Research of Integrated Model of Mining Information Heterogeneous Database

Combining with the advantages of XML and Web Service,the paper proposed an integrated model of mining information heterogeneous database,and expounded technical implementation of the model. The practice proved that in the case of unchanging storage and management mode of original data,the model could realize unified and transparent visit for heterogeneous data source well and ensure integrity, security and consistency of the data,which has high efficiency in development.
