Research And Application Of Information Integration Technology Based On XML In E-Commerce

With the development of science and economy, E-commerce has experienced the period of publishing information, and the period in which internet worked as the inter medium of commerce, and then it has been in a new age --"Service-oriented components of e-commerce" . Traditional distributed computing technology CORBA, DCOM and RMI are not fit for the development of electronic business application in Internet which is loose-coupling and heterogeneous network environment with firewall. Many new technical requirements has been brought, such as the remote information exchange, communication between different applications on the heterogeneous platform, a new age of e-business data integration and go through the firewall transparently.These requirements of data integration can be meeted by XML which can be defined by itself and can be expanded. A new model of distributed e-business architecture was presented for Web Services, which is based on XML and aimed at integration and inter-operation between different platforms. While SOA (Service-Oriented Architecture) for e-commerce has provided a new logic structure. Based on these techniques, service-oriented e-commerce system components can be accomplished, and the e-commerce system information which is not only internal but also between internal and external can be integrated conveniently and efficiently.The paper devotes to discuss how to develop an e-business system based on XML Web Services technology. The e-commerce model based on the SOA framework of e-commerce components has been raised and finally applied in Mdebig e-commerce portal. Firstly, data exchange technology based on XML has been researched mostly in this thesis, and the principles has been analyzed, such as the structure of XML documents, the methods of validate the structure of XML, documents, the parsing of XML documents. Secondly, many problems in developing e-business system has been presented, such as frequently updating of commerce flow, the difficulty in information collection, conclusion, integration and transmission of different systems on enterprise platform. Facing these problems, the changes of business operation between enterprises , mode of design and development of business application are needed. Web Service is the best way to solve these problems because it provides effective for the implementation of dynamic e-business. Then the solutions of e-commerce information integration which is based on XML and SOA model are raised, using the Web Service Technology to achieve, with the final realization of the ASP.NET e-commerce system.Many e-commerce services based on the information components have been released in the system, including many components of American companies, such as Google's Map components, yahoo's business information components, the system consists of these components, so the information can be integrated conveniently, and system can be expanded and upgraded with a great convenience. These components can be multiple used separately.
