[0002]
In particular, the present invention relates to a software code generation device and a software code generation method that can easily cope with a change in specifications such as a logic module configuration (system configuration) and a mounting method (mounting language, operation system, etc.).
[0003]
[Prior art]
2. Description of the Related Art Conventionally, there is a software code generation device that automatically generates software code according to specifications created by a developer or user.

[Problems to be solved by the invention]
However, the techniques described in Patent Document 1 and Patent Document 2 have the following problems.
[0009]
The first problem is that it cannot easily cope with changes in mounting technology. Hereinafter, the reason for this first problem will be described.
[0010]
For example, there is a case where there is no change in the business specification and the logical module configuration specification, and only the mounting specification, that is, the mounting language, the OS (operating system), etc. are changed.
[0011]
When the above changes occur, the technology described in Patent Document 1 creates a specification that describes the changed operation specifications and the business specifications and logic module configuration specifications that have not been changed, The software code had to be generated anew based on this new specification.
[0012]
In the technique described in Patent Document 2, although a model is separated into a part that depends on the mounting technique and a part that does not depend on the mounting technique, separation as a tool or a code generation mechanism is not performed.
[0013]
Therefore, when the above changes occur, only the part that depends on the mounting technology needs to be changed as a model, but since no separation is performed as a tool or code generation mechanism, software code is actually generated At that time, the same processing as in Patent Document 1 had to be performed.
[0014]
The second problem is that it cannot easily cope with changes in business functions (business specifications). Hereinafter, the reason for this second problem will be described.
[0015]
For example, there is a case where there is no change in the logical module configuration specification and the mounting specification, and only the business function is changed in the middle.
[0016]
In the above case, the technique described in Patent Document 1 creates a new specification that includes the changed business functions (business specifications) and the logical module configuration specifications and mounting specifications that have not been changed. The software code had to be generated anew based on the specification.
[0017]
Although the technique described in Patent Document 2 is separated as a model into a part that depends on the mounting technique and a part that does not depend on the mounting technique, it is not separated as a tool or code generation mechanism. If there is a major change, it is only necessary to change the part that does not depend on the mounting technology as a model, but since no separation is performed as a tool or code generation mechanism, when actually generating software code, The same processing as in Patent Document 1 had to be performed.
[0018]
The third problem is that human resources who need high skills are required for development of software code generation.
[0019]
The reason for the above is that, in the techniques described in Patent Document 1 and Patent Document 2, since the part for performing the conversion process is not separated, appropriate development sharing cannot be performed, and the developer has knowledge of business and implementation technology. This is because it is necessary to have both.
[0020]
An object of the present invention is to provide a software code generation apparatus and a software code generation method that can easily cope with changes in specifications such as mounting technology specifications.

[0082]
Next, the operation of the present embodiment will be described in detail with reference to FIG.
[0083]
A user or a developer creates or modifies a business specification of a business system to be developed by operating the business specification editing unit 1.
[0084]
Here, for example, in the case of a business system using a GUI screen, the business specification describes the type of screen, transition between screens, display information on each screen, user input information, and the like. The system requirements (required specifications) are described in a form independent of the realization method, ie, the realization specification.
[0085]
FIG. 2 shows a specific example of the business specification. The business specification can be described in an XML (extensible Markup Language) format or the like as shown in FIG.
[0086]
The business specification created using the business specification editing unit 1 is stored in the business specification storage unit 2 by the business specification editing unit 1.
[0087]
Further, the user operates the design decision information editing means 5 to determine the realization method of how to realize the business system to be developed, that is, the realization specification, and the decided realization specification is determined as the design decision information. And Specific examples of the design determination information include information such as the above-described logic module configuration specifications and mounting specifications. The implementation specifications include information on operating system specifications and implementation language specifications.
[0088]
FIG. 3 shows a specific example of the design decision information. The design decision information can be described in the XML format or the like as shown in FIG.
[0089]
In FIG. 3, the logical module configuration specification is indicated by a logical architecture element, and the implementation specification is indicated by an implementation method element. More specifically, as the mounting specifications, two specifications of an operating system specification and a mounting language specification for each logical module (module name) are indicated by a mounting OS element and a mounting language element, respectively.
[0090]
As described above, when the user or developer operates the design decision information editing unit 5, the type of conversion rule stored in the upper conversion rule storage unit 3 and the lower conversion rule storage unit 4 is displayed. It can be referred to by the display of the part 5a.
[0091]
Therefore, whether or not the conversion rule corresponding to the required specification including the design option, that is, the business specification and the realization specification exists in the upper conversion rule storage unit 3 and the lower conversion rule storage unit 4, that is, the code from the business specification It is possible to determine whether the generation is possible.
[0092]
As a reference method, all types of conversion rules stored in the upper conversion rule storage unit 3 and the lower conversion rule storage unit 4 may be displayed on the display unit 5a, or the design judgment information editing unit 5 Information indicating whether or not the change rule specified in (1) exists may be displayed on the display unit 5a.
[0093]
The design judgment information created using the design judgment information editing means 5 is stored in the design judgment information storage means 6 by the design judgment information editing means 5.
[0094]
The business specification stored in the business specification storage unit 2 is converted into an intermediate format by the business specification conversion unit 7.
[0095]
The conversion by the business specification conversion means 7 is selected from a plurality of types of first conversion rules stored in the upper conversion rule storage means 3 based on the design determination information, more specifically, based on the design determination information and the business specifications. The business specification is converted into an intermediate format using the first conversion rule.
[0096]
For example, if the business specification or the intermediate format is an XML format, the first conversion rule is described as a template, such as XSLT (extensible stylesheet transformation), or Java (registered trademark) in which conversion logic is described. Can be realized as a class.
[0097]
Which conversion rule the business specification conversion means 7 selects from among a plurality of types of first conversion rules stored in the higher-order conversion rule storage means 3 is the specification of the logical architecture described in the design decision information, that is, Refer to the logic module configuration specification. Furthermore, the selection by the business specification conversion means 7 is performed based on the logical module configuration specification and the business specifications edited by the business specification editing means.
[0098]
For example, when the logical module configuration is a client-server configuration, there are roughly divided system modules on the client side and system modules on the server side, and it is necessary to divide the business specifications into each module and select a conversion rule for mapping There is.
[0099]
That is, the business specification conversion unit 7 selects a conversion rule corresponding to the logical module configuration specification from a plurality of types of first conversion rules stored in the upper conversion rule storage unit 3. Furthermore, the business specification conversion unit 7 selects a conversion rule corresponding to the logical module configuration specification and the business specification from among a plurality of types of first conversion rules stored in the upper conversion rule storage unit 3.
[0100]
The business specification conversion unit 7 executes the selected conversion rule to generate an intermediate format, and stores the generated intermediate format in the intermediate format storage unit 8.
[0101]
Here, the intermediate format will be explained again. What is the logical module configuration in a format that is independent of the implementation specifications of the implementation language, OS, middleware, etc., and what attributes and processing each logical module is responsible for? Is described.
[0102]
FIG. 4 shows a specific example of the intermediate format. The intermediate format can be described in the XML format or the like as shown in FIG.
[0103]
The intermediate format stored in the intermediate format storage unit 8 is converted into a target software code by the intermediate format conversion unit 9 and stored in the code storage unit 10.
[0104]
The conversion by the intermediate format conversion means 9 is a conversion that executes the second conversion rule selected from the plurality of types of second conversion rules stored in the lower conversion rule storage means 4 based on the design judgment information. is there. The second conversion rule can be realized in the same manner as the first conversion rule.
[0105]
Which conversion rule the intermediate format conversion means 9 selects from among a plurality of types of second conversion rules stored in the lower conversion rule storage means 4 depends on the mounting method described in the design decision information, that is, the mounting specification. Refer to the specification.
[0106]
For example, the client side uses a first language (for example, Visual Basic (registered trademark)) on a first OS (for example, Windows (registered trademark)), and the server side is different from the first OS. When realizing each using a second language (for example, Java (registered trademark)) different from the first language on the OS (for example, Linux), software code suitable for each mounting method is generated. It is necessary to select a conversion rule for.
[0107]
In this embodiment, as described above, automatic generation of software code is performed by multi-stage conversion processing by a plurality of conversion means, and the conversion rule of each conversion processing is the first conversion rule (first 1 conversion rule) and a second conversion rule (second conversion rule) depending on the mounting specification.
[0108]
Therefore, the intermediate format generated by the first conversion rule and stored in the intermediate format storage unit 8 can be reflected in various implementation specifications by designating various implementation specifications by the design judgment information editing unit 5. Improves versatility.
[0109]
In addition, since each of the plurality of conversion means performs conversion according to the corresponding specification, it is possible to easily cope with a change in the specification. In addition, when the changed specification cannot be converted, only the conversion corresponding to the changed specification needs to be developed, so that the change of the specification can be easily handled.
[0110]
In addition, by designating various logic module configuration specifications by the design judgment information editing means 5, the business specifications can be converted into an intermediate format reflecting various logic module configuration specifications, so the versatility of the business specifications is improved.
[0111]
Further, when only the implementation specification changes with respect to the original requirement specification, the design specification information editing means 5 does not change the intermediate format already developed based on the first conversion rule, but the changed implementation specification. By newly designating, it becomes possible to generate software code according to a new implementation specification.
[0112]
That is, it is possible to simplify the conversion process without performing the conversion process again on the specification without change, and it is possible to easily cope with a change in mounting technology.
[0113]
Even if the second conversion means does not have the second conversion rule corresponding to the desired mounting specification, only the conversion rule corresponding to the mounting specification needs to be additionally developed. Conversion rules need not be changed, and it becomes easier to respond to changes in mounting specifications.
[0114]
Further, it becomes possible to easily cope with addition of business specifications or change of logical module configuration specifications. The reason is that when a business specification is added or when a logical module configuration specification is changed, only the first conversion rule corresponding to these needs to be added or changed. Therefore, it is possible to easily cope with the addition of business specifications and the change of logical module configuration specifications.
[0115]
In addition, in the development of software code generation technology, development efficiency can be improved because the development sharing according to the skill of the developer can be easily performed. The reason for this is that the first conversion rule that requires business specifications, that is, business knowledge, and the second conversion rule that requires implementation knowledge are independent. This is because.
[0116]
Further, since the upper conversion rule storage means 3 stores a plurality of types of first conversion rules, it is possible to cope with different logic module configuration specifications, and the versatility of software code generation is improved.
[0117]
Further, since the lower conversion rule storage means 4 stores a plurality of types of second conversion rules, it is possible to cope with different mounting specifications, and the versatility of software code generation is improved.
[0118]
(Example 2)
Next, another example (Example 2) of the embodiment of the present invention will be described in detail with reference to the drawings.
[0119]
FIG. 5 is a block diagram illustrating a software code generation system, that is, a software code generation apparatus according to the second embodiment. In FIG. 5, the same components or functions as those in FIG.
[0120]
In FIG. 5, the first lower-order conversion rule storage unit 41 converts a plurality of types of intermediate formats stored in the intermediate format storage unit 8 into second intermediate formats associated with functions provided by the OS. The third conversion rule is stored. Each of the plurality of types of third conversion rules converts the intermediate format into one of a plurality of types of second intermediate formats corresponding to different OS specifications.
[0121]
The intermediate format conversion unit 91 extracts OS-only information, that is, the operating system specification from the design determination information, and stores the third conversion rule corresponding to the extracted operating system specification in the first lower conversion rule storage unit 41. The third conversion rule is selected from the plurality of types of third conversion rules.
[0122]
When the third conversion rule is selected, the intermediate format conversion unit 91 associates the intermediate format with the function provided by the OS described in the extracted operating system specification based on the third conversion rule. The second intermediate format is converted into the second intermediate format, and the second intermediate format is stored in the intermediate format storage unit 81.
[0123]
The second lower conversion rule storage means 42 stores a plurality of types of fourth conversion rules for converting the second intermediate format stored in the intermediate format storage means 81 into software code. Each of the plurality of types of fourth conversion rules converts the second intermediate format into one of a plurality of types of software codes corresponding to different implementation languages.
[0124]
The intermediate format conversion unit 92 extracts the implementation language information, that is, the implementation language specification from the design determination information, and stores the fourth conversion rule corresponding to the extracted implementation language specification in the second lower conversion rule storage unit 42. The fourth conversion rule is selected from the plurality of types of fourth conversion rules.
[0125]
When the fourth conversion rule is selected, the intermediate format conversion unit 92 converts the second intermediate format into a target software code based on the fourth conversion rule and stores it in the code storage unit 10.
[0126]
That is, in the second embodiment shown in FIG. 5, there are two intermediate format storage means, intermediate format conversion means, and lower-order conversion rule storage means, respectively, and software code generation is performed by performing three stages of conversion processing as a whole. Is going.
[0127]
Therefore, according to the second embodiment, when the OS is unchanged and only the implementation language is changed, for example, the first OS is continuously used, but the language is different from the first language to the first language. When the change is made to the second language, the changed implementation is stored in the intermediate format storage means 8 or the intermediate format storage means 81 without changing the already developed intermediate format and the second intermediate format. It is possible to cope by changing only the conversion rule corresponding to the language, and the influence range of the conversion rule change accompanying the specification change can be reduced.
[0128]
The display unit 5a includes the first conversion rule stored in the upper conversion rule storage means 3, the third conversion rule stored in the first lower conversion rule storage means 41, and the second lower conversion rule. The fourth conversion rule stored in the storage means 42 is displayed.
[0129]
Therefore, the user can determine whether or not the first, third and fourth conversion rules corresponding to the required specifications exist, that is, whether or not the software code corresponding to the required specifications can be generated by the display on the display unit 5a. Can be determined.
[0130]
Since this embodiment (embodiment 2) includes the third and fourth conversion means, even when only one of the operating system specification and the implementation language specification is changed from the original requirement specification, there is no change. It is not necessary to perform a conversion operation according to other specifications, and it becomes possible to easily cope with changes in operating system specifications or implementation language specifications.
[0131]
Further, according to the operating system specification edited by the design decision information editing means from among a plurality of third conversion rules for converting the intermediate format into a plurality of types of second intermediate formats corresponding to different operating system specifications. The third conversion rule is selected as the third conversion rule, and the intermediate format is converted into the second intermediate format according to the selected third conversion rule, so that it is possible to cope with different operating system specifications, and the software code generation device Improves versatility.
[0132]
Further, according to the implementation language specification edited by the design judgment information editing means from among a plurality of fourth conversion rules for converting the second intermediate format into a plurality of types of software codes corresponding to different implementation language specifications. The fourth conversion rule is selected as the fourth conversion rule, and the second intermediate format is converted into the software code according to the selected fourth conversion rule. Improves versatility.
[0133]
In the above, an example in which the conversion process is divided into two stages or three stages has been described. However, for example, there are three or more types of specifications included in the implementation specifications that are input or changed using the design decision information editing unit. In some cases, each intermediate format conversion means has each specification by providing as many lower conversion rule storage means, intermediate format conversion means, and intermediate format storage means that store conversion rules as the number of types of the above specifications. It is possible to take charge of the conversion process according to the above, and a configuration having a multi-stage conversion process can be realized.
[0134]
As described above, since each conversion unit is responsible for the conversion process corresponding to each specification, it is possible to easily cope with a change in mounting specifications. That is, by selecting a conversion process corresponding to the changed specification and executing the selected conversion process, it becomes easy to cope with the change of the specification.
[0135]
In each of the embodiments described above, the illustrated configuration is merely an example, and the present invention is not limited to the configuration.
[0136]
Another object of the present invention is to supply a recording medium in which a program code of software that realizes the functions of the above-described embodiments is recorded to a system or apparatus including a computer, and the computer stores the program code stored in the recording medium. Needless to say, this can also be achieved by reading and executing.
[0137]
In the above case, the program code itself realizes the function of the above-described embodiment, and the program and the recording medium on which the program code is recorded constitute the present invention.
[0138]
【The invention's effect】
According to the present invention, it is possible to easily cope with changes in mounting specifications. That is, for example, when a change occurs only in the implementation specification with respect to the initial requirement specification, the design decision information editing means is generated without changing the intermediate format already generated by the first conversion means and stored in the storage means. Thus, since the software code corresponding to the new mounting specification can be generated by designating the changed mounting specification, it is possible to easily cope with a change in the mounting specification.
[0139]
In other words, it is possible to avoid performing the same conversion operation again for the business specifications and logic module configuration specifications that are not changed.
[0140]
Even if the second conversion means does not have the second conversion rule corresponding to the desired mounting specification, only the conversion rule corresponding to the mounting specification needs to be additionally developed. Since it is not necessary to change the first conversion rule, it is easy to cope with changes in the mounting specifications.
[0141]
In addition, by specifying various mounting specifications by the design judgment information editing means, one intermediate format can be reflected in various mounting specifications, so that the versatility of the intermediate format is improved.
[0142]
Further, according to the above invention, it is possible to easily cope with addition of business specifications or change of logic module configuration specifications. The reason is that when a business specification is added or when a logical module configuration specification is changed, only the first conversion rule corresponding to these needs to be added or changed. Therefore, it is possible to easily cope with the addition of business specifications and the change of logical module configuration specifications.
[0143]
Further, according to the above-described invention, in the development of the software code generation device, the development assignment according to the skill of the developer can be easily performed, and the development efficiency is improved. The reason for this is that the first conversion rule that requires business specifications, that is, business knowledge, and the second conversion rule that requires implementation knowledge are independent. This is because.
[0144]
In addition, since each of the plurality of conversion means performs conversion according to the corresponding specification, it is possible to easily cope with a change in the specification. In addition, when the changed specification cannot be converted, only the conversion corresponding to the changed specification needs to be developed, so that the specification can be easily changed.
