The key to realize the organized integration of various data sources is how to specify all kinds of data by a unique data schema and mask the heterogeneity of their platforms and data structure, etc. there are some shortage in existing data integration systems : complex conversion of any data schema to the common schema ; little integration about semistructured data ; lackness of interoperability in bottom level communication mechanism based on software component
