| Abstract(in English) | We propose a new metric that measures the reusability in case of migrating from legacy system to service-oriented system (SOA), and a method to measure the metric. First of all, we compare two services in functional aspects; the first one, we call this necessary service, is a service which is obtained by analyzing business process using top-down approach. The second one, we call this candidate service, is a service which is obtained by analyzing source codes using bottom-up approach. Then, we analyze how exiting candidate services are reusable to realize necessary services. Finally, we measure the ratio of the reusable legacy system based on size metrics. As a result of applying proposal technique to existing liquor management system, we could confirm that we are able to measure potential reusability ratio of the service in the existing system quantitatively. |
