Abstract
System analysis programs have been developed by several different research groups. Especially, the programming languages and the developing environments of algorithm modules and user interface modules are different. And therefore, the differences have degraded interoperability and reusability of the system analysis modules. in order to solve this problems, a general binary interface has designed and the component based on the interface has developed as well. However, sometimes each interface is uncompatible because those are designed on the particular vendor. In this paper, we deals with XML web service, Sort of distributed processing architecture, which is not restricted by not only the existing internet standard but also any Programming language or any vendor. Because of its platform independent, each module can be updated and extended independently.
