Abstract: This paper introduces the conception and features of Distributed Heterogeneous DataBase(DHDB), designs distributed heterogeneous database migration system based B/S model, which adopts JDBC SQL data type as the middle one of various data types, implements holistic and partial migration, and introduces type conversion, data migration method, transferred meaning and large data field management, migration process, as well as netants. The feasibility and practicality are proved in project cases.
