# HR Integrations: Source Systems and Data Feeds

> Reference the source systems that feed the Human Resources domain, what each provides, and how Spine Fabric ingests and uses that data.

The HR domain draws from multiple source systems to keep people data current. Spine Fabric ingests each through connectors, normalizes events, and links entities so practitioners see one unified record.
