Semantic Web Services-based Enterprise Heterogeneous Systems Application Integration And Realization

Following with the improvement of social informationization, there are more communications and interactions needed among enterprise information systems. They should share data and cooperate with each other to complete business affairs. But for the historical and other reasons, enterprise information systems are mostly heterogeneous. So it is an essential problem to provide an efficient integration mechanism to realize application integration of heterogeneous systems, avoid enterprise "information islands" and optimize enterprise business processes.Researches on Enterprise Application Integration (EAI) technologies have attracted much focus from both academic and industrial fields. There are some approaches introduced to deal with some certain problems of enterprise integration. Especially Web Service technology provides a very good idea and basis for integration of heterogeneous systems. But, in the whole, these traditional approaches mostly adopt distributed component and message broking as their main supporting technologies. They mainly focus their attention and emphasize the communication, interaction and data sharing between application systems. However, following the development of global informationization and changing of business operation mode driven by network technologies, there are some new challenges to EAI offered by industries. These new challenges are mostly focused on management of business processes in integration. The main goal of this dissertation is to research and discuss models and methods of business-oriented and semantic-based application integration under these new challenges.EAI means two things: one is sharing of enterprise information and resources and the other is integration of enterprise business processes. It demands more semantic level integration besides basic communication of enterprise information systems. Enterprise business processes need to be flexibly configured, dynamically generated and cooperatively executed. Changing of enterprise operation model brings some new demands for integration of information systems, which include:...
