Abstract: In order to create a massive infrastructure composed of highly diverse interconnected mobile entities, form a united data management environment, a data management approach for large-scale mobile terminal called MTDM is presented and described in this paper. The registration, querying and data delivery of the mobile object entity are discussed. MTDM is a good and efficient system which is strongly supported by the cache and data directory technology. Results obtained from example analysis show that MTDM can implement the data sharing, storing and querying for mobile entities.
