The Application On XML Data Exchange Technology In Online Mall

The development of the online mall system requires co-processing of themultiple department business system. These data in different development platformsand databases at different periods may give rise to the heterogeneous data which havesome difficulties in co-processing and sharing.The data exchange technologydeveloped quickly,but the XML has an obvious advantage that can realize the dataexchange of different structures and formats among various systems. Therefore,it is ofcertain significance to research the application of the XML data exchange technologyto the online mall.This paper summarizes the present research situation of the XML data exchangetechnology at home and abroad, and discusses the generation and development of theXML technology. It also analyzes some defects of the existing online mall system ondata exchange among the heterogeneous system. It designs an online mall system usedXML data exchange technology on the basis of these defects.In addition,it presents the XML data exchange model,and accomplish datatransmission by the usage of SOAP protocol, and uses three layers of B/S model andthe J2EE technology to achieve data exchange. Finally the paper shows that the “dirtydata” generated by the data exchange of various heterogeneous data systems may becleaned by using the data cleaning technology which completes the cleaning via Webdata elements, Web data standardization and Web data mapping so as to improve thequality of data information.The designed online mall based on XML data exchange includes three parts, thatis, the foreground function, the background management and the data processingcenter. The foreground is mainly related to the operations of online mall suppliers andretailers about shopping and submitted orders of the users.The backgroundmanagement is mainly related to the managers who complete the management oforders, commodity information and the crew.The data processing center includes datatransmission and data exchange which mainly complete data exchange betweenheterogeneous systems.
