A program analysis device includes: a memory that stores an analysis program; and a processor coupled to the memory, the processor preforms operations of: classifying, based on a call relationship between programs in a program asset including the programs and pieces of data, the programs into one or more program groups; generating, based on data which is accessed from the programs included in the program groups, one or more first service component candidates which associates the program groups with the pieces of data; extracting, as common data, data which is updated by another first service component candidate from among the pieces of data associated with the one or more first service component candidate; and setting one or more second service component candidates generated by removing the common data from the one or more first service component candidates and the common data as a service component of the program asset.

Program analysis device for classifying programs into program groups based on call relationship between programs, program analysis method for classifying programs into program groups based on call relationship between programs, and recording medium storing analysis program for classifying programs into program groups based on a call relationship between programs

A method includes: first identifying, from among one or more items included in a source code of a program, a first item used for storing data input to the program or data output by the program; associating, for each of predetermined ranges configuring the source code, an index value, based on a number of the first items referenced in the relevant predetermined range and the number of times the first item is referenced in the relevant predetermined range, with the relevant predetermined range; and outputting an association result of the index value for each of the predetermined ranges.

Method, storage medium, and apparatus

A program conversion program, a program conversion apparatus and a program conversion method that conversions a program having different process according to the content of an argument into a program which facilitate the analysis are provided. The program conversion apparatus includes a dedicated call destination program generating unit that detects the call destination program, an argument for differentiating the processes of the call destination program and the content of the argument from the program group and generates a program for executing only a process according to the content of the argument of the processes of the call destination program as the dedicated call destination program for each argument and each content of the argument, and a call source program rewriting unit that detects the call position for calling the call destination program from the program group and rewrites the call position to call the dedicated call destination program generated by the dedicated call destination program generating unit.
