Abstract :
Existing federated database systems (FDBS) provide uniform access to multiple heterogeneous DBS, but do not enable objects to move across the DBS while retaining global identity. To fulfil this requirement of industrial users, we provide a framework incorporating a flexible object migration mechanism into FDBS. It offers different capabilities for “what” and “how” to migrate: (1) different kinds of objects that exist within an FDBS, (2) various migration degrees that determine what data to migrate of an object, and (3) different operation primitives to move, replicate, and copy objects
