Database Integration over Hybrid Networks

The use of intelligent network technology and hybrid networks that include intelligent networks has created new challenges for those who wish to integrate heterogeneous databases distributed across these networks. Advances in public network technology enable the implementation of new distributed database systems that require improved query distribution and optimization algorithms. Reducing response time has typically been the key focus of distributed query execution over traditional networks. The new intelligent and hybrid networks allow optimizations to be made to minimize the communication costs needed to execute queries. In this paper we extend our database integration methodology to hybrid networks by simulating ISDN networks over TCP/IP.
