With the contrast between classic Web technologies and Web 2.0 technologies, we represent a sample of enterprise information system based on Web 2.0, and show how the use of Web 2. 0 technologies changes the system data exchange model of the enterprise information systems and how it improves the efficiency and effectiveness of information systems.展开更多

The presentation layer plays the key role, converging the external information from the collaboration layer to the inside of information system （IS）, and diffusing the internal information from the service layer to public users. This framework can also illustrate how users contribute to producing new services, and how web services are integrated to collaborate with public users.展开更多
