Research Of Service-Oriented Modeling Method And Its Application In Finance Auditing System

In order to resolve problems such as tight-coupling, redundancy and so on, Service-Oriented Architecture (SOA) and related technologies are brought in to address these problems and to improve Finance Auditing System.Firstly, we discuss the background and urgent problems existed in Finance Auditing System. Secondly, the concept, characters and related technologies are introduced, and the important concept "service" is explained in detail. Then, UML modeling method is borrowed to form the new service modeling method which can be used in analysis and design of software systems. After being reconstructed using the service modeling method, the Finance Auditing System will become more flexible and extensible. Lastly, the key services of Finance Auditing System are implemented using Web Services technologies, and be tested by application using C# programming language, which means problems of communications between heterogeneous systems are resolved.The new service modeling method is neutral which implied that the method is platform and OS (Operation System) independence and can be applied to any software systems.
