Research on IETM Heterogeneous Data Integration of Quartermaster Equipment Based on XML

How to integrate heterogeneous data is the key problem of IETM. The paper designs the IETM integration framework structure based on XML technology, and then discusses three primary problems: data description, data storage and data parsing. After these research works, heterogeneous data is retrieved more quickly, maintain cost of equipment is reduced, efficiency of equipment is enhanced and the security of information is assured. And at the same time, the most important things are data integration and sharing problems have been effectively solved.
