System characterization system and system characterization device

摘要

To evaluate the priority of an section of a system to be improved.SOLUTION: A software structure analysis unit 1011 analyzes a relationship between a calling relationship among programs in source code and data, and generates a graph structure with nodes representing programs and directional edges representing the calling relationship among programs. A characteristic analysis unit 1021 calculates a characteristic value of a business system 30 for each node on the basis of an analysis result of the source code and operation information or fault information of the business system 30, in which and the program are executed. An improvement section analysis unit 1023 merges node on the basis of the characteristic value and reconstructs the graph structure on the basis of a result of the node merging.SELECTED DRAWING: Figure 2
