This paper analyzes the data exchange modes among different systems,proposes a XML-based data exchange middleware model, which focuses on solving the problems in data exchanging a-mong heterogeneous EC systems. The key technologies in data exchange middleware model are studied, which includeexchange service interface, ontology, data exchange engine and template. Lastly, the XSLT is extended according tothe data exchange requirements.展开更多

Researchers proposed several strategies or algorithms, which improve the performance and scalability of the Webcluster system. In this paper, a content-based load distribution algorithm is proposed. It takes the processing ability ofback-end severs and the request load weight into account, and ensure the request locality. The emulation results illus-trate that this algorithm performs better in different kinds of Web site, comparing with other relative algorithms.展开更多

But the heterogeneous of the information systems between companies makes it difficult in interoperating between them. In this paper, a B2B electronic business collaboration model is proposed, solving the collaboration between heterogeneous business systems by defining the business irformation ontology and describing the hierarchy in business collaboration process.展开更多
