Report from Presenter

IEEE International Conference on Software Analysis, Evolution, and Reengineering (SANER) 2017 was held in Klagenfurt, Austria from February 21st through 24th, 2017. SANER is the premier research conference on the theory and practice of analyzing and improving existing software. It presents research findings on innovative ways including tools to support source code analysis and understanding. Researchers and practitioners held 89 presentations and enthusiastic discussions on the latest research in this field at SANER 2017.

Hitachi Group presented "Business Process Recovery Based on System Log and Information of Organizational Structure" providing research findings on methods on how to recover abstract business processes by using existing legacy system logs. Legacy systems are now often used in a way deviated from the expected operation when the system was designed, and therefore if we refer to the old system design document while maintaining or migrating it to a new system, a problem may occur. Our proposed method allows you to visualize actual business processes by using system logs and organizational structure information and drawing a business process flow diagram on the way how the legacy system is operated (Fig. 1). If we draw a process flow diagram from normal system logs as they are, too much detailed process flow by operation is drawn. However, by grouping multiple operations with operator and operator's organizational information, it gets possible to draw an adequate granular abstracted business flow diagram for viewing the whole of business processes (Fig. 2).

We help our customers efficiently migrate their system by applying this technique to System Modernization updating legacy systems to up-to-date IT infrastructure.
