Description

  The present invention relates to a technique for supporting the development of software (or system), and more particularly to a technique for analyzing the influence of influences that occur when modifying design items.

  The system and software development process consists of a number of processes separated by each deliverable, starting with the creation of a requirement description document, creating a design model, and creating program code from the design model. . In creating this design model, there is Patent Document 1 as a background art in this technical field. In Patent Document 1, an environment for easily creating a requirement specification document in the form of assembling a template of a requirement specification document (scenario pattern) is realized, and when software design information is extracted from the requirement specification document, the software design included in the scenario pattern It is proposed to verify and manage the software screen configuration, screen transition, data, etc. in cooperation with the requirement specification document by using the adjustment variables of the above and the relationship information between scenario patterns.

JP 2007-257252 A

Conventional system development including Patent Document 1 has the following three problems from the viewpoint of design consistency.
First of all, there is a case where only the mounted product is changed when the design information is changed. Until now, when design information has changed, other design information affected by the design information and the designer have been notified verbally, by e-mail, and in writing. At that time, if the work has progressed to the creation of the implementation, it is possible to change the physical name represented by the variable name and deal with it. Since there was often a situation where only changes were made, there was a concern about the deterioration of design quality.

  Second, it is impossible to accurately grasp the influence range at the time of design change. Although it is possible for the designer to conduct the influence study on the influence of the design change in the design process, it is not certain from the viewpoint of completeness, and the selection of the impact notification destination, notification method, notification timing, etc. Therefore, design inconsistency is likely to occur, and it is difficult to ensure design quality.

  Thirdly, not all designers can investigate the range of influence at the time of design change. When the method call relationship is complicated, it becomes practically difficult for a designer other than the designer who is in charge of the design item to propagate the influence of the change information. Therefore, it is necessary to have a mechanism that allows each designer to grasp the influence spread part without omission.

  In order to solve the above-mentioned problems, the present invention uses design information related to software design and a design impact status that is a flag that suggests that the update of the design information may affect other design information. , To manage the impact caused by the design. Furthermore, in the present invention, the parent-child relationship between the caller method and the callee method and the design influence status are managed in association with each other, and when the design information is updated, the influence spread analysis of the design information is performed using these. This is also included as an aspect. Furthermore, a function of notifying the design terminal of a list of influence influence destination design information as the analysis result may be provided.

  According to the present invention, when there is a modification (change) by design, it is possible to manage the influence of the modification.

An embodiment of the present invention will be described below with reference to the drawings.
FIG. 1 is a block diagram showing the hardware of this embodiment and the configuration of the modules in the hardware, FIG. 2 is an overall work flowchart of the influence spread analysis support method in this embodiment, and FIG. It is a flowchart which shows the process sequence in the shown module. FIG. 4 is a data table used in a series of operations from the update of design information to the completion of re-update of design information in accordance with the result of influence influence analysis in the present embodiment.

  In FIG. 1, the influence spread analysis support method shown in the present embodiment has a design information spread analysis module 10.

  When the designer updates the design information from the design terminal and the design information table 12 is updated, the design information propagation analysis module 10 is affected by changing the design information using the design information link table 14. Extract and notify design information that may appear. 4 and 5 are examples of the data structure of each table in FIG. The relationship between the tables in FIGS. 4 and 5 will be described below.

  The “design information table” shown in FIG. 4 is a data configuration example of the design information table of FIG. Next, each item of the design information table will be described. The internal ID is a unique number for uniquely identifying each design information, and is assigned each time new design information is added. The method name represents the name of the method indicated by the design information. Used method 1 and used method 2 indicate names of other methods called by the design information. The influence status 250 has a value of “influence” when certain design information is updated and there is a possibility that the design information may be affected (need to be changed). If the designer reviews all design information in which the influence status 250 is “influenced” and the value “influenced” is not removed from the influence status 250 of all the design information, the consistency of the design information can be maintained. I can't say that. The version number 252 represents the number of times the design information is updated (design information is initially created as “1”), and is used for optimistic exclusive control when the designer updates the design information.

  Next, the “design information link table” shown in FIG. 5 is a data configuration example of the design information link table of FIG. Next, each item of the design information link table will be described. For the parent / internal ID and the child / internal ID, a number that exists as the internal ID of the design information table is assigned. When method A internally calls method B each time new design information is added, the internal ID of the calling method A is “parent / internal ID” and the internal ID of the calling method B is “child” “Internal ID” is stored in the design information link table as a pair. This makes it possible to clarify the parent-child relationship between which method a method is called from and which method a method is calling. The influence status 270 has a value of “influenced” when certain design information is updated and there is a possibility that the design information is affected (need to be changed). By adding this item to the design information link table, it is possible to associate which design information is updated to affect the design information. This item is used when the “influence influence information list screen” shown in FIG. 9 is displayed, and helps the designer understand the contents of the influence influence information. The design information link table has an ascending index with the field “parent / internal ID” and an ascending index with the field “child / internal ID” for the purpose of improving the processing speed when searching in the table. An ascending index with the field “Impact Status” is created.

  6, 7, 8, and 9 are screen views showing various screens displayed on the design terminal in FIG. 1. The relationship between the screen diagrams of FIGS. 6, 7, 8, and 9 will be described below.

  The “class list screen” shown in FIG. 6 is a screen 300 that displays a list of designed classes on the design terminal. The screen 300 includes a radio button 302 for selecting one class, a class name 304, a class Japanese name 306, class processing content 308, and a method list button 310. When the method list button 310 is pressed with one radio button 302 selected, the screen can be changed to a screen 400 that displays a method list in the class.

  Next, the “method list screen” shown in FIG. 7 is a screen 400 for displaying a list of designed methods in a certain class on the design terminal. The screen 400 includes a class name 402 to which the method belongs, a class Japanese name 404, class processing content 406, a radio button 408 for selecting one method, a method name 410, and a method Japanese name 412. , Method processing contents 414, influence status 416, and business call definition button 418. If the business call definition button 418 is pressed with one radio button 408 selected, the screen can be changed to a screen 500 that displays a call class name and a call method name in the method.

  Next, the “business call definition screen” shown in FIG. 8 is a screen 500 that displays a call class name and a call method name for a certain method. The screen 500 shows a class name 502 to which the method belongs, a method name 504, a radio button 506 for selecting one of the calling method names 510, a calling class name 508, a calling method name 510, and an influence status. 512, an update button 514, and a confirmation button 516. If the update button 514 is pressed while an item whose influence status 512 is “influenced” is selected with the radio button 506, the method may be affected by other design information updates. It is determined that the need for correction is recognized, and the design information can be corrected. As soon as the influence spread destination design information is updated, the influence status 512 is canceled (the value of the item is changed from “influenced” to “−”). In addition, when the confirmation button 516 is pressed while an item whose influence status 512 is “influenced” is selected with the radio button 506, there is a possibility that the method may be affected by other design information updates. The designer determines that there is no need for correction, and the influence status 512 is canceled (the value of the item is changed from “influenced” to “−”).

  In the current system, the class list screen 300, method list screen 400, business call definition screen 500, and the like described above are used in order to confirm and update the influence spread design information (items whose influence status 512 is “influenced”). You have to follow the screen in order. In this case, there are problems that it is difficult for the designer to grasp the total number of influence spreading design information and that it is difficult to check the influence spreading design information without omission. In order to solve this problem, the influence influence information list screen 600 is newly displayed on the design terminal.

  Next, the “influence influence information list screen” shown in FIG. 9 includes the design information (class name / method name) updated by the designer and the corresponding influence influence destination design information (class name / method name). It is a screen 600 for displaying a list. The screen 600 includes a radio button 602 for selecting one combination of update design information and influence influence destination design information, a class name 604 of update design information, a method name 606 of update design information, and influence influence destination design information. Class name 608, method name 610 of influence influence destination design information, influence influence information update button 612, and confirmation button 614. When the influence influence information update button 612 is pressed, an item whose influence status is “influenced” is extracted from the design information link table 14 shown in FIG. 1, and the latest influence propagation information is listed at that time. It is evaluated. When the confirmation button 614 is pressed in a state where the combination of the update design information and the influence destination design information is selected with the radio button 602, the business call definition screen 500 shown in FIG. The designer decides whether or not to make corrections.

Next, FIG. 2 shows an overall work flow of the influence spread analysis support method shown in the present embodiment.
First, the design information table 12 is updated according to the designer's instruction sent from the design screen on the design terminal 140. At that time, the system acquires the value of the version number 252 on the design information table 12 in advance, and resets the version number 252 by adding 1 to the value of the version number 252 acquired previously when the design information is updated. To do. Here, if the value of the version number 252 acquired in advance is different from the value of the version number 252 when the design information is updated (before resetting the version number 252), there is a possibility that the design information is inconsistent. Therefore, optimistic exclusion control is realized by discarding the update contents and notifying the designer terminal 140 of an error (step 100). When the update to the method name and the used method (one or more places) on the design information table 12 is completed, the processing is transferred to the design information propagation analysis module 10 of FIG. 1 (step 102). When it is detected that the influence spread information update button 612 on the influence spread information list screen 600 is pressed from the design terminal 140 (step 104), the influence status 270 is “influenced” from the design information link table 14. Extract design information.

  At this time, since an index is created for the “influence status” in the design information link table 14, a search process using this column as a key can be executed at high speed. In addition, there are only two types of data stored in this column: “Affected” and “-”, but the number of “Affected” is expected to be considerably smaller than “-”. Even when developing a large-scale system such as a mega bank in which the data stored in the design information link table 14 is enormous, when searching for an item whose value in this column is “influenced”, the search processing speed can be improved. It is considered effective to use the index from the viewpoint (step 106). As a result, if one or more pieces of influence spread information exist (step 108), the influence spread information is received from the design information link table 14 and the design information table 12 in a state where the influence spread information can be listed, and affects the design terminal 140. It is displayed as a spread information list screen 600 (step 110). When it is detected from the influence spread information list screen 600 on the design terminal 140 that one combination of the updated design information and the influence spread destination design information is selected and the confirmation button 614 is pressed (step 114), the influence spread destination is detected. A transition is made to the design information business call definition screen 500 (step 116). In the business call definition screen 500, it is detected which one of the update button 514 and the confirmation button 516 is pressed by the designer (step 118). When the update button 514 is pressed (design item needs to be updated), the radio button 506 is displayed. The design screen is displayed from the design terminal 140 with respect to the design information selected in (1), and the design information table 12 is updated in accordance with the instructions of the designer. Also in this case, the design information is updated using optimistic exclusion control as in step 100 (step 120).

  Next, when the update completion input to the method name and the used method (one or more places) on the design information table 12 is detected, the influence status of the design item in the design information table 12 and the design information link table 14 is canceled (influence). After the values of the status 250 and the influence status 270 are changed from “impact” to “−” (step 122), the processing is transferred to the design information propagation analysis module 10 of FIG. 1 (step 124). When the confirmation button 516 is pressed (the design item need not be updated), the influence status of the design item in the design information table 12 and the design information link table 14 is released (the values of the influence status 250 and the influence status 270 are “influenced”. "-" To "-"), it is confirmed that there is no influence on the design item (step 126). After a series of processing from step 114 to step 126 is performed for each display item on the influence spread information list screen 600 (step 112), the influence spread on the influence spread information list screen 600 from the design terminal 140 is performed. When it is detected that the information update button 612 has been pressed (step 104), the processing after step 106 is executed again. This is repeated until all the influence statuses are released (the values of the influence status 250 and the influence status 270 are changed from “influenced” to “−”) (step 108). By following the procedure as described above, even when new influence transmission information is generated as a result of the update of the influence influence design information, it is possible to capture the correction contents of the information without omission.

  Next, referring to FIG. 3, the operation from the start (step 200) to the end of the design information propagation analysis module 10 will be described.

  First, in order to check whether there is design information called from the changed design information, the internal ID of the changed design information is set as a key “parent / internal ID”, and the corresponding “child / internal Search for “ID”. At this time, since an index is created for the “parent / internal ID” in the design information link table 14, a search process using this column as a key can be executed at high speed. In addition, since the number of types of data stored in this column is very large, the search processing speed is improved even when developing a large-scale system such as a mega bank in which the number of data stored in the design information link table 14 is enormous. From this point of view, it is considered effective to use the index (step 202). It is determined whether or not “child / internal ID” corresponding to “parent / internal ID” exists (step 204). If “child / internal ID” exists (design information corresponding to “child / internal ID”) If there is another design information that calls ”, the impact status 250 on the design information table 12 and the impact status 270 on the design information link table 14 are set to“ − ”for the design information of the“ parent / internal ID ”. To "influenced" (step 206). Similarly, in order to check whether there is design information calling the changed design information, the internal ID of the changed design information is set as a key “child / internal ID”, and the corresponding “ Search for “parent / internal ID”. At this time, since an index is created for the “child / internal ID” in the design information link table 14, the search process using this column as a key can be executed at high speed. In addition, since the number of types of data stored in this column is very large, it is considered effective to use an index from the viewpoint of improving the search processing speed (step 208).

It is determined whether “parent / internal ID” corresponding to “child / internal ID” exists (step 210). If “parent / internal ID” exists (design information corresponding to “parent / internal ID”) If there is another design information that calls ”, the impact status 250 on the design information table 12 and the impact status 270 on the design information link table 14 are set to“ − ”for the design information of the“ child / internal ID ”. To "affected" (step 212)
According to the above embodiment, the design information is provided when the design information is updated by providing the design information spreading analysis function having the design information link table and the design information link table. It is possible to investigate the method being called and the method being called from the design information, and specify the influence spread point.
In addition, by notifying the designer of a list of inconsistent design information through the designer terminal, the designer can accurately grasp the inconsistent design information without omission and keep the design information as a whole consistent. Is possible.

  Furthermore, when an update of certain design information spreads to related design information, and the design information of the influence spread destination is modified, a new influence spread may occur due to the update of the design information. Each time a design item determined to be corrected is corrected, a list of the latest inconsistent design information is displayed on the designer terminal, so that it is possible to prevent inconsistencies in design information due to oversight of the designer.
