Abstract: In order to resolve the problem of integrating the dispersed and heterogeneous original data and generating accurate and consistent objective data efficiently, a service-oriented data Exchange platform is built based on SOA and Web service technologies. The platform makes full use of the newest XML-binary Optimized Packaging(XOP) criterion and packages data as the attachment of XOP message. Several design strategies such as data encoding rules, transmission mode, security of the platform and data consistency are specially discussed. Practical enterprise application indicates that the platform can deal with 400 thousands recodes with images daily and achieves the continuous transmission of large quantities of data and operations stably with high efficiency.
