Description

  The present invention relates to a screen program generation device for automatically generating a screen program.

In the development of screen programs such as business systems, there is an approach for automatically generating screen programs as a method for improving development productivity.

Conventionally, as such an apparatus and method for automatically generating a screen program, as described in JP-A-2004-302571 and JP-A-2002-215393, a screen program is automatically generated based on screen design information. In addition to reducing programming man-hours, there is a technique that improves development productivity by eliminating the manual labor of synchronizing design information and programs.

In general, in screen programs, it is important that the screen design is unified from the viewpoint of user operability. For this reason, the screen is composed of a common frame. For example, a common area including elements such as a screen title and a global navigation such as a crumb trail is formed on the entire screen, and a common UI (User Interface) of the screen is formed. It is desirable to make the screen design common, for example, to make the parts have the same design regardless of the screen, for example, the button for logging out is the same “logout” regardless of the screen.

However, in the apparatus described in Japanese Patent Application Laid-Open No. 2004-302571, screen design information is defined for each screen constituting the screen program, and each screen program is automatically generated by inputting each screen design information. The specifications of the common part are distributed in the design information of each screen. Therefore, when changing the specification of the common part during program enhancement (addition of a new function), it is necessary to individually correct the information of the common specification scattered in each screen design information.

Such work needs to be done carefully by hand to maintain consistency, and there is a risk of human error, so extra work is required to maintain the specifications.

That is, when considering the entire development life cycle including the enhancement of the program, the productivity described in Japanese Patent Application Laid-Open No. 2004-302571 may impede development productivity in terms of maintenance man-hours for specifications.

On the other hand, in the method described in Japanese Patent Laid-Open No. 2002-215393, one template is prepared for the entire screen program, and design information for each screen is defined for each screen. According to this method, with respect to a screen program in which the screen has one common frame as a whole, the screen design information of the common part can be aggregated in one place, and the problem of the maintenance man-hour of the specification can be avoided.

JP 2004-302571 A JP 2002-215393 A

However, in general, there are cases in which screen programs have commonality that cannot be expressed by templates, such as cases having different frames for each screen group and cases in which frames are hierarchical, in such cases, The method described in 2002-215393 cannot respond.

Furthermore, in the method using a template such as the method described in Japanese Patent Laid-Open No. 2002-215393, when defining the specification information of the screen program, the specification of the entire screen needs to be clear in order to cut out the common part of the entire screen. is there.

Moreover, in the iterative development process that is generally performed in recent years, it is difficult to clarify the specifications of the full screen at the first stage, and when the template method is applied to such a process, as the development progresses When a screen that does not match the template appears, it takes a lot of work to modify the template and full screen specification definition.

An object of the present invention is to manage specification definition information of a plurality of screens by distinguishing them between specification definition information common to each screen and specification definition information specific to each screen, and automatically correct the specification definition information common to each screen during enhancement. An object of the present invention is to provide a screen program generation apparatus capable of

In order to achieve the above object, the present invention stores the screen specification definition information related to a plurality of screens separately in the screen specification definition information related to a part common to each screen and the screen specification definition information related to a part specific to each screen, Of the screen specification definition information related to the portions common to each screen, the screen specification definition information related to the screen interface component and the screen specification definition information related to the structure are stored as one screen specification definition information. At this time, when it is necessary to change the screen specification definition information common to a plurality of screens during program enhancement, each of the screen specification definition information can be automatically corrected.

According to the present invention, it is possible to automatically correct the specification definition information common to each screen at the time of enhancement without securing manpower.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

In this embodiment, when generating a screen program of a plurality of screens having a plurality of display areas and screen UI parts arranged in any of the display areas as component elements, the screen UI part definition information common to the screens is generated. Store as one screen UI component definition information, store screen structure fragment definition information common to each screen as one screen structure fragment definition information, and modify one screen UI component definition Information and one screen structure fragment definition information are each corrected.

FIG. 1 is a configuration diagram showing an embodiment of a screen program generation system to which a screen program generation device according to the present invention is applied. In FIG. 1, the screen program generation system includes a display device 101, an input device 102, and a screen program generation device 103 of the present embodiment.

The display device 101 is connected to the screen program generation device 103, and presents information graphically to the user when editing the screen specification definition information. The display device 101 also notifies the user of information on the execution status of the generation process, such as notification of the execution status of the program code generation process of the screen program.

The input device 102 is connected to the screen program generation device 103. When editing the screen specification definition information, the screen specification definition information is interactively input to the screen program generation device 103 in response to a user operation. To do. The input device 102 interactively controls generation processing such as execution and stop of the program code generation processing of the screen program and grasping the execution status.

The screen program generation device 103 includes a definition information editing unit 104, a screen UI (user interface) part definition information storage unit 105, a screen structure fragment definition information storage unit 106, a screen configuration definition information storage unit 107, and a screen program code. A generation unit 108, a screen UI part code generation rule storage unit 109, a screen structure fragment code generation rule storage unit 110, a screen program code storage unit 111, and a screen specification definition information reconfiguration unit 112 are configured.

The definition information editing unit 104, the screen program code generation unit 108, and the screen specification definition information reconfiguration unit 112 include, for example, a CPU (Central Processing Unit) or a microprocessor, and the CPU or microprocessor includes a definition information editing program, The definition information editing unit 104, the screen program code generation unit 108, or the screen specification definition information reconfiguration unit 112 is configured by starting the screen program code generation program or the screen specification definition information reconfiguration program.

  Screen UI part definition information storage unit 105, screen structure fragment definition information storage unit 106, screen configuration definition information storage unit 107, screen UI part code generation rule storage unit 109, screen structure fragment code generation rule storage unit 110, The screen program code storage unit 111 is configured by a memory such as a RAM (Random Access Memory), for example.

For example, when the screen for generating the screen program is composed of a plurality of screens, the definition information editing unit 104 edits the screen specification definition information that is information defining the specifications of each screen. The screen specification definition information includes three types of information: screen UI component definition information, screen structure fragment definition information, and screen configuration definition information.

The definition information editing unit 104 inputs and outputs the screen specification definition information stored in each of the storage units 105, 106, and 107 via the display device 101 and the input device 102. For example, the definition information editing unit 104 inputs three types of screen specification definition information from the input device 102, stores the screen UI component definition information in the screen UI component definition information storage unit 105, and stores the screen structure fragment definition information in the screen structure. The information is stored in the fragment definition information storage unit 106, and the screen configuration definition information is stored in the screen configuration definition information storage unit 107.

For example, when each screen includes a plurality of display areas and screen UI parts arranged in one of the display areas, the screen UI part definition information storage unit 105 includes screen UI parts such as buttons and labels. The screen UI component definition information, which is the definition information of the specifications relating to the above, is stored. When the screen program to be generated by the screen program generation device 103 is, for example, a screen program for configuring a plurality of screens, the screen UI component definition information storage unit 105 unifies all screen UI component definition information. Manage and remember.

At this time, regarding the screen UI parts that are commonly used in a plurality of screens, the screen UI part definition information is stored as one definition information. That is, the screen UI component definition information storage unit 105 stores the screen UI component definition information by distinguishing the screen UI component definition information into the screen UI component definition information unique to each screen and the screen UI component definition information common to each screen. The part definition information is stored as one definition information.

  The screen structure fragment definition information storage unit 106 stores screen structure fragment definition information that is screen specification definition information related to the structure fragment of each screen. Each screen forms a structure by mutual inclusion of components such as UI parts and rectangular areas. The structural fragment is a partial structure of the screen structure of each screen. For example, in the case where the screen is configured with HTML (HyperText Markup Language), for example, the screen can be expressed by the hierarchical structure of the grid, so the structural fragment has a partial hierarchical structure of the grid.

At this time, lines defining the display area of the screen, for example, vertical lines and horizontal lines are set as grids, and cells are displayed in the display area (rectangular area) surrounded by the vertical grid and the horizontal grid. Then, when this cell is divided into a plurality of display areas by a plurality of vertical grids and a plurality of horizontal grids, small cells are formed in the respective display areas obtained by this division. It will be.

FIG. 2 is an example of the hierarchical structure of the grid. The uppermost grid 201 is a grid in which two cells 211 and 212 are arranged in the vertical direction. When the grid 201 is a parent grid, the upper cell 211 includes a child grid 202, and the lower cell 212 includes a child grid 203. The child grid 202 is a grid in which three cells 213, 214, and 215 are arranged in the horizontal direction, and each cell 213, 214, and 215 does not include a grid. The child grid 203 is a grid in which two cells 216 and 217 are arranged in the vertical direction, and the lower cell 217 includes a child grid 204.

A structure including a grid 201, a grid 202, and a grid including all of the grid 203 and the grid 204 is also a structural fragment, and each partial structure, for example, a structure including the grid 203 and the grid 204 is also a structural fragment. is there. Note that a screen UI component that is a UI element of each screen is arranged in any cell.

In the case of a set of screen programs to be generated by the screen program generation device 103, for example, a screen program constituting a plurality of screens, the screen structure fragment definition information storage unit 106 manages the partial structure of all the screens. A partial structure common to a plurality of screens is stored as one definition information in the screen structure fragment definition information storage unit 106. That is, the screen structure fragment definition information storage unit 106 displays the screen structure fragment definition information, which is the screen specification definition information related to the structure fragment indicating the partial hierarchical structure of each screen, and the screen structure fragment definition information common to each screen. The screen structure fragment definition information is distinguished and stored, and the screen structure fragment definition information common to each screen is stored as one screen structure fragment definition information.

  The screen configuration definition information storage unit 107 stores screen configuration definition information that is specification definition information related to the screen configuration. In the case of a set of screen programs to be generated by the screen program generation apparatus 103, for example, a screen program for configuring a plurality of screens, the screen configuration definition information storage unit 107 stores the structure definition information of each screen for each screen. Remember one by one.

  At this time, the screen configuration definition information storage unit 107 stores screen configuration definition information that includes screen specification definition information related to the configuration of each screen and includes information related to a connection point between a portion unique to each screen and a portion common to each screen.

The information is converted into a code according to a code generation rule, a screen program code is mechanically generated, and the generated screen program code is stored in the screen program code storage unit 111.

  The screen UI component code generation rule storage unit 109 generates program code fragments from the screen UI component definition information for each type of screen UI component for the screen UI component definition information stored in the screen UI component definition information storage unit 105. A screen UI part code generation rule, which is a code generation rule for storing the screen UI, is stored.

  The screen structure fragment code generation rule storage unit 110 generates a screen structure fragment code generation rule that is a code generation rule for generating a program code fragment from the screen structure fragment definition information stored in the screen structure fragment definition information storage unit 106. Remember.

The screen program code storage unit 111 stores the screen program code generated by the screen program code generation unit 108.

The screen specification definition information reconfiguration unit 112 divides the screen structure fragment definition information stored in the screen structure fragment definition information storage unit 106, and includes the screen configuration definition information stored in the screen configuration definition information storage unit 107. Then, the screen configuration definition information that has referred to the divided screen structure fragment definition information is reconfigured so as to refer to the divided structure fragment definition information.

Each screen (the first screen and the second screen) has a common frame portion (a grid common to each screen) 403, and the screen title 401 and the end button 402 in the upper screen 404 are common to each screen. In this case, the screen title 401 of the screen UI component and the end button 402 are arranged in two display areas (cells) surrounded by the grid constituting the upper screen 404.

The lower screen portion 405 is different for each screen. For example, the first screen-specific portion 408 includes a text field 406 and a search button 407 as screen UI parts specific to the first screen. The second screen-specific portion 409 includes an edit button 410, a cancel button 411, and the like as screen UI parts specific to the second screen.

FIG. 5 shows screen UI component definition information stored in the screen UI component definition information storage unit 105. The screen UI component definition information related to one screen UI component includes a screen UI component ID (IDentifier) 501, a name 502, a type 503, a display character string 504, and zero or more attribute values as one element of the screen specification definition information. It consists of attributes (attributes and attribute values are paired) 505-508.

The screen UI component ID 501 is an identifier for uniquely identifying the screen UI component. A name 502 is a name of the screen UI component and is intended to help the user understand. A type 503 is an identifier indicating the type of the screen UI component, such as a button or one-line text input. The display character string 504 is a character string expression when the screen UI component is displayed on the screen. Attributes 505 to 508 including attribute values are information for determining the detailed behavior and appearance of the screen UI component, and the attributes to be specified differ depending on the type 503.

In the record 1106, the second screen is composed of two structural fragments STR0001 and STR0003, and the structural fragment STR0003 is defined to be coupled to the connection point LNK0001 of the structural fragment STR0001.

  That is, the first screen includes a structural fragment STR0001 corresponding to the frame portion 403 common to each screen and a structural fragment STR0002 corresponding to the first screen specific portion 408. The structural fragment STR0002 is a combination of the structural fragments STR0001. Connected to point LNK0001. The second screen includes a structural fragment STR0001 corresponding to the frame portion 403 common to each screen and a structural fragment STR0003 corresponding to the second screen specific portion 409. The structural fragment STR0003 is a connection point LNK0001 of the structural fragment STR0001. Is bound to.

At this time, the screen configuration definition information storage unit 107 stores screen configuration definition information including information about a connection point between a portion unique to each screen and a portion common to each screen as screen specification definition information regarding the configuration of each screen. become. In addition, the screen structure fragment definition information storage unit 106 stores the screen structure fragment definition information separately in screen structure fragment definition information unique to each screen and screen structure fragment definition information common to each screen, and screen UI component definition information. Are stored in association with the screen configuration definition information.

Next, an operation flow for generating a screen program code for the first screen-specific portion 408 in FIG. 4 will be described.

The screen program code generation unit 108 acquires the screen configuration definition information 1105 related to the screen (the first screen-specific portion 408) from the screen configuration definition information storage unit 107, and the highest order from the acquired screen configuration definition information 1105. The ID “STR0001” of the structure fragment is acquired. The highest structural fragment can be identified from the fact that the parent structural fragment ID has no value. Using the acquired structure fragment ID “STR0001” as a key, the XML data of the structure fragment definition content 602 of the record 603 (the structure fragment definition content of FIG. 8) as the structure fragment definition information of the record 603 from the screen structure fragment definition storage unit 106. Data obtained from).

The screen program code generation unit 108 generates a code corresponding to the grid shown in the flowchart of FIG. 12 for the grid element immediately below the structural fragment element of the acquired XML data.

First, in the grid start code generation process (S1201), the screen program code generation unit 108 determines that the type 1402 is “from the screen structure fragment code generation rule (see FIG. 14) stored in the screen structure fragment code generation rule storage unit 110”. The code generation rule 1403 of “grid start” is acquired, and the code “<table>” having the contents stored in the generation program code fragment 1402 is generated.

In the loop portion, loop processing (S1202 to S1204) is performed for each row element under the grid element.

That is, in the line start code generation process (S1203), the code generation rule 1405 having the type “line start” 1401 is acquired from the screen structure fragment code generation rule storage unit 110, and the code of the content stored in the generation program code fragment 1402 is stored. “<Tr>” is generated.

In the next loop portion, loop processing (S1204 to S1212) is performed for each column element under the row element.

That is, in the column start code generation 1205, the code generation rule 1407 whose type 1401 is “column start” is acquired from the screen structure fragment code generation rule storage unit 110, and the code “<td” of the content stored in the generation program code fragment 1402 > ”Is generated.

In steps S1206 to S1210, the process branches depending on the element type below the column element, and the screen program code generation unit 108 executes the following process depending on the element type below the column element.

(1) In the case of a grid element For the grid, steps S1201 to S1206 are recursively called to generate a screen program code corresponding to the grid (S1207).

(2) In the case of a screen UI component ID element From the screen UI component definition information storage unit 105, the screen UI component ID 501 is used as a key to acquire the screen UI component definition information of the screen UI component, and the screen UI component code generation rule storage unit From the screen UI part code generation rule (FIG. 13) stored in 109, the type 1301 acquires the generated program code fragment 1302 corresponding to the type 503 of the screen UI part, and the screen according to the generated generated program code fragment 1302 A program code is generated (S1209).

For example, if the screen UI component ID 510 is “ELM0001”, since the type 503 is “label” in the record 509 of the screen UI component definition information, the record 1303 of the screen UI component code generation rule corresponds to the record 1303. Of the contents of the generated program code fragment 1302, the attribute parameter “[font size]” and “[character style]” are replaced with the font of the attribute 505 defined in the record 509 of the screen UI component definition information in FIG. The attribute value “18pt” of the size is replaced with the attribute value “bold” of the character style of the attribute 506.

(3) In the case of the connection point ID element, the structure fragment ID “STR0002” of the structure fragment having the connection point as the connection destination is acquired from the screen configuration definition information 1105 related to the screen, and the acquired structure fragment ID “STR0002” is the key Next, the structure fragment definition content 602 corresponding to the record 604 of the screen structure fragment definition information in FIG. 6 is acquired from the screen structure fragment definition information storage unit 106, and the XML data (structure fragment in FIG. 9) of the structure fragment definition content 602 is obtained. Data obtained from definition contents).

For the grid element immediately below the structure fragment element of the acquired XML data, a screen program code corresponding to the grid element is generated (S1210).

Next, in the column end code generation process, the content of the record 1408 whose type 1401 is “column end” is acquired from the screen structure fragment code generation rule storage unit 110, and the content code “1” stored in the generated program code fragment 1402 is stored. </ Td> "is generated (S1211).

Thereafter, in the loop portion, loop processing (S1212 to S1214) is performed for each row element under the grid element.

In the line end code generation process, the content of the record 1406 whose type 1401 is “line end” is acquired from the screen structure fragment code generation rule storage unit 110, and the code “</ tr” of the content stored in the generated program code fragment 1402 is obtained. > "Is generated (S1213).

Next, in the grid end code generation processing, the content of the record 1404 whose type 1401 is “grid end” is acquired from the screen structure fragment code generation rule storage unit 110, and the code “of the content stored in the generated program code fragment 1402“ </ Table> "is generated (S1215).

When the processing of steps S1201 to S1215 is completed, the screen program code generation unit 108 stores the generated screen program code in the screen program code storage unit 111.

  As described above, among the plurality of screens, for example, when generating the screen program code related to the first screen, the screen structure fragment definition information of the frame portion 403 common to each screen is referred to, and the frame portion common to each screen is referred to. XML data related to the structural fragment STR0001 403 is sequentially converted into a screen program code. In this process, for example, when the screen UI element ID includes XML data, the screen UI component definition information in FIG. When the XML data related to the definition information is sequentially converted into the screen program code and there is XML data indicating the coupling point ID, the screen configuration definition information in FIG. 11 is referred to and the structural fragment STR0002 of the first screen specific portion 408 is related. After the XML data is sequentially converted into the screen program code and these conversion processes are completed, the frame portion 403 common to each screen is configured. XML data related to the structure fragment STR0001 is sequentially converted into a screen program code.

In the present embodiment, when the screen specification definition information is stored in each storage unit, if the screen specification definition information related to the common part of each screen is related to the screen UI component, the screen UI component definition information storage unit 105 stores the screen specification definition information. Since the screen structure fragment definition information storage unit 106 stores one piece of the screen specification definition information, the definition information editing unit 104, for example, enhances the screen program. When it is necessary to change the screen specification definition information common to a plurality of screens, and when an instruction to modify the screen specification definition information common to each screen is received from the input device 102 that is the editing request source, one piece of screen specification definition information is It can be automatically corrected according to the instruction for correction.

  Therefore, according to this embodiment, when changing the specifications of each screen common part, for example, when enhancing the screen program, only one place needs to be corrected, and the screen specification definition information of each screen common part is changed. The advantage is that no human intervention is required to ensure consistency.

In addition, according to the present embodiment, since specifications relating to two screen structures can be defined by hierarchical combination of structural fragments, cases and frames having different frames for each screen group that cannot be represented by a template as in the past are hierarchical. Even in this case, there is an advantage that common specifications can be defined collectively.

In this embodiment, when a common frame structure of a screen is already stored in the screen structure fragment definition information storage unit 105 as a screen structure fragment definition, a new screen having a partial structure that does not partially match the frame structure When it becomes necessary to re-add, the existing common frame structure is reconfigured and a screen specification definition of a new screen is added.

FIG. 15 shows an example of a structural fragment of two screens (first screen and second screen) in the present embodiment. The screen structure fragment having the grid 1501 as the highest level is a common frame of each screen. Of the two cells 1521, 1522 belonging to the grid 1501, the upper cell 1521 includes a grid 1503, and the lower cell 1522 includes a grid 1502. Of the two cells 1523, 1524 belonging to the grid 1502, the upper cell 1523 includes the grid 1504, and the lower cell 1524 includes the connection point 1505. Each screen-specific (individual) partial grid structure (the first screen-specific partial grid structure or the second screen-specific partial grid structure) is connected to the connection point 1505. It is assumed that the screen structure fragment definition information having the grid 1501 as the highest level is already stored in the screen structure fragment definition information storage unit 105.

A grid 1506 is a screen structure fragment of a newly added screen. The grids 1506, 1507, and 1508 are the same as the grids 1501, 1502, and 1503 of the common frame of each screen, respectively, and only the grid 1509 that belongs to the cell 1533 above the grid 1507 is different from the grid 1504 of the common frame of each screen. ing.

Of the two cells 1531 and 1532 belonging to the grid 1506, the upper cell 1531 includes the grid 1508, and the lower cell 1532 includes the grid 1507. Of the two cells 1533, 1534 belonging to the grid 1507, the upper cell 1533 includes the grid 1509, and the lower cell 1534 includes the connection point 1510.

FIG. 16 shows the flow of the entire operation when reconstructing an existing common frame structure and adding screen specification definition information for a new screen.

First, the definition information editing unit 103 executes processing for selecting a target structure fragment definition, and via the display device 101 and the input device 102, the structure fragment ID 1101 of the screen structure fragment definition corresponding to the target screen frame structure to be reconfigured. The information regarding is received from the user (S1601).

Next, the definition information editing unit 103 executes a difference grid selection process, and the difference is a top-level grid having a partial structure that is different between the screen frame structure selected by the user and the frame structure of the newly added screen. As information about the grid, for example, information on the grid 1504 is received from the user (S1602).

Next, the screen specification definition information reconstructing unit 112 executes a screen structure fragment division process, and stores the screen structure fragment definition information in the screen structure fragment definition information storage using the selected structure fragment ID as information regarding the difference grid. Obtained from the unit 106, the structure fragment is divided by the following procedure.

(1) The structure fragment definition information having the highest parent grid of the difference grid is newly added to the screen structure fragment definition information storage unit 106.
(2) For the target structural fragment definition information, replace the parent grid of the difference grid with a connection point.

FIG. 17 shows an example in which the above-described structural fragment division is performed on the example of the screen shown in FIG. The structure fragment having the grid 1502 as the highest level is a structure fragment newly added from the structure fragment having the parent grid 1502 as the highest level of the grid 1504 that is the difference grid. In the structural fragment having the grid 1501 as the highest level, the parent grid 1502 of the difference grid 1504 is replaced with the connection point 1505.

Next, the screen specification definition information reconfiguration unit 112 executes a screen configuration definition update process, and sets target screen structure fragment definition information among the screen configuration definition information stored in the screen configuration definition information storage unit 107. Then, update is performed to add the screen structure fragment definition information added by the division to all the screen configuration definition information referred to (S1604).

FIG. 18 shows an example when the screen configuration definition information is updated with respect to the screen example shown in FIG. The screen configuration definition information shown in (a) of FIG. 18 is information before update, and the screen configuration definition information shown in (b) of FIG. 18 is information after update.

In the screen configuration definition information before update shown in FIG. 18A, the structural fragment ID “STR1001” of the screen configuration definition content 1102 is the structural fragment with the grid 1501 as the highest level, and the structural fragment ID of the screen configuration definition content 1103. “STR1002” is another structural fragment that is coupled to the parent structural fragment ID “STR1001” of the screen configuration definition content 1103 by the coupling point ID “LNK1001”.

In the updated screen configuration definition information shown in (b) of FIG. 18, the structure fragment ID “STR1003” added in the screen structure fragment dividing process is added to the screen configuration definition information. Along with this, the structural fragment that is coupled to the coupling point LNK1001 of the parent structural fragment ID “STR1001” is updated from “STR1002” to “STR1003”, and the coupling destination of the structural fragment ID “STR1002” is the structural fragment ID “STR1003”. Updated to join point LNK1001. Further, the structure fragment ID “STR1002” is added to the screen configuration definition information. Along with this, “STR1003” is added as a structural fragment that binds to the binding point LNK1001 of the parent structural fragment ID “STR1002”.

Next, the screen specification definition information reconfiguration unit 112 executes a screen specification definition process for the additional screen, and edits the screen specification definition information for the screen to be added (S1605). For example, in the example of the screen shown in FIG. 15, the screen structure fragment definition information storage unit 106 stores the screen structure fragment definition information related to the structure fragment having the grid 1507 as the structure fragment of the screen-specific portion of the screen to be added. The screen configuration definition information storage unit 107 stores screen configuration definition information such that the structural fragment having the grid 1507 as the highest level is combined with the connection point 1505 when the structural fragment having the grid 1501 as the highest level is divided.

That is, the screen specification definition information reconfiguration unit 112, based on information (information on the grid 1504) indicating the difference between the newly added screen and the common part of each screen, the screen structure fragment belonging to the common screen. Screen structure fragment definition information (screen structure fragment information related to the grid 1501) relating to a portion where the definition information can be diverted to a newly added screen, and a screen structure fragment relating to a difference between a newly added screen and a common portion of each screen It is divided into definition information (screen structure fragment information related to the grid 1504), and the screen structure fragment definition information related to a portion that can be diverted to a newly added screen is combined with the newly added screen-specific screen structure fragment definition information As a point, the screen configuration definition information related to the newly added screen is stored in the screen configuration definition information storage unit 107, and the existing common frame structure Configured automatically executes changes associated screen configuration definition information.

According to the present embodiment, when a frame structure common to each screen is already stored in the screen structure fragment definition information storage unit 106 as screen structure fragment definition information, a portion that does not partially match the frame structure common to each screen When it becomes necessary to add a new screen having a structure, it is possible to automatically change the screen configuration definition information related to the reconfiguration of the existing common frame structure.

For this reason, according to the present embodiment, the specification is not completely clear from the beginning as in an iterative development process, and even when a screen is added later, a development method in which the common range of the common frame is changed is also used. There is an advantage that rework for changing the screen specification definition information of the entire screen is unnecessary.

In addition, according to the present embodiment, when the specification of the structure common to the screen corresponding to the frame portion is defined and the common range of the frame portion needs to be changed, the common structure of the defined frame portion is changed. As the screen specification information related to the frame part can be updated at once, it is possible to update the screen at once, so even if the present invention is applied to an iterative development process, each screen when a common range change is required There is an advantage that reworking of the revision of the specification definition is unnecessary.

In the present invention, the screen program code generation unit 108 can also generate the screen program code as one program module for each screen, and the screen program code corresponding to the common portion of the screen into one module. It can also be generated as a common one. That is, the screen program code generation unit 108 can generate the screen program code by dividing it into a screen program code common to each screen and a screen program code unique to each screen. In the latter case, since the size of the screen program can be made smaller than that of the former, there is an advantage that the memory size when executing the screen program can be reduced.
