Abstract


With the rapid development of Web services and related technologies , the enterprise business integration gradual transition to a service-oriented architecture on top . Web services based on service-oriented architecture integrated distribution , autonomy , as there is an urgent need to address the problem . Dynamic integration of the basic features of the Web services integration , Web services integrated core is to coordinate a number of Web services work together through Web services integration , flexible, enterprise business logic model . Existing Web services integration model and the implementation program did not expect to achieve the enterprise maturity, has not yet been widely used . The systematic study of the Web service , Web services integrated operation quality system for the lack of existing Web services integration program , effectively evaluate and optimize the means proposed QoS and probability -driven Web services integration strategy . The policy to the Web service QoS model and probability model, calculated in Web services , Web services , quality of service, as a reference standard for Web services selection process . Proposed dynamic programming to solve the multi strategy to achieve dynamic integration of Web services , and the loose network environment , real view maintenance solutions proposed conceptual transaction model , give a real view of the consistency maintenance algorithm , a better solution based on schema materialized view consistency maintenance issues. The proposed Web services integration framework to process-oriented Web services -based integration technology , demand analysis, process definition , a Web service to retrieve and Web service returns data integration , and finally form a global data chain , enterprise business logic .
