In recent years, demand for electronic transactions and problems of early electronic trading architecture derived the securities intermediate system. Although the securities intermediate system has resolved most of the needs and problems of electronic transactions, the system is still constrained by traditional design pattern of tight coupling. The objective of this study is to improve accounting functions of securities intermediate system with Service-Oriented Architecture (SOA). We use the method of service-oriented modeling and architecture (SOMA) to analyze the accounting functions and identify the required candidate services. We then establish a new SOA layered architecture with service orchestration and composition. The SOA solution of this study not only retains the original functions of the securities intermediate system but also promote the agility to increase overall responsiveness to future business or technology change. The developed prototype also can serve as a reference for adjusting or building similar securities systems.
