| Abstract(in English) | To facilitate adaptation of legacy software for the service-oriented architecture (SOA), this paper presents a method that systematically extracts services from source codes of a procedural system. We first obtain data flow diagrams (DFDs) from the given source codes with the existing reverse-engineering technique. Then, we define dependencies among processes on the DFDs by classifying the data into three categories. Based on the dependencies, we propose six rules that aggregate several processes on the DFDs as a self-contained service. We have conducted an experiment for an existing legacy application (liquor management system). As a result, it was shown that services with various granularities were identified reasonably from the source codes. |
