Design and Implementation of the National RD Information System Based-on Service-Oriented Architecture

摘要

In this paper, we have designed and implemented the National R&D Information system(RnDIS) based on SOA for the integrated search of national R&D information. The function of heterogeneous applications each linked to a different DB are connected and integrated for the effective use of the information through the concept of SOA. The CBD method is expanded to define a new method for system implementation through identification, definition and analysis of the service and four different application services and business process services have been designed and implemented for the RnDIS. The application service adopted wrapping method that creates a WSDL from the Java code and the business service uses the BPEL engine to orchestrate the application services. The RnDIS is serviced through the main page of the NTISas a search function in the menu and will continuously expand the data for service and its function for the service.
