Hereinafter, a specification generation device and a specification generation system according to an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a block diagram illustrating an example of a specification generation system 100 according to the present embodiment.
As shown in this figure, the specification generation system 100 includes a specification generation device 1 and a file server device 30. The specification generation device 1 and the file server device 30 are connected via a network, for example.

  The file server device 30 is, for example, a server device including a storage device, and stores a source file and a setting file that are input information of the specification generation device 1 and a design document that is output information of the specification generation device 1. The file server device 30 includes a source file storage unit 31, a setting file storage unit 32, and a design document storage unit 33.

  The source file storage unit 31 (an example of a source storage unit) stores, for example, a source file for generating a design document, which is a source file of an existing system program. Note that the source file storage unit 31 may store a plurality of source files in advance. The source file storage unit 31 stores, for example, a source file as shown in FIG.

FIG. 2 is a diagram illustrating an example of data in the source file storage unit 31 in the present embodiment.
In the example shown in this figure, the source code (SC1) of the program for calculating the purchase price is shown. In the source code SC1, the storage variables (first variables) for storing the processing results are “PRICE” and “ERR”, and this program is the number of purchases (“NUM”) and the product is alcohol (“AFLG”). "), The computer is caused to perform an input check as to whether the age is over 20 years old. In the source code SC1, the program causes the computer to execute a business process for outputting the total amount when the above-described input check condition is satisfied. Thus, in the source code (SC1), the input check process corresponding to the input check and the business process are mixed. Here, the input check process is, for example, a process of checking whether or not an input value falls within a possible range in terms of specifications. The business process is, for example, a process executed by a program in order to achieve a predetermined purpose (for example, a business purpose).

  Returning to the description of FIG. 1, the setting file storage unit 32 stores a setting file for setting an error code storage variable (second variable) for storing the processing result of the input check. Here, the error code storage variable is set in advance after the user confirms the contents of the source code, for example. The error code storage variable (second variable) is a part of the storage variable (first variable), and the storage variable (first variable) includes an error code storage variable (second variable). Variable). As illustrated in FIG. 3, the setting file storage unit 32 associates the error code storage variable and a value indicating the success of the input check and stores them as a setting file.

FIG. 3 is a diagram illustrating an example of data in the setting file storage unit 32 in the present embodiment.
In the example shown in this figure, a setting file (EV1) is shown. In this example, the setting file storage unit 32 stores the error code storage variable “ERR” and the value “00” indicating the success of the input check in association with each other as a setting file (EV1).

  Returning to the description of FIG. 1 again, the design document storage unit 33 stores a design document that is output information (output result) of the specification generation device 1. Since the specification generation device 1 generates an input check design document and a business process design document from the source code, the design document storage unit 33 stores the input check design document and the business process design document. Here, the input check design document is a design document describing a design specification related to the input check. The business process design document is a design document describing design specifications related to business processes. When a plurality of source files are input to the specification generation device 1, the design document storage unit 33 may store a plurality of input check design documents and a plurality of business process design documents. Here, an example of the input check design document and the business process design document will be described with reference to FIGS. 4 and 5. The input check design document and the business process design document shown in FIGS. 4 and 5 are examples when the specification generation device 1 generates the source code (SC1) shown in FIG. 2 described above.

FIG. 4 is a diagram showing an example of the input check design document in the present embodiment.
As shown in this figure, the input check design document includes, for example, information that associates “NO.”, “Input check content”, and “error code”. Here, “NO.” Indicates an input check number, and “input check content” indicates a check condition (logical expression) that is the content of the input check. “Error code” indicates the value of an error code storage variable. Note that the input check design document of this embodiment does not include “input check content” and “error code” when the input check is successful.
In the example shown in FIG. 4, for example, the specification of the input check with “NO” being “1” is “NUM <1 || NUM> 99” for “input check content” and “E1” for “error code”. ".

FIG. 5 is a diagram showing an example of a business process design document in the present embodiment.
As shown in this figure, the business process design document includes, for example, information that associates “variable names”, “update contents”, and “conditions”. Here, “variable name” indicates the name of a storage variable that stores the processing result, and “update content” indicates content that is updated as a value of the variable. “Condition” indicates a condition for updating the variable. In the business process design document of this embodiment, it is assumed that the input check has been successful, and the conditions for the successful input check are not described.
In the example shown in FIG. 5, for example, a business specification whose “variable name” is “PRICE” indicates that “update content” is “PROD.PRICE * NUM” and “condition” is “always satisfied”. ing.

Returning to the description of FIG. 1 again, the specification generation device 1 includes a storage unit 10 and a control unit 20.
The storage unit 10 stores various information used by the specification generation device 1. The storage unit 10 includes, for example, an intermediate data storage unit 11, a divided intermediate data storage unit 12, and a simplified intermediate data storage unit 13.

  The intermediate data storage unit 11 stores intermediate data (sometimes referred to as an intermediate decision table) generated by an intermediate data generation unit 21 described later using a symbol execution technique. Here, as shown in FIG. 6, the intermediate data includes information in which a storage variable (first variable), a logical expression expressed by an input variable, and a value of the storage variable are associated with each other.

FIG. 6 is a diagram illustrating an example of intermediate data in the present embodiment.
In the example shown in this figure, intermediate data (DT1) generated based on the source code (SC1) shown in FIG. 2 described above is shown. In this example, the storage variables (first variables) are “PRICE” and “ERR”, and for each of these variables, the logical expression expressed by the input variable is associated with the value of the storage variable.

  Returning to the description of FIG. 1 again, the divided intermediate data storage unit 12 stores the divided intermediate data divided (separated) based on the error code storage variable by the division processing unit 22 described later. Note that the divided intermediate data includes input intermediate data indicating a processing portion corresponding to the input check and business intermediate data indicating a business processing portion not including the processing portion corresponding to the input check. Here, an example of input intermediate data and business intermediate data will be described with reference to FIGS. 7 and 8. Note that the input intermediate data and business intermediate data shown in FIGS. 7 and 8 are examples when the intermediate data (DT1) shown in FIG. 6 is divided.

FIG. 7 is a diagram illustrating an example of the input intermediate data in the present embodiment.
In this figure, the input intermediate data (SDT1) is data obtained by dividing (separating) the processing portion corresponding to the input check of the intermediate data (DT1) shown in FIG. As shown in this figure, it includes a logical expression corresponding to an error code storage variable (for example, “ERR”) and the value of the error code storage variable.

FIG. 8 is a diagram showing an example of business intermediate data in the present embodiment.
In this figure, business intermediate data (SDT2) is data obtained by dividing (separating) the processing portion corresponding to the business processing of the intermediate data (DT1) shown in FIG. As shown in this figure, a logical expression corresponding to a storage variable (for example, “PRICE”) that stores the result of the business process and the value of the storage variable are included.

  Returning to the description of FIG. 1 again, the simplified intermediate data storage unit 13 stores the intermediate data simplified by deleting unnecessary logical expressions by the simplification processing unit 23 described later. The simplified intermediate data includes simplified input intermediate data and simplified business intermediate data. Here, an example of simplified input intermediate data and simplified business intermediate data will be described with reference to FIGS. 9 and 10. Details of the process for simplifying the intermediate data (simplification process) will be described later.

FIG. 9 is a diagram illustrating an example of simplified input intermediate data in the present embodiment.
In this figure, simplified input intermediate data (SDT3) is data obtained by simplifying the input intermediate data (SDT1) shown in FIG. As shown in this figure, the simplified input intermediate data (SDT3) is input intermediate data from which unnecessary logical expressions are deleted by a predetermined algorithm described later.

FIG. 10 is a diagram illustrating an example of simplified business intermediate data according to the present embodiment.
In this figure, simplified business intermediate data (SDT4) is data obtained by simplifying the business intermediate data (SDT2) shown in FIG. As shown in this figure, the simplified business intermediate data (SDT4) is business intermediate data from which unnecessary logical expressions are deleted by a predetermined algorithm described later.

  Returning to the description of FIG. 1 again, the control unit 20 is a processor including, for example, a CPU (Central Processing Unit) and the like, and comprehensively controls the specification generation device 1. The control unit 20 includes, for example, an intermediate data generation unit 21, a division processing unit 22, a simplification processing unit 23, and a design document generation unit 24.

  The intermediate data generation unit 21 acquires the source code described in the source file from the source file storage unit 31 of the file server device 30. The intermediate data generation unit 21 parses the acquired source code and generates intermediate data using a symbol execution technique. For example, the intermediate data generation unit 21 generates intermediate data (for example, see FIG. 6) in which a storage variable (first variable), a logical expression expressed by an input variable, and a value of the storage variable are associated with each other. To do. Here, the symbol execution technique refers to a constraint condition using a pair of a variable and a corresponding constraint condition (logical expression) instead of executing a program while substituting ordinary specific values for the variable. It is a technology that performs simulation while updating (logical formula).

By using symbol execution technology, the intermediate data generation unit 21 can handle all ranges of values that can be taken by variables, not individual values, collectively through constraint conditions (logical expressions). In the data, intermediate variables other than the storage variable for storing the processing result can be deleted.
The intermediate data generation unit 21 includes a syntax analysis unit 211 and a symbol execution unit 212.

The syntax analysis unit 211 performs syntax analysis on the source code acquired from the source file storage unit 31.
The symbol execution unit 212 generates the intermediate data as shown in FIG. 6 described above using a symbol execution technique based on the analysis result analyzed by the syntax analysis unit 211. The symbol execution unit 212 stores the generated intermediate data in the intermediate data storage unit 11.

  The division processing unit 22 divides the above-described intermediate data into input intermediate data and business intermediate data based on an error code storage variable designated in advance. For example, the division processing unit 22 acquires a setting file (for example, see FIG. 3) from the setting file storage unit 32 of the file server device 30. The division processing unit 22 converts the intermediate data stored in the intermediate data storage unit 11 based on the error code storage variable specified by the acquired setting file into the input intermediate data as shown in FIG. The data is divided (separated) into business intermediate data as shown in FIG. That is, for example, the division processing unit 22 extracts a portion including the error code storage variable from the intermediate data and separates it as input intermediate data. For example, the division processing unit 22 extracts a portion that does not include the error code storage variable from the intermediate data, and separates it as business intermediate data. The division processing unit 22 stores the divided (separated) input intermediate data and business intermediate data in the divided intermediate data storage unit 12.

The simplification processing unit 23 is unnecessary from the business intermediate data based on the logical expression corresponding to the value of the error code storage variable when the input check is successful among the values of the error code storage variable included in the input intermediate data. Simple business intermediate data is generated by deleting simple logical expressions. In addition, the simplification processing unit 23 deletes unnecessary logical expressions from the input intermediate data based on a predetermined algorithm, and generates simplified input intermediate data.
The simplification processing unit 23 includes an input specification generation unit 231 and a business specification generation unit 232.

  The input specification generation unit 231 generates simplified input intermediate data based on a predetermined algorithm. That is, the input specification generation unit 231 deletes unnecessary logical expressions from the input intermediate data, for example, using the following two methods, and generates simplified input intermediate data.

(First method)
The input specification generation unit 231 deletes redundant logical expressions included in the input intermediate data based on logical expressions (for example, “X == 1 and X == 2”, etc.) that are false conditions. For example, when attention is paid to a logical expression “X == 1 and X == 2” that is a false condition, a logical expression that is negative (NOT) of one of the logical expressions that are false conditions is “X” == 1 and X! = 2 ”,“ X! = 2 ”is a redundant logical expression. In this case, the input specification generation unit 231 executes a simplification process by deleting the redundant logical expression “X! = 2” and setting “X == 1”.
It is assumed that the logical expression serving as the false condition is extracted, for example, in the process executed by the symbol execution unit 212 described above. The input specification generation unit 231 extracts a logical expression in which one of the logical expressions that are the false conditions extracted by the symbol execution unit 212 is negative (NOT), for example, from the input intermediate data. The input specification generation unit 231 deletes a redundant logical expression part in the logical expression.

(Second method)
In the input specification generation unit 231, the simplification processing unit 23 deletes the already described logical expression based on the description order of the value of the error code storage variable. The second method is a method of paying attention to the description order and deleting check conditions that have already been described (appeared) as checked (described). For example, consider the case where the order of input checks is as follows.

(1) If “X! = 1 and X! = 2”, the error code storage variable “ERR” is “E3”.
(2) If “(X == 1 or X == 2) and P == 1”, the error code storage variable “ERR” is “E2”.

In this case, since the logical expression “(X == 1 or X == 2)” in (2) is already described, the input specification generation unit 231 uses the logical expression “(X = = 1 or X == 2) "is deleted. In this way, the input specification generation unit 231 deletes a logical expression obtained by logically inverting a logical expression that has already been described as a logical expression that has already been described. That is, the input specification generation unit 231 deletes a logical expression that does not need to be described based on the logical expression already described according to the description order of the value of the error code storage variable.
In the present embodiment, the input specification generation unit 231 executes the simplification process by the (second method) based on the decision tree. Details of the simplification process according to this embodiment will be described later.

  In this way, the input specification generation unit 231 uses the above-described (first method) or (second method) to delete unnecessary logical expressions from the input intermediate data, as shown in FIG. Generate simplified input intermediate data. Here, the input specification generation unit 231 may delete an unnecessary logical expression from the input intermediate data by using any one of the above-described (first method) and (second method). However, an unnecessary logical expression may be deleted from the input intermediate data by using both (first method) and (second method). The input specification generation unit 231 stores the generated simplified input intermediate data in the simplified intermediate data storage unit 13.

  Based on the logical expression corresponding to the value of the error code storage variable when the input check described above is successful, the business specification generation unit 232 deletes unnecessary logical expressions from the intermediate business data, thereby simplifying the business Generate intermediate data.

  For example, in the example of the input intermediate data shown in FIG. 7, the value of the error code storage variable when the input check is successful is when “ERR” is “00”. In this case, the logical expression corresponding to the value of the error code storage variable is “(AGE> = 20 || PROD.AFLG! = 1) && NUM> = 1 && NUM <= 99”. The business specification generation unit 232 uses, for example, the above-described (second method) to calculate the logical expression “(AGE> = 20 || PROD.AFLG! = 1) && NUM> = 1 and && NUM <= 99”. Based on, delete as unnecessary logical expression. The business specification generation unit 232 first constructs a decision tree of a storage variable “PRICE” corresponding to a storage variable other than the error code storage variable “ERR”. The business specification generation unit 232 then creates a logical expression “NUM <1” that is a negative (NOT) of the logical expression “(AGE> = 20 || PROD.AFLG! = 1) && NUM> = 1 && NUM <= 99”. || NUM> 99 || (AGE <20 && PROD.AFLG = 1) ". The business specification generation unit 232 deletes unnecessary logical expressions from the business intermediate data by using the constructed decision tree and a logical expression that is negative (NOT) when the input check is successful. To do.

As a result, the business specification generation unit 232 generates simplified business intermediate data as shown in FIG. Note that, in the simplification process of the business intermediate data, the business specification generation unit 232 details the process of simplifying the business intermediate data based on the decision tree. The business specification generation unit 232 stores the generated simplified business intermediate data in the simplified intermediate data storage unit 13.
The business specification generation unit 232 uses not only the (second method) described above but also the (first method) in the simplification processing of the business intermediate data, and uses the (first method) to generate unnecessary logical expressions from the business intermediate data. It may be deleted. In other words, the business specification generation unit 232 uses one of the above-described (first technique) and (second technique) in the simplification process of the business intermediate data, and is unnecessary from the business intermediate data. The logical expressions may be deleted, or unnecessary logical expressions may be deleted from the business intermediate data by using both (first method) and (second method).

  The design document generator 24 generates an input check design document as shown in FIG. 4 based on the simplified input intermediate data. Further, the design document generation unit 24 generates a business process design document as shown in FIG. 5 based on the simplified business intermediate data. The design document generation unit 24 outputs the generated input check design document and business process design document to the file server device 30, and stores the input check design document and business process design document in the design document storage unit 33. The design document generation unit 24 includes an input specification shaping unit 241 and a business specification shaping unit 242.

Based on the simplified input intermediate data, the input specification shaping unit 241 generates an input check design document describing a design specification related to input check.
Since the simplified input intermediate data is generated based on the input intermediate data divided by the division processing unit 22, the input specification shaping unit 241 has the input intermediate data divided by the division processing unit 22. An input check design document may be generated based on the data.

Based on the simplified business intermediate data, the business specification shaping unit 242 generates a business process design document that describes design specifications related to business processes.
Since the simplified business intermediate data is generated based on the business intermediate data divided by the division processing unit 22, the business specification shaping unit 242 has the business intermediate data divided by the division processing unit 22. A business process design document may be generated based on the data.

Next, the operation of the specification generation device 1 according to the present embodiment will be described with reference to the drawings.
FIG. 11 is a flowchart illustrating an example of the operation of the specification generation device 1 according to the present embodiment.
In this figure, first, the control unit 20 of the specification generation apparatus 1 acquires a source file (step S101). That is, the intermediate data generation unit 21 of the control unit 20 acquires the source code described in the source file from the source file storage unit 31 of the file server device 30.

Next, the syntax analysis unit 211 of the intermediate data generation unit 21 performs syntax analysis on the source code acquired from the source file storage unit 31 (step S102).
Next, the symbol execution unit 212 of the intermediate data generation unit 21 generates intermediate data using a symbol execution technique (step S103). That is, the symbol execution unit 212 uses a symbol execution technique based on the analysis result obtained by the syntax analysis unit 211 to analyze the storage variable, the logical expression expressed by the input variable, the value of the storage variable, Intermediate data in which is associated with is generated. The symbol execution unit 212 stores the generated intermediate data in the intermediate data storage unit 11.

  Next, the division processing unit 22 divides the intermediate data based on the input check variable (step S104). That is, the division processing unit 22 uses the intermediate data stored in the intermediate data storage unit 11 as input intermediate data based on the error code storage variable specified by the setting file acquired from the setting file storage unit 32 of the file server device 30. And business intermediate data. The division processing unit 22 causes the divided intermediate data storage unit 12 to store the divided input intermediate data and business intermediate data.

  Further, the business specification generation unit 232 of the simplification processing unit 23 simplifies the business intermediate data based on the logical expression when the input check is successful (step S105). The business specification generation unit 232 acquires the business intermediate data from the intermediate data storage unit 11 and is unnecessary from the business intermediate data based on the logical expression corresponding to the value of the error code storage variable when the input check described above is successful. Simple business intermediate data is generated by deleting simple logical expressions. The business specification generation unit 232 deletes unnecessary logical expressions from the business intermediate data by using, for example, (first method) and (second method). The business specification generation unit 232 stores the generated simplified business intermediate data in the simplified intermediate data storage unit 13.

  Next, the input specification generation unit 231 of the simplification processing unit 23 simplifies the input intermediate data (step S106). The input specification generation unit 231 acquires the input intermediate data from the intermediate data storage unit 11, and uses, for example, the above-described (first method) and (second method) to generate unnecessary logical expressions from the input intermediate data. Is deleted. The input specification generation unit 231 stores the simplified input intermediate data generated by deleting unnecessary logical expressions from the input intermediate data in the simplified intermediate data storage unit 13.

  Next, the design document generating unit 24 formats the simplified input intermediate data and business intermediate data to generate an input check design document and a business process design document (step S107). That is, the input specification shaping unit 241 of the design document generation unit 24 generates an input check design document based on the simplified input intermediate data stored in the simplified intermediate data storage unit 13. Further, the business specification shaping unit 242 generates a business process design document based on the simplified business intermediate data stored in the simplified intermediate data storage unit 13.

  Next, the design document generation unit 24 outputs an input check design document and a business process design document (step S108). That is, the design document generation unit 24 outputs the generated input check design document and business process design document to the file server device 30, and stores the input check design document and business process design document in the design document storage unit 33. After the process of step S108, the design document generator 24 ends the process of the controller 20 of the specification generator 1.

In the example shown in FIG. 11 described above, the processing from step S101 to step S103 corresponds to the intermediate data generation step. Further, the processing in step S104 corresponds to a division processing step. The processing of step S105 and step S106 corresponds to a simplification processing step. Moreover, the process of step S107 and step S108 corresponds to a design document generation step.
Moreover, although the example mentioned above demonstrated an example in case the specification production | generation apparatus 1 produces | generates the input check design document and the business process design document with respect to one source file, the input check design with respect to several source files is demonstrated. Document and business process design document may be generated. In this case, the specification generation apparatus 1 repeatedly executes the above-described processing from step S101 to step S108 according to the number of source files.

Next, an example of input intermediate data simplification processing in the present embodiment will be described with reference to FIG.
FIG. 12 is a diagram illustrating an example of simplification processing of input intermediate data according to the present embodiment. With reference to this figure, the simplification process of the input intermediate data by the above (second method) will be described.

As shown in FIG. 12, in the input intermediate data (SDT5) before the simplification process, the value of the error code storage variable is described in the order of “E1” → “E2” → “E3”. In this case, since the logical expression “XX code ==“ 100 ”” in “E1” corresponds to the logical expression already described, the logical expression LG1 becomes a deletion target (logical expression that does not need to be described). Further, since the logical expression “A-DATE <B-DATE” in “E2” corresponds to the logical expression already described, the logical expression LG2 is a deletion target.
Therefore, the input specification generation unit 231 deletes the logical expressions LG1 and LG2, and generates simplified input intermediate data (SDT6).

  In the above (second method), the logical expression that can be deleted changes depending on the order in which the value of the error code storage variable is written. The input specification generation unit 231 deletes a logical expression that need not be described in a plurality of patterns in which the description order of the value of the error code storage variable is changed, and selects a pattern that can be simplified most among the plurality of patterns. Here, an example of order evaluation by the input specification generation unit 231 will be described with reference to FIG.

FIG. 13 is a diagram illustrating an example of order evaluation in the simplification process of the present embodiment.
In this figure, input intermediate data (SDT1) is input intermediate data before simplification processing, and is an example similar to the input intermediate data shown in FIG. The evaluation result TC1 indicates a buy evaluation result described in the order of “E1” → “E2” → “0” as “order 1”, and the evaluation result TC2 indicates “E2” as “order 2”. The buy evaluation results described in the order of “E1” → “0” are shown.

In the example illustrated in FIG. 13, the evaluation result TC1 based on “order 1” indicates that the number of logical expressions of the input intermediate data (SDT1) is simplified to four, and the evaluation result TC2 based on “order 2” is It shows that the number of logical expressions of the input intermediate data (SDT1) remains six. In this case, the input specification generation unit 231 selects “order 1”.
Note that the input specification generation unit 231 may perform the above-described evaluation for all combinations of orders, for example, using an optimization method that generates a realistic combination such as a genetic algorithm. Also good.

Next, with reference to FIG. 14, an example in which the input specification generation unit 231 executes the simplification process by the (second method) based on the decision tree will be described in detail.
FIG. 14 is a diagram illustrating an example of a simplification process using a decision tree in the present embodiment.
In this example, the “original logical expression” shown in FIG. 14A is simplified based on the “checked condition”. In this case, the input specification generation unit 231 first constructs a “original logical expression” decision tree as shown in FIG. In the decision tree of this figure, the solid line indicates “True” (true) and the broken line indicates “False” (false).

Next, the input specification generation unit 231 assigns the symbol “⊥” (a symbol meaning “anything”) to the “checked condition” portion of the decision tree as illustrated in FIG.
Next, as shown in FIG. 14D, the input specification generation unit 231 deletes a node (a circled portion) that has passed through the decision tree retroactively from the symbol “⊥”. In the example shown here, the node relating to the logical expression “P == 1” remains. As a result, as shown in FIG. 14E, the input specification generation unit 231 generates simplified input intermediate data “E2” if P == 1.
As described above, the input specification generation unit 231 deletes the described logical expression based on the decision tree constructed based on the logical expression.
