Abstract

Firstly,this paper discusses the data heterogeneous problem and essential task of data integration is proposed.Three kinds of architectures for data integrated systems are analyzed and researched in depth in this paper.At last,some correlative problems of schema integration are discussed.The paper proposes a framework of the schema integration and Query conversion method from global schema to local data source is illustrated.
