A Service-Oriented Analysis and Design Approach Based On Data Flow Diagram

In the paper, we analyze the shortages of service-oriented analysis and design (SOAD) methodologies, and then review the features of data flow diagram as a kind of requirement analysis technology. Finally, we propose an SOAD method using DFD diagram. Therefore, a process is provided as a guideline to aid analyst to accomplish high-quality service identification with the method. Through an illustration of the SOAD, we can conclude that the method has several strong points compared to methodologies else based on business process and enterprise architecture.
