Great mterest has been paid in data mining by researchers in different fields. In this paper,data mining techniques are introduced broadly including its definition,purpose,characteristic, principal processes and classifications. As an example,the studies on the mining association rules are illustrated. At last,some data mining prototypes are provided and several research trends on the data mining are discussed.展开更多

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
