  As described above, according to the present invention, when a program created by a user does not match the software architecture, a function related to a function that does not match can be specified. This makes it easy to make modifications that conform to the architecture.

  FIG. 1 is a schematic diagram of an information providing apparatus 100 according to the first embodiment of the present invention.

  As illustrated, the information providing apparatus 100 includes a storage unit 110, a control unit 120, an input unit 130, and an output unit 140.

  The storage unit 110 has a model storage area 111 and a program storage area 112.

  The model storage area 111 stores information for specifying the relationship between modules that can be referred to in the software architecture.

  For example, in the present embodiment, a model table 111a as shown in FIG. 2 (schematic diagram of the model table 111a) is stored.

  The model table 111a stores information for identifying a reference source module and a reference destination module that are permitted to be referenced as a relationship between modules that are permitted to be referenced in the software architecture.

  Specifically, the model table 111a is provided with a reference source module name column 111b and a reference destination module name column 111c. In the reference source module name column 111b and the reference destination module name column 111c on the same line, In the software architecture, the module names of reference sources and reference destination modules that are allowed to be referenced are stored.

  The reference source module name column 111b stores information for uniquely specifying a reference source module that is allowed to be referenced in the software architecture. Here, in the present embodiment, the module name is used as information for uniquely identifying a reference source module that is allowed to be referenced in the software architecture. However, the present invention is not limited to such an aspect. It is also possible to use an assigned ID or the like.

  In the reference destination module name column 111c, information that uniquely specifies a reference destination module that is specified by the module name stored in the reference source module name column 111b in the same row and is allowed to be referenced in the software architecture. Is stored. Here, in the present embodiment, the module name is used as information for uniquely identifying a reference destination module that is allowed to be referenced in the software architecture. However, the present invention is not limited to this mode. For example, each module is uniquely identified. It is also possible to use an assigned ID or the like.

  In this embodiment, as shown in FIG. 2, it is assumed that the reference from the module A to the module B and the reference from the module B to the module C are permitted in the software architecture. That is, a reference relationship between other modules, for example, a reference from module A to module C, a reference from module B to module A, a reference from module C to module B, and a reference from module C to module A Is a software architecture reference violation.

  The program storage area 112 stores information for specifying a module and information for specifying a program belonging to the module.

  For example, in this embodiment, as shown in FIG. 3 (schematic diagram of the program table 113 and the file 114), the program table 113 and the file 114 are stored.

  In the program table 113, information for specifying a program belonging to each module is stored for each module.

  For example, the program table 113 in the present embodiment includes a module name column 113a and a file name column 113b.

  The module name column 113a stores information for uniquely specifying a module in each program table 113.

  For example, in the present embodiment, a module name is stored as information for uniquely specifying a module.

  The file name column 113b stores information for uniquely specifying a program belonging to the module specified by the module name stored in the module name column 113a.

  For example, in the present embodiment, the file name of the program file is stored as information for uniquely specifying the program.

  In the program storage area 112, a file 114 storing a program is stored in association with the file name column 113b.

  The control unit 120 includes a reference relationship analysis unit 121, a reference relationship inspection unit 122, and a related function analysis unit 123.

  The reference relationship analysis unit 121 specifies a reference relationship by specifying a function call destination module and function in a program belonging to a specific module stored in the program storage area 112.

  For example, in the present embodiment, the reference relationship analysis unit 121 acquires the module name and the file name of the program belonging to the module from the program table 113 for each module, and the program of the file 114 corresponding to the acquired file name To identify the functions included in the program.

  Then, the function called by the identified function is extracted, the file 114 of the program having the extracted function is identified, and the file name is identified.

  Further, the module name to which the function extracted from the module name column 113a of the program table 113 storing the specified file name is specified.

  Then, the reference relationship analysis unit 121 identifies the reference relationship by associating the module name and function of the reference source with the module name and function of the reference destination. In this way, the reference relationship is specified for the functions included in all programs stored in the program storage area 112, and the specified reference relationship is stored in the storage unit 110 as reference relationship information.

  The reference relationship checking unit 122 checks each reference relationship included in the reference relationship information specified by the reference relationship analyzing unit 121 to determine whether or not reference is permitted in the software architecture.

  For example, in the present embodiment, the reference relationship inspecting unit 122 identifies and specifies the module name that is the reference source and the module name that is the reference destination from each reference relationship specified in the reference relationship analysis unit 121. Whether or not there is a row in which the module name stored in the column corresponding to each of the reference source module name column 111b and the reference destination module name column 111c of the model table 111a stored in the model storage area 111 is present To do.

  When there is such a line, the reference relationship checking unit 122 is allowed to refer to the software architecture, and when there is no such line, the reference is not permitted in the software architecture. (It is a reference violation).

  The related function analysis unit 123 analyzes a method for eliminating the reference relationship that is determined to be a reference violation by the reference relationship checking unit 122. Here, in the present embodiment, the related function analysis unit 123 generates detour candidate function information that detours the function call in order to eliminate the reference relationship determined to be a reference violation.

  Specifically, in the present embodiment, the related function analysis unit 123 converts the function of another module that is calling the reference destination function in the reference relationship determined as a reference violation by the reference relationship checking unit 122 to the reference relationship. Extracted from the reference relationship information identified by the analysis unit 121.

  Next, the related function analysis unit 123 sets the module name of the module to which the extracted function belongs as the reference source module name, and the module name of the reference destination module in the reference relationship determined to be a reference violation as the reference destination module name. Is stored in the model table 111 a of the model storage area 111.

  If there is such a line, the module name of the reference source module in the reference relationship determined to be a reference violation is set as the reference source module name, and the module name of the module to which the extracted function belongs is referred to as the reference destination module name. It is determined whether or not the line to be stored is in the model table 111a of the model storage area 111. If there is such a line, information associating the extracted function with the module name to which the function belongs is obtained as bypass candidate function information. To do.

  Next, the related function analysis unit 123 extracts another function calling the function acquired as the detour candidate function information from the reference relationship information identified by the reference relationship analysis unit 121.

  Then, the related function analysis unit 123 uses the module name of the module to which the extracted function belongs as the reference source module name, and the line with the module name of the module to which the function obtained as the detour candidate function information belongs as the reference destination module name. It is determined whether or not it exists in the model table 111a of the storage area 111. If there is such a line, the module name of the module of the reference source in the reference relationship determined to be a reference violation is the reference source module name, and the module name of the module to which the extracted function belongs is the reference destination module name. Is stored in the model table 111a of the model storage area 111, and when there is such a line, information associating the extracted function with the module name to which the function belongs is obtained as bypass candidate function information.

  By repeatedly performing the above processing until new detour candidate function information is not acquired, the related function analysis unit 123 directly or directly selects the reference destination function in the reference relationship determined to be a reference violation by the reference relationship checking unit 122. The function of another module that is indirectly called (and the name of the module to which the number of buildings belongs) is acquired as bypass candidate function information.

  FIG. 4 is a schematic diagram for explaining a process for generating detour candidate function information performed by the related function analysis unit 123.

  In FIG. 4, modules are indicated by nodes surrounded by rectangles, and functions belonging to each module are indicated by nodes surrounded by rounded rectangles. And the directed edge shown with the continuous line which connects between the nodes which show a module shows the relationship between the modules in which reference is permitted in software architecture. That is, the reference between the modules in the direction of the directed edge is permitted in the software architecture (note that the reference relationship within one module is allowed). In addition, the directed edge indicated by the broken line connecting the nodes indicating the function indicates the calling relationship of each function. That is, the function of the direction indicated by the directed edge is called. Further, the characters in the node indicating the function indicate (module name, function).

  Here, the directed edge of the node 161 of the function f1 belonging to the module A extends to the node 162 of the function h2 belonging to the module C, and this reference relationship becomes a reference violation.

  Therefore, the related function analysis unit 123 includes a node 163 indicating a function of another module in which the directed edge extends to the node 162 of the function h2 belonging to the module C, and the directed edge extends to the node 163. The node 164 is searched, and it is confirmed that there is no reference violation even if the directed edge is extended from the node 161 to these nodes 163 and 164, and the module name and function specified by these nodes 163 and 164 are bypassed. It is specified as function information.

  Further, the related function analysis unit 123 processes the detour candidate function information acquired as described above into a predetermined display format, and displays it on the output unit 140 described later.

  As a predetermined display format, for example, as shown in FIG. 5 (schematic diagram showing a display example of detour candidate function information), a reference source module name and function are shown to indicate a reference relationship that has resulted in a reference violation. An arrow (→) is placed from the module name and function of the reference destination ("module C, h2" in FIG. 5) from (module A, f1 in FIG. 5) to the bottom of the reference relationship that resulted in a reference violation. Detour candidate functions ("module B, g3" and "module B, g2" in FIG. 5) are listed.

  Further, the predetermined display format is not limited to such an aspect. For example, as shown in FIG. 6 (schematic diagram showing a display example of the detour candidate function information), the reference relation that has become a reference violation is displayed. Candidate functions can be displayed in ascending order of the number of nodes leading to the reference function. In FIG. 6, the number located to the left of the candidate function indicates the number of nodes up to the reference destination function of the reference relationship in which the reference violation occurred.

  Furthermore, as a predetermined display format, for example, as shown in FIG. 7 (schematic diagram showing a display example of detour candidate function information), nodes up to the reference destination function of the reference relationship that has become a reference violation are displayed. It is also possible to display the route.

  The information providing apparatus 100 configured as described above can be realized by a so-called computer 170 as shown in FIG. 8 (schematic diagram of the computer 170).

  For example, the storage unit 110 can be realized by an external storage device 171 such as a hard disk, and the control unit 120 reads a predetermined program stored in the external storage device 171 into the memory 172 and a CPU (Central Processing Unit) 173. The input unit 130 can be realized by an input device 174 such as a keyboard or a mouse, and the output unit 140 can be realized by an output device 175 such as a display.

  Below, the flow of the process in the information provision apparatus 100 is demonstrated using PAD (Problem Analysis Diagram).

  The PAD is described in detail in [Yoshihiko Fumimura, “Program Technique-Structured Programming by PAD (Information Engineering Fundamental Course 4)”, Ohmsha, 1984].

  FIG. 9 is a PAD showing processing for inputting a program to the information providing apparatus 100.

  First, when inputting a program to the information providing apparatus 100, the operator of the information providing apparatus 100 inputs the program, the file name for storing the program, and the module name to which the program belongs through the input unit 130. Accept (S10).

  Next, the control unit 120 of the information providing apparatus 100 searches the program storage area 112 for the input module name, and stores the program in association with the input module name entry (S12).

  Specifically, a new entry is created in the file name column 113b of the program table 112a included in the module name column 113a having the input module name, and the input file name is stored in the created entry. The stored program is stored in the program storage area 112 as a file having the input file name.

  FIG. 10 is a PAD showing processing by the reference relationship analysis unit 121 of the control unit 120.

  First, in step S20, the reference relationship analysis unit 121 stores all the programs stored in the program storage area 112 in the variable P, and repeats the processes in steps S21 to S25.

  Next, in step S21, the reference relationship analysis unit 121 stores the module name to which the program P belongs in the variable M1.

  The module name of the program P may be acquired from the module name column 112b of the program table 112a that has been searched by searching the file name column 112c of the program table 112a for the file name of the program.

  In step S22, the reference relationship analysis unit 121 stores all the functions in the program P in the variable F, and repeats the processing in steps S23 to S25 for each function.

  Next, in step S23, the reference relationship analysis unit 121 stores all the functions called by the function F in the variable G, and repeats the processing in steps S24 and S25 for each function.

  In step S24, the reference relationship analysis unit 121 stores the module name to which the program having the function G belongs in the variable M2.

  As for the module name to which the program having the function G belongs, the program having the function G is specified from the file 114 stored in the program storage area 112, and the file name of the specified file 114 is specified in the file name column 112c of the program table 112a. From the module name column 112b of the hit program table 112a.

  In step S25, a reference relationship in which an element (M1, F) that associates the module M1 with the function F is a reference source element, and an element (M2, G) that associates the module M2 with the function G is a reference destination element. Is acquired as reference relationship information.

  FIG. 11 is a PAD showing processing by the reference relationship checking unit 122 of the control unit 120.

  First, in step S30, the reference relationship inspecting unit 122 uses all the reference relationships having the elements (M1, F) acquired by the reference relationship analyzing unit 121 as reference source elements and the elements (M2, G) as reference destination elements. Each of them is stored in a variable K, and the processing in steps S31 to S33 is repeated for each reference relationship.

  Next, in step S31, the reference relationship inspecting unit 122 stores the module M1 of the reference source element in the reference source module name column 111b and the module M2 of the reference destination element stored in the reference destination module name column 111c. It is confirmed whether there is a row in the model table 111 a stored in the model accumulation area 111.

  If there is such a line, the process proceeds to step S32, and no processing is performed. If there is no such line, the process proceeds to step S33, and the element (M1, F) is set as a reference source element. The reference relationship K having the element (M2, G) as a reference destination element is specified as a reference violation.

  FIG. 12 is a PAD showing a process of generating detour candidate function information by the related function analysis unit 123 of the control unit 120.

  First, in step S <b> 40, the related function analysis unit 123 extracts an arbitrary reference relationship among the reference relationships identified as a reference violation by the reference relationship checking unit 122, and stores it in the variable J.

  Here, the reference relationship J may be extracted by any method. For example, the reference relationship identified by the reference relationship checking unit 122 as being violated by reference is displayed as a list on the output unit 140, and the input unit 130 includes the reference relationship. The operator of the information providing apparatus 100 may make a selection via

  In step S41, the related function analysis unit 123 stores the elements (M2, G), which are reference destination elements of the reference relationship J, in the variable CAND as the initial value of the variable CAND.

  Next, in step S42, the related function analysis unit 123 repeats the processes in steps S43 to S46 until the number of elements of the variable CAND does not increase.

  In step S43, the related function analysis unit 123 stores the module name and the function in each of the variables M3 and G3 for all elements of the variable CAND, and repeats the processing in steps S44 to S46 for each element.

  In step S44, the related function analysis unit 123 stores the module M3 in the reference source module name column 111b in the row in which the module M3 is stored in the reference destination module name column 111c in the model table 111a stored in the model accumulation area 111. Is stored in the variable M4.

  In step S45, the related function analysis unit 123 identifies all functions that call the function G3 in the program stored in the file 114 stored in the program storage area 112 corresponding to the module M4, and identifies the identified function. A set (H1,...) Hj) is generated.

  In step S46, the related function analysis unit 123 adds elements {(M4, H1),..., (M4, Hj)} in which the module name is associated with the function specified in step S45 to the variable CAND.

  In step S47, the related function analysis unit 123 stores the module name and the function in the variable M5 and the variable G5 for all elements included in the variable CAND, respectively, and the module M1 of the reference source element is the reference source module name. The element stored in the column 111b and the module M5 of the reference destination element is stored in the reference storage module name column 111c and the element existing in the model table 111a stored in the model storage area 111 is extracted and extracted. This set of elements is stored in the variable CAND2.

  In step S48, the related function analysis unit 123 acquires information for specifying an element included in the variable CAND2 as bypass candidate function information.

  The detour candidate function information acquired in this way is displayed in a predetermined display format via the output unit 140.

  FIG. 13 is a schematic diagram of an information providing apparatus 200 according to the second embodiment of the present invention.

  Since the present embodiment differs from the first embodiment in the processing in the related function analysis unit 223, items related to this different point will be described below.

  The related function analysis unit 223 in the present embodiment performs processing for generating transfer candidate function information in addition to the processing in the related function analysis unit 123 in the first embodiment.

  FIG. 14 is a schematic diagram for explaining transfer candidate function information generation processing performed by the related function analysis unit 223.

  In FIG. 14, as in FIG. 4, modules are indicated by nodes surrounded by rectangles, and functions belonging to each module are indicated by nodes surrounded by rounded rectangles. And the directed edge shown with the continuous line which connects between the nodes which show a module shows the relationship between the modules in which reference is permitted in software architecture. That is, the reference between the modules in the direction of the directed edge is permitted in the software architecture (note that the reference relationship within one module is allowed). In addition, the directed edge indicated by the broken line connecting the nodes indicating the function indicates the calling relationship of each function. That is, the function of the direction indicated by the directed edge is called. Further, the characters in the node indicating the function indicate (module name, function).

  Here, in FIG. 14, the node 261 of the function h2 belonging to the module C has a directed edge extending to the node 262 of the function g2 belonging to the module B, and this reference relationship is a reference violation.

  In this regard, even if the related function analysis unit 223 performs the same process as the process in the first embodiment, the node 263 and the node 264 calling the node 262 directly or indirectly cannot be called from the node 261 ( Because it becomes a reference violation, it is not possible to present a node that can eventually be bypassed.

  In such a case, in accordance with an instruction from the operator of the information providing apparatus 200 via the input unit 130, the related function analysis unit 223 selects a function that is a reference violation as either a reference source or a reference destination module. It is determined whether or not the reference violation is resolved.

  For example, the related function analysis unit 223 extracts, from the reference relationship information identified by the reference relationship analysis unit 121, other functions called by the reference destination function in the reference relationship determined to be reference violation by the reference relationship checking unit 122. In addition, by repeating the process of extracting other functions called by the extracted function, the reference destination function in the reference relationship determined to be a reference violation and the reference destination function called directly or indirectly Specify the function.

  Then, the related function analysis unit 223 uses the reference destination function in the reference relationship determined to be a reference violation and other functions that are directly or indirectly called by the reference destination function in the reference relationship determined to be the reference violation. It is determined whether or not the reference violation is resolved by moving to the module to which the reference source function belongs.

  This determination refers to the module name of the module to which the function that calls the reference function in the reference relationship determined to be a reference violation or another function that is directly or indirectly called by the reference function. The determination is made based on whether or not there is a line in the model table 111a of the model storage area 111 that uses the original module name and the module name of the reference source in the reference relationship determined to be a reference violation. When there is such a row in the model table 111a, the reference destination function in the reference relationship determined to be a reference violation, the other function that is directly or indirectly called by the reference destination function, and these Information specifying the module name to which the function belongs is acquired as transfer candidate function information.

  In addition, the related function analysis unit 223 extracts other functions that call the function of the reference source in the reference relationship determined to be a reference violation by the reference relationship checking unit 122 from the reference relationship information specified by the reference relationship analysis unit 121. In addition, by repeating the process of extracting other functions that call the extracted function, the function of the reference source in the reference relationship determined to be a reference violation and the function of the reference source are directly or indirectly called. Specify the function.

  Then, the related function analysis unit 223 uses the reference function in the reference relation determined to be a reference violation and the other function that directly or indirectly calls the reference source function in the reference relation determined to be the reference violation. It is determined whether or not the reference violation is resolved by moving to the module to which the reference destination function belongs.

  This determination refers to the module name of the module to which the function that calls the reference source function in the reference relationship determined to be a reference violation and another function that directly or indirectly calls the reference source function belongs. The determination is made based on whether or not there is a line in the model table 111a of the model storage area 111 that uses the original module name and the module name of the reference source in the reference relationship determined to be a reference violation. When there is such a row in the model table 111a, the reference source function in the reference relationship determined to be a reference violation, the other function that directly or indirectly calls the reference source function, and these Information specifying the module name to which the function belongs is acquired as transfer candidate function information.

  Then, the related function analysis unit 223 processes the transfer candidate function information acquired as described above into a predetermined display format and displays it on the output unit 140 described later.

  FIG. 15 is a PAD showing a transfer candidate function information generation process by the related function analysis unit 223 of the control unit 120.

  First, in step S <b> 50, the related function analysis unit 223 extracts an arbitrary reference relationship from among the reference relationships identified as a reference violation by the reference relationship checking unit 122, and stores it in the variable I.

  Here, the reference relationship I may be extracted by any method. For example, the reference relationship identified by the reference relationship inspecting unit 122 as being in violation of the reference is displayed in a list on the output unit 140, and the input unit 130 is displayed. The operator of the information providing apparatus 100 may make a selection via

  Next, in step S51, the related function analysis unit 223 causes the function g2 in the element (B, g2) that is the reference destination element of the reference relationship I and all the functions that the function g2 calls in the module B directly or indirectly. Is transferred to the module C to determine whether or not the reference violation is resolved. If the reference violation is resolved, the function g2 and all the functions g2 in the module B that are directly or indirectly called Information specifying the function is acquired as transfer candidate function information.

  Whether or not the reference violation is resolved is determined by using the module name of the function g2 and the function g2 that calls the function g2 in the module B directly or indirectly as the reference source module name. The determination may be made based on whether or not there is a line having B as a reference module name in the model table 111a of the model storage area 111.

  The transfer candidate function information can also include information for specifying the module C that is the transfer destination.

  Next, the related function analysis unit 223 is a module that includes the function h2 in the element (C, h2) that is the reference source element of the reference relationship I and all the functions that directly or indirectly call the function h2 in the module C. It is determined whether or not the reference violation is resolved by moving to B. If the reference violation is resolved, the function h2 and all the functions that directly or indirectly call the function h2 in the module C are Information to be specified is acquired as transfer candidate function information.

  Note that whether or not the reference violation is resolved is determined by using the module name of the function h2 and all functions that directly or indirectly call the function h2 in the module C as the reference source module name. The determination may be made based on whether or not a line having C as a reference module name exists in the model table 111a of the model storage area 111.

  The transfer candidate function information can also include information for specifying the module B that is the transfer destination.

  The transfer candidate function information acquired in this way is displayed in a predetermined display format via the output unit 140.

  FIG. 16 is a schematic diagram of an information providing apparatus 300 according to the third embodiment of the present invention.

  Since the present embodiment differs from the second embodiment in the processing in the related function analysis unit 323, items related to the different points will be described below.

  The related function analysis unit 323 in the present embodiment performs processing for generating correction candidate function information in addition to the processing in the related function analysis unit 223 in the second embodiment.

  FIG. 17 is a schematic diagram for explaining correction candidate function information generation processing performed by the related function analysis unit 323.

  In FIG. 17, as in FIG. 4, modules are indicated by nodes surrounded by rectangles, and functions belonging to each module are indicated by nodes surrounded by rounded rectangles. And the directed edge shown with the continuous line which connects between the nodes which show a module shows the relationship between the modules in which reference is permitted in software architecture. That is, the reference between the modules in the direction of the directed edge is permitted in the software architecture (note that the reference relationship within one module is allowed). In addition, the directed edge indicated by the broken line connecting the nodes indicating the function indicates the calling relationship of each function. That is, the function of the direction indicated by the directed edge is called. Further, the characters in the node indicating the function indicate (module name, function).

  Here, in FIG. 17, the directed edge of the node 361 of the function h2 belonging to the module C extends to the node 362 of the function g2 belonging to the module B, and this reference relationship is a reference violation.

  In this regard, even if the node 362 is transferred to the module C by the same processing as the processing in the second embodiment by the related function analysis unit 323, there is a call from the node 362 to the node 363. End up.

  In such a case, in accordance with an instruction from the operator of the information providing apparatus 300 via the input unit 130, the related function analysis unit 323 presents correction candidate function information for correcting a function that is in violation of the reference. To do.

For example, the related function analysis unit 323 is a correction proposal that corrects the configuration of the program as shown in the following (1) to (4).
(1) A variable for holding the function is provided in the module of the reference source in the reference relationship determined as a reference violation by the reference relationship inspecting unit 122.
(2) A new function that receives the function and sets the received function in the variable provided in (1) is provided in the module of the reference source in the reference relationship determined to be a reference violation by the reference relationship checking unit 122.
(3) The reference source function in the reference relationship determined to be a reference violation by the reference relationship checking unit 122 is changed to call the variable provided in (1).
(4) It is determined that the reference function for the reference source module in the reference relationship determined as a reference violation by the reference relationship checking unit 122 is a reference violation for the new function provided in (2). A new function is provided for performing the process of setting the reference function in the reference relationship to the variable provided in (1).

  For modules that are allowed to be referenced with respect to the reference source module in the reference relationship determined to be a reference violation, the reference module name in the model table 111a stored in the model storage area 111 is referred to as a reference violation. Any one of the module names of the reference source modules in the determined reference relationship may be selected according to a predetermined rule.

  For such correction candidate function information, for example, when there is a reference violation as shown in FIG. 17, FIG. 18 (schematic diagram for explaining generation processing of correction candidate function information performed by the related function analysis unit 323) ), A variable 364 for holding the function in the module C and a new function h3 for receiving the function and setting the received function in the variable 364 are provided (node 365). Then, in module C, the function h2 (node 361) of the reference source in the reference relationship determined to be a reference violation is changed so as to be called from the variable 364, and the module B has a new function h3 provided in the module C. For (node 365), a new function g3 (node 366) that causes the variable 364 to be set to the function g2 (node 362) of the reference destination in the reference relationship determined to be a reference violation is provided. .

  FIG. 19 is a PAD showing processing for generating correction candidate function information by the related function analysis unit 323 of the control unit 120.

  First, in step S <b> 50, the related function analysis unit 323 extracts an arbitrary reference relationship among the reference relationships identified as a reference violation by the reference relationship checking unit 122 and stores the extracted reference relationship in the variable L.

  Here, the reference relationship L may be extracted by any method. For example, the reference relationship identified by the reference relationship inspecting unit 122 as being in violation of the reference is displayed as a list in the output unit 140, and the input unit 130 includes the reference relationship. The operator of the information providing apparatus 100 may make a selection via

Next, in step S61, the related function analysis unit 323 generates correction candidate function information including the following (1) to (4).
(1) A variable hhh for holding a function is provided in the module C in the element (C, h2) which is a reference source element of the reference relationship L.
(2) A function h3 that receives a function in the module C in the element (C, h2) that is a reference source element of the reference relationship L and sets the received function in a variable hhh is provided.
(3) The function h2 in the element (C, h2) that is the reference source element of the reference relationship L is changed to the module C instead of the function g2 of the module B in the element (B, g2) that is the reference destination element of the reference relationship L. Rewrite to call the provided variable hhh.
(4) A function g3 for setting the function g2 of the module B to the variable hhh is provided in the module B in the element (B, g2) which is the reference destination element of the reference relationship L by using the function h3 of the module C.

  In the above processing, it is assumed that reference from module B to module C is permitted. However, when such reference is not permitted, function g3 provided in (4) is given to module C. It is also possible to provide it in other modules that are allowed to refer to.

  The function provided in (4) is executed at least before executing the function rewritten in (3).

  The correction candidate function information generated in this way is displayed in a predetermined display format via the output unit 140.

  FIG. 20 is a schematic diagram showing an example of a program modified along the modification candidate function information presented in step S61 in FIG. 19 when the program is in C language.

  For example, the variable provided in (1) in step S61 of FIG. 19 is described by reference numeral 381, the function provided in (2) is described by reference numeral 382, and the function rewritten in (3) is expressed by reference numeral 383. The function provided in (4) is described in reference numeral 384.

  In the embodiment described above, the model storage area 111 stores information for specifying the relationship between modules that are allowed to be referenced in the software architecture. However, the present invention is not limited to this mode. In this case, information for specifying the relationship between modules that are not allowed to be referenced may be stored.
