Data Federation

Data federation is an integration approach that lets you query data where it lives, across multiple systems, without physically copying it into a central store.

A federation layer translates a single query into calls against each source, such as a CRM and a data warehouse, and returns a combined result.

This contrasts with ETL, which extracts, transforms, and stores data elsewhere.

A practical example

Example: a revenue team wants pipeline value from the CRM joined with web engagement data in the warehouse.

Instead of adding a nightly sync, they use a federation layer so reports query both systems live at run time.

What to evaluate before investing

  • Ask which sources the federation layer supports natively and whether your specific CRM version is included.
  • Check how queries perform at scale, since live federation depends on source systems responding quickly.
  • Confirm how access control works: does the federation layer enforce source-level permissions or bypass them?

Limitations and tradeoffs

Federation shifts load onto source systems at query time; heavy reporting against a production CRM can degrade its performance for the sales team using it.
