PROBLEM TO BE SOLVED: To provide a system design support device of an SOA architecture for generating a macro-service as a coarse virtual service by combining a business process and a service in fine granularity in designing an SOA system.;SOLUTION: This system design support device of an SOA architecture for constructing a business process, and for assigning a service to the components is provided with a main storage device 105 in which a processing means is stored and a central processing unit 101 for executing a processing means stored in the main storage device 105. The central processing unit 101 executes the processing means, and generates a macro-service as a virtual service whose detail level of the system components is coarse from the subset of the business process to which the service has been already assigned in the detail level of the fine system components.;COPYRIGHT: (C)2009,JPO&INPIT
