TAILIEUCHUNG - Federated Database Systems for Managing Distributed, Heterogeneous, and Autonomous Databases’

This inception report provide therefore the opportunity to propose a clearer view of the activities of the ESPON DB project than the answer to the tender where the template was not adapted to the specificities of our activities. If we admit that networking & coordination or diffusion are core part of our project and not peripheral activities, we can define our work plan for the next 30 months as a set of 4 main field of activities divided in 14 Work packages, as presented in Figure logical and hierarchical presentation of the project has been précised in a PPT. | Federated Database Systems for Managing Distributed Heterogeneous and Autonomous Databases1 AMIT p.

Hillsboro Oregon 97124 A federated database system FDBS is a collection of cooperating database systems that are autonomous and possibly heterogeneous. In this paper we define a reference architecture for distributed database management systems from system and schema viewpoints and show how various FDBS architectures can be developed. We then define a methodology for developing one of the popular architectures of an FDBS. Finally we discuss critical issues related to developing and operating an FDBS.
