Abstract: This document describes the points in design and implement of OBS. The system process flow, architecture and data gather interface are designed based on analysis of business model. The Web applications are implemented with JSF, entity Bean, JPA and annotation, meanwhile the external interface communicates with other systems through Web Service and the content format of messages and data file is XML. OBS architecture is clear and tasy to be extended with the new characteristics of Java EE 5.
