Application Study Of Service-Oriented Architecture And Web Services

While IT executives have been facing the challenge of cutting costs and maximizing the utilization of existing technology, at the same time they have to continuously strive to serve customers better, be more competitive, and be more responsive to business's strategic priorities. The IT industry has faced two problem of isomer and change and they has been struggling to find solutions to solve above problems. Nnow we have find Web Service base on Service-oriented architecture as a good solution.For Present ,the international company and organizations such as IBM, Microsoft, OASIS, w3C have done much work on the Service-oriented architecture and Web Service. Then a series of basic protocols and criteria have established for their works.With a service-oriented architecture, we can realize several benefits to help organizations succeed in the dynamic business landscape of today as follow: Leverage existing assets; Easier to integrate and manage complexity; More responsive and faster time-to-market; Reduce cost and increase reuse;At first the thesis outlines the service oriented architecture concept and acadamic knowledge. Then we discuss the characteristic of Web service and correlative basic specifications and protocols, focus on the web service security. And then we describe the EleCommerce electronic business system from its analysis design to implement; in which we apply UML visualization model technology to build analysis and design model. By development EleCommerce system, We practiced dot NET platform technology, validated the feasibility of developping Web Service technology, enjoyed invoking Web services of heterogeneous system from remote server. The next we studyed the accessing Web services ability limited of velocity from the ASPX page and created asynchronous ideal solution. At the last, we give some conclusion and foresight.
