A federated database system (FDBS) is a type of meta-database management system (DBMS), which transparently maps multiple autonomous database systems into a single federated database. The constituent databases are interconnected via a computer network and may be geographically decentralized. Since the constituent database systems remain ...
Federated architecture as database architecture was first introduced by Denis Heimbigner 1982 [3] and 1985 with the title: A Federated Architecture for Information Management: [4] "This federated database architecture allows a collection of database systems (components) to unite into a loosely coupled federation in order to share and exchange ...

This reduces the risk of data errors, of the workload moving data around that may never be used, and it does not attempt to impose a single data model on the data (an example of heterogeneous data is a federated database system). The technology also supports the writing of transaction data updates back to the source systems. [3]
Data consolidation – The process of capturing master data from multiple sources and integrating it into a single hub (operational data store) for replication to other destination systems. Data federation – The process of providing a single virtual view of master data from one or more sources to one or more destination systems.
The most widely known example is the Internet, which is Federated around the Internet Protocol (IP) stack of protocols. Another, more visible, example is Email , where the common use of the Simple Mail Transfer Protocol (SMTP), allows alice@gmail.com to communicate with bob@example.edu and eve@hotmail.com although the software implementing each ...
