Abstract
Disclosed is a federated architecture and system which are extensible and flexible for integrated access to heterogeneous DataBase Management Systems (DBMS) dispersed over a long haul network, allowing transparent access to a wide variety of DBMS while maintaining the local autonomy of the underlying DBMS. In addition the system can run on top of different hardware, operating systems, network communications, and DBMS. The system can include new target DBMS with minimum changes and is not limited to integrate relational DBMS, but also to integrate legacy DBMS such as hierarchial or network DBMS, spatial information or text retrieval systems.
