Following the fast development of Internet and rapid change in information technology, many companies have lots of information systems. However,the phenomenon of many SMEs's(small and medium-sized enterprises) lack of information systems is becoming more and more obvious. They also face numerous system integration problems. So majority of SMEs urgently want to accelerate the construction of information system so as to increase productivity and enhance competitiveness. With the emergence of SOA (service-oriented architecture), Web service-oriented EAI (enterprise application integration) platform has become one of the main development directions of SMEs's information system. And it also brings new opportunities and challenges to the ISV and ASP operators.This thesis studied the EAI development status and trends at home and abroad, pointed out the shortcomings and deficiencies of current mainstream of EAI model which was illustrated afore. Combined with Web-based ASP service application model, the feasibility of using it in the field of EAI was discussed, and the key techniques of ASP-based service platform for EAI were deeply analyzed.Based on above research, Combined with the existing EAI technology trends and the current market situation, Web service-oriented EAI business mode was constructed according to the needs of the majority of SME customers. And the basis of implementing this model– Web service-oriented EAI platform– was presented. This thesis analyzed the platform design and functional structure with detail, and especially the realization of some important module was introduced.After the overall planning and design completed, according to the current situation for SMEs, this thesis studied the smart client technology, and illustrated how to achieve the application services development and integration in the platform with an example of CAE service.Finally, the prospect of further development in this field was given, and the change from web service to semantic web service was introduced. To promote the understanding and reasoning in Web services of manufacturing industry, ontology-based modeling method was used so as to carry out the dynamic combination.
