. Since information such as a key can be used, security can be enhanced by hiding the actual column name from the HTML data 102. Instead of performing such conversion, the column name of the business DB 131 corresponding to each part object (control displayed by) on the HTML data 102 may be directly specified as information such as a key.

  The input check unit 112 has a function of performing a general validity check on the content of data of an input item specified via a part object (control displayed by) included in the request message. Possible types of validity checks include, for example, the number of characters and character type (numbers, alphabets, kana, full-width, etc.), restrictions on usable characters, format checks such as date and time, and various code values.

  The content of the validity check can vary depending on the language environment. Therefore, in the present embodiment, the input check unit 112 implements a plurality of patterns of validity checking types that take into account variations for each language, and determines which type to use for the target input item in the language environment. It shall be selected and determined accordingly. Here, the dictionary table 122 of the target language is accessed via the dictionary system 120 described later, and information on the validity check type is acquired and determined from the contents of the dictionary data corresponding to the target input item.

  The dictionary system 120 includes, for example, a dictionary processing unit 121 and a dictionary table 122 implemented by a database, a file table, or the like. The dictionary processing unit 121 searches the dictionary data for the specified key (in this embodiment, for example, the column name of the business DB 131 corresponding to the target input / output item (part object)) from the dictionary table 122 of the specified language. Has the function of acquiring and outputting The language designation may be acquired from, for example, the language environment of the web browser included in the request message from the client terminal 200, or the language may be defined for each web site operating on the multilingual web server system 100. Alternatively, this value may be acquired. In the example of FIG. 1, it is shown that the dictionary table 122 of each language of Japanese (“ja”), English (“en”), and Chinese (“zh”) is held.

  As will be described later, the dictionary table 122 has a hierarchical structure according to the application range and the management subject, and thereby, a different dictionary table 122 is mounted with minimum resources for each Web site or each screen. Making it possible.

  The contents and format of the dictionary data in the dictionary table 122 are not particularly limited. In the present embodiment, as a simple method, for example, as will be described later, various data necessary for performing input / output processing of data to a target column of the business DB 131 via a screen (for input / output) It is assumed that the attribute value of the part object, parameters necessary for control, etc.) are specified in a predetermined order by commas. Specifically, for example, the display name that is the content when displaying the label control in the corresponding part object, the length (number of characters) when the input field is displayed as the input / output control, the type of validity check, and the IME It is possible to specify specifications related to the contents of control processing such as the mode, abbreviated display name and display width that are shortened text when output data is displayed in a table, and a value list when displayed by a drop-down list, etc. .

  In the example of FIG. 1, the dictionary system 120 is configured to be mounted on the multilingual Web server system 100. However, the configuration is not limited thereto, and the dictionary system 120 is independent on a server device different from the multilingual Web server system 100. You may build it.

  The business logic 130 has a function of performing processing as a business application using the business DB 131. In the present embodiment, as described above, the CRUD type application for the business DB 131 is targeted, but the present invention is not particularly limited to this.

  The response processing unit 140 has a function of generating HTML data 102 based on the processing result of the business logic 130 based on the contents of the source code 101 and responding to the client terminal 200, and is a translation implemented by a software program Each unit includes a unit 141 and a display unit 142. For each output item included in the response, the translation unit 141 obtains parameter values such as label control text, input / output control attribute values, and control information for displaying the corresponding part object in the target language environment. To do. Here, the dictionary table 122 of the corresponding language is accessed via the dictionary system 120, and various parameter values such as display names and attribute values are acquired from the dictionary data corresponding to the target output item (part object).

  In the display unit 142, the controls displayed by each part object are arranged based on the label control text, the attribute value of the input / output control, and the parameter values such as control information obtained by the translation unit 141. A function to generate HTML data 102 of the response screen.

<Screen display processing>
FIG. 2 is a diagram showing an outline of an example of processing when displaying a column input / output item corresponding to a part object in a CRUD type application on a screen. In the example of FIG. 2, an example in which an input field for specifying “customer name” is displayed on a screen for inputting a search condition when reading data from the business DB 131 in a Japanese environment is shown.

  In the source code 101 of the Web application program shown in the upper part of the figure, the part object 103 is called to display an input field for designating “customer name”. Specifically, first, the column name corresponding to the ID (“A01”) from the mapping information held in the source code 101 (in the example of FIG. 2, the correspondence is held by array ()). Get "customer_name") information.

  Thereafter, for example, a subclass inherited from a class that implements the function of the part object 103 is called in the form of creating an instance (“CF_itemDic ();”). In the example of FIG. 2, as part of the parameters, the type of dictionary table 122 to be called (“common dictionary”), the type of input / output control to be displayed (“input field”), the HTML ID attribute value (“A01”), etc. The state called by specifying is simplified. The HTML ID attribute value (“A01”) is dynamically converted into a column name (“customer_name”) by mapping information.

  The part object 103 called by such a code holds data including at least a display name (text of label control) and information related to the contents of the input / output control to be displayed. As shown in FIG. 2, other information such as explanatory text may be further held. In the example of FIG. 2, among the above three pieces of information of the part object 103, since “input field” is specified as a parameter in the source code 101 for the control, this is set.

  The called part object 103 further accesses the target dictionary table 122 (“common dictionary”) in the Japanese environment (“ja”) via the dictionary processing unit 121 of the dictionary system 120 by a predetermined function or method. Then, dictionary data (a set of a plurality of values such as “customer name”, 40 characters, 20 characters,...) Corresponding to the column name (“customer_name”) is acquired.

  In the example of FIG. 2, as dictionary data in the dictionary table 122, in order from the top, the name (text to be displayed on the label control), the length in the case of the input field (number of characters in half-width), and the maximum length in the case of the input field (Number of characters), validation type of input data, initial mode of IME, explanatory comment, text (display name) for list display in table, display width (pixel value) for list display in table, etc. Information shall be retained. As an output format when acquiring these dictionary data, for example, a series of character strings in which these values are separated by a comma or the like may be used, or easily accessible data such as an associative array may be used.

  For the dictionary table 122, in consideration of processing efficiency, it is desirable to expand the contents of the dictionary data in the memory at the time of initial processing or first access. In this case, if all the dictionary data is expanded, the processing efficiency may be reduced due to the pressure on the memory usage or the time required for the expansion processing. Therefore, in terms of implementation, it is desirable that dictionary data in a necessary range can be expanded on a memory when necessary.

  In view of this, the present embodiment has a hierarchical structure composed of a plurality of dictionary tables 122 having different application ranges and management subjects, and adopts a configuration in which these are appropriately selected and used. FIG. 3 is a diagram showing an outline of an example of the hierarchical structure of the dictionary table 122. In the hierarchical structure, in order from the top, for example, a plurality of common dictionaries 122_z that are common dictionary tables 122 for each language environment of a system or application operating on the multilingual Web server system 100, only within a designated Web site A plurality of types of dictionary tables 122 having different application ranges and management subjects, such as a plurality of common site dictionaries 122_s, a plurality of library dictionaries 122_l that are common only within the subsystem, and a plurality of controller dictionaries 122_c in units of screens (Note that a part of the hierarchical structure is extracted and the other parts are omitted).

  In this case, for example, when the corresponding dictionary data is not obtained by referring to a dictionary having a narrow application range such as the lower-layer controller dictionary 122_c, the upper ( It may be possible to refer back to the dictionary table 122 (which has a wide application range). At this time, it may be possible to define permission / refusal of referring back to each hierarchy, or allow permission / refusal of referencing of the dictionary table 122 to be defined for each hierarchy.

  For example, when the corresponding dictionary data is not obtained by referring to the “controller dictionary a” in the figure, if it is permitted to refer back to the library dictionary 122_l, the upper “library dictionary c” Refer to At this time, when use of the library dictionary 122_l is not permitted in the target Web application, it is permitted to refer back to the site dictionary 122_s in the library dictionary 122_l, assuming that dictionary data has not been obtained. Refers to the upper “site dictionary a”. As described above, when the dictionary data is not finally obtained even when the hierarchical structure is traced back, a default value may be used or an error may be generated.

  By adopting such a configuration and using different dictionary tables 122, it is possible to maintain the dictionary data expanded on the memory at an appropriate size only for what is necessary. In addition to the common dictionary 122_z, for example, by having a site dictionary 122_s that can set common dictionary data for each site, a website owner or administrator can access the web regardless of the setting contents at other sites. Unique dictionary data can be created freely and flexibly only within the site. Further, by adopting such a hierarchical structure, it is only necessary to define a difference with respect to the upper layer dictionary table 122 in the lower layer dictionary table 122, and it is possible to improve development productivity.

  Returning to FIG. 2, the part object 103 extracts necessary data from the acquired dictionary data and sets it as a parameter for displaying and controlling the control. For example, the length of the field acquired from the dictionary data is set as an attribute value when displaying the input field as an input / output control, and the value of the validity check type, the initial mode of IME, the contents of the explanatory text, etc. Set. The processing related to input / output control such as validity checking of input data and IME mode setting is a function of the input check unit 112 and the display unit 142. Specific implementation includes, for example, parts It is assumed that the part object 103 is implemented as a function that the part object 103 has or can be called by, for example, defining it as a method in the inheritance source class of the object 103.

  As a result, as shown in the lower screen example in FIG. 2, the part object 103 can generate the HTML data 102 so as to display the control of the input field for designating the “customer name” at the time of execution. At this time, for example, the description text information of the part object 103 can be used as help information for the input / output item.

  When displaying the input field, since only the input field control is displayed, it is unclear what should be input. Therefore, in this embodiment, as shown in FIG. A text control ("customer name") that displays the display name of the input / output item is displayed adjacent to the input field as a label (label control). The text sets display name information in the retained data of the part object 103, that is, the name value (“customer name”) of the dictionary data acquired by the part object 103 from the dictionary table 122.

  Such processing related to the generation of the HTML data 102 is a function of the display unit 142 or the like. As a specific implementation, for example, a part is defined as a method in a class inherited from the part object 103. It is assumed that the object 103 is implemented as a function that the part object 103 has or can be called. Here, as described above, the attribute values relating to the appearance and the like are adjusted in a consistent manner for the three elements of the label control, input / output control, and explanatory text to be displayed. .

  Thus, in the present embodiment, it is possible to generate HTML data 102 that displays input / output items by the part object 103. Therefore, the CRUD-type application in the present embodiment is arranged so that the part object 103 is arranged on the screen according to a predetermined rule as an input / output item corresponding to each column of the business DB 131 and combined with the implementation of standard functions and operations. This can be realized by creating the code 101. Also, a function for automatically generating such source code 101 can be implemented as an application program development support system or the like.

  For example, as an application for registering an entry in the business DB 131 (C: Create), a part object 103 for displaying an input field for designating data to be registered for each column of the business DB 131 is displayed on the screen. The source code 101 is created so as to be arranged according to the column arrangement order of the DB 131. At this time, the correspondence between the ID of the control displayed on the screen and the name of the column is held as mapping information as necessary. Furthermore, as a standard function, a “registration” button, a “cancel” button, and the like for executing entry registration in the business DB 131 are arranged. Further, the dictionary table 122 for each language environment holds information such as attribute values and control information used when displaying controls for each part object 103 as dictionary data. At this time, each item is set with a default value unless otherwise specified.

  Further, for example, as an application for performing a search (R: Read) with respect to the business DB 131, a part object 103 for displaying an input field for designating a condition for searching the business DB 131 on the screen is arranged as described above. The source code 101 is created to At this time, if all the columns of the target table of the business DB 131 can be specified as a search condition, it becomes excessive. For example, the input fields are temporarily displayed only for the first five columns, and then It is good also as changeable from. Further, the correspondence between the ID of the control displayed on the screen and the column name is stored as mapping information as necessary. Furthermore, a “search” button or the like for searching for entries in the business DB 131 is arranged as a standard function.

  Further, for example, a table control for displaying the search result is automatically arranged below the area for inputting the search condition. Here, for example, the content corresponding to the call of the part object 103 corresponding to each column of the business DB 131 is set in the item definition array of the table control object. Thus, the display unit 142 or the part object 103 can be mounted so that the contents of each column of the business DB 131 are displayed in each column of the table control.

  In this state, in order to make the Web application compatible with another different language without changing the contents of the source code 101, a dictionary table 122 for the target language may be prepared. FIG. 4 is a diagram showing an outline of an example of processing when changing the appearance or the like of the control displayed by the part object 103 to another language. Here, the contents of the source code 101 shown in the example of FIG. 2 are not changed, and a new dictionary table 122 for the English environment (“en”) is created.

  Thus, when the Web application is executed, the part object 103 refers to the contents of the entry in the target dictionary table 122 in the English environment (“en”), and the screen example in the lower part of FIG. 4 is displayed according to the contents. As shown, not only the text data of the label control as the display name but also the attributes of the input / output control, etc. (in the example of FIG. 4, the input field length (width), the contents of the validity check of the input data, the IME mode, etc. ) Can be dynamically changed to the English environment.

  FIG. 5 is a diagram showing an outline of an example of processing when changing the appearance or the like of the control displayed by the part object 103. Here, simple changes are made to the contents of the source code 101 shown in the example of FIG. Specifically, when the part object 103 is called, the parameter of the type of input / output control to be displayed is changed from “input field” to “drop-down list”. The dictionary table 122 additionally defines the contents of the value list set in the drop-down list (“Tanaka: 1, Yamamoto: 2,...”) At the end of the dictionary data.

  Thereby, when the Web application is executed, the part object 103 can generate the HTML data 102 so as to change the display content of the input / output item by the specified type of input / output control. In the example of FIG. 5, the input / output control is changed from the input field to the drop-down list for the same part object 103. For example, when the parameter of the input / output control type is set to “text”, the part The object 103 displays the value as text. Only one of the label control and the input / output control can be displayed. If the parameter is set to “Hide”, data is retained internally, but no control is displayed for the input / output item on the screen display.

  As described above, according to the multilingual Web server system 100 having the dictionary system 120 according to an embodiment of the present invention, information (input / output items) unique to each language in the user interface of the Web application program. Are stored in the dictionary table 122 for each language environment as dictionary data. In addition, when displaying input / output items on the screen, the Web application does not directly use standard controls but indirectly displays standard controls using the part object 103. .

  This part object 103 includes corresponding dictionary data from the dictionary table 122 corresponding to the language environment, and includes the appearance and attributes of controls for displaying input / output items on the screen based on the contents, control processing, and the like. Change the user interface dynamically. As a result, the user interface can be dynamically changed according to the language environment without changing the source code 101 of the application.

  Further, by configuring the dictionary table 122 as a hierarchical structure according to the application range and the management subject and using them appropriately, it is possible to maintain the dictionary data expanded on the memory in an appropriate size as much as necessary. In addition, for example, by having a common site dictionary 122_s for each site, the owner and administrator of the website can freely and uniquely store unique dictionary data only in the website regardless of the setting contents in other sites. It can be created flexibly. Further, by adopting such a hierarchical structure, it is only necessary to define a difference with respect to the upper layer dictionary table 122 in the lower layer dictionary table 122. For example, a specific screen for the definition of the basic subsystem unit. It is also possible to improve development productivity and ease of management, such as making exception setting easier. Due to the effects as described above, it becomes easy to correspond to a service provision form such as SaaS (Software as a Service).

  As mentioned above, the invention made by the present inventor has been specifically described based on the embodiment. However, the present invention is not limited to the embodiment, and various modifications can be made without departing from the scope of the invention. Needless to say. For example, in this embodiment, a standard CRUD type Web application is targeted, but the present invention is not limited to this. A unique application (including not only a Web application but also a client / server type or a stand-alone type) that is constructed by the user in combination with the dictionary table 122 and the part object 103 and including operation contents such as a user interface and business logic. However, it is possible to define a dictionary table 122 for each language environment and support multiple languages based on the same concept.

  In the present embodiment, the common dictionary 122_z is provided corresponding to the language environment. However, the present invention is not limited to this, and for example, data items having different names and meanings depending on regions, types of business, and the like are individually stored in the common dictionary 122_z. It may be used such as defining. In the present embodiment, the dictionary table 122 is an example in which various attribute information and the like of input / output items are stored as a data dictionary, but the translated text in each language for text data such as a display name is stored. Even in this case, the same effect as described above can be obtained by adopting a hierarchical structure.

  In the present embodiment, since the part object 103 has a function (method) for calling the dictionary system 120 and accessing the dictionary table 122, each control on the screen accesses the dictionary table 122. However, the use of the dictionary system 120 is not limited to such a configuration. Instead of using the part object 103, it is possible to describe each control on the screen so that the dictionary data is acquired by directly calling the dictionary system 120 on the source code 101.

  The present invention can be used for a dictionary system and a dictionary calling method that dynamically switch the display format for the same item with one source code.
