The Cloudera Navigator metadata component provides data discovery and data lineage management functions. The architecture of the Cloudera Navigator metadata component is illustrated below.
The Navigator Metadata Server performs the following functions:

- Extracts entity metadata from the services at periodic intervals
- Manages and applies metadata extraction policies
- Indexes and stores entity metadata
- Manages user authorization data
- Manages audit report metadata
- Implements the Navigator UI and REST API
The Navigator Metadata database stores entity metadata, policies, and user authorization and audit report metadata.
