Study and technological realization about heterogeneous data integration based on XML Schema

The data Integration method based XML Schema is put forward in this paper, by the combination of model method based XML and schema mapping method, schema integration is realized, thus, public schema is produced, lastly, the mapping rules between public schema and local schema are created. The process of this method, such as schema conversion, conflict resolution and schema Integration, is particularly presented. In the end, the application of this method is demonstrated by means of examples. The method has been proved to be feasible by experimental results.
