What is a federated data environment?
In a federated data system, individual source systems maintain control over their own data, but agree to share some or all of this information to other participating systems upon request.

It vastly simplifies querying and analyzing information, and it eliminates the need for users to directly access source systems, which reduces the challenges involved with administering security access to multiple systems.
What is federated in data warehouse?

What is DB2 federation feature?

What is federation system design?

What is Federation in server?
Federation allows single sign-on (SSO) without passwords – the federation server knows the username for a Person in each application and presents that application with a token that says, ” this Person is domain\johndoe or [email protected]”.
