Abstract
In order to protect the existing investment and achieve effective integration of heterogeneous data sources data at lower cost,the paper expands the traditional mediator integrated model,which is composed by four modules including semantic processing,integrated algorithm processing,optimization and implementation of the engine.In addition,to meet the characteristics of heterogeneous data integration,the article defines the data structure of heterogeneous data integration,and certifies correctness of the model by using Web services composition technology.
