An integration framework for information system based on web service

In recent years, there has been a growing interest to implement the integration of information systems running on different environments. And most of information systems are being designed based on client/server, peer to peer; and recently agent architectures. These systems have major drawbacks because of their limitations in scalability, availability, distribution of computing power and storage system, as well as sharing information between users that contribute in these systems. This paper will use the web service technology as scalable, flexible, coordinated and secure resource sharing among distributed individuals and institutions, and the different information systems. Meanwhile, by implementing the encapsulation of information system based on multi-agent technology and the integration of these web services, we are able to reuse the functionalities of different information systems. In this way, many service providers and content providers can contribute in developing a very large scale integrated information system platform.
