Research and optimization of data Consolidation method based on XML Schema

XML is a self- describing and platform- free language, which has become a powerful tool when exchanging and sharing information among different heterogeneous system on internet. The data Consolidation method based XML Schema is put forward in this paper, by the combination of model method based XML and schema mapping method, schema Consolidation 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 Consolidation, 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.
