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 fulfill 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. 1 Introduction In many enterprises, multiple different database systems have been built or acquired over the last several years. When data communication became easier, the request for coupling databases increased to allow controlled sharing of data. The approach of federated database systems (FDBS) [8, 16] became very important in this field because it retains the autonomy of the multiple existing het...
