According to the present invention, an analysis unit configured to analyze weights of a plurality of structural elements included in the structural information and weights of dependency relationships of each of the plurality of structural elements based on the structural information and a plurality of execution histories, a structural element designation unit configured to designate one of the structural element among the structural elements included in the structural information as a designated structure element, a display information calculation unit configured to calculate display information including a dependency structural element being a structural element having a dependency relationship with the designated structure element and a weight of the dependency structural element, and a correspondence between the designated structural element and the dependency structural element and a weight of the correspondence, and a display configured to display the display information.

Software analysis apparatus

Even when one refactoring operation cannot establish a target software structure, an appropriate refactoring operation establishes the target software structure. An improvement proposing device includes: a structure comparator to output, as an improvement object, a difference between a first software structure and a second software structure different in software structure from the first software structure; and an improvement plan examining unit to examine an improvement plan for each improvement portion in the improvement object, the improvement plan being a method for bringing the first software structure closer to the second software structure.

Proposing device and improvement proposing method

A software analysis device being capable of analyzing dependency between software components more comprehensively and with higher accuracy than a conventional technology is provided. The software analysis device comprising: a first analyzing unit that statically analyzes a structure of a source code of software and analyzes dependency between objects of the software; and a second analyzing unit that executes a program indicated by the source code to acquire first information regarding an operation of the objects and analyzes dependency between the objects based on the first information. The software analysis device analyzes dependency between the objects based on an analysis result of the first analyzing unit and an analysis result of the second analyzing unit.

Software analysis device, software analysis method, and software analysis program

A source code analysis unit identifies dependency strengths of one or more functions included in a source code. An influence analysis unit identifies one or more transfer functions that will each move to a different subsystem due to refactoring and identifies a dependency strength to be influenced by the refactoring, based on the dependency strengths that have been identified by the source code analysis unit with respect to the one or more transfer functions. A scale calculation unit calculates the scale of the refactoring, based on the dependency strength to be influenced, which has been identified by the influence analysis unit.

Scale calculation apparatus and computer readable medium

A direct relationship extraction unit generates a direct relationship list indicating a set of a direct dependence source, a direct dependence destination, and a direct dependence type. A storage unit stores an indirect relationship rule including a plurality of direct dependence types, an element relationship, a dependence source element, and a dependence destination element. An indirect relationship extraction unit extracts, from a direct relationship list, a plurality of pieces of direct relationship information corresponding to the plurality of direct dependence types and the element relationship included in the indirect relationship rule, extracts an indirect dependence source which is an element corresponding to a dependence source element in the indirect relationship rule from the extracted plurality of pieces of direct relationship information, and extracts an indirect dependence destination corresponding to a dependence destination element in the indirect relationship rule from the extracted plurality of pieces of direct relationship information.
