Looker
In plain terms
A business intelligence and data-exploration platform.
Going deeper
Looker lets organizations model data and build dashboards and reports, with a modeling layer (LookML) for consistent metrics. It centralizes analytics definitions.
Under the hood
LookML defines reusable metrics; now part of Google Cloud, querying warehouses directly.
Examples

Think of it like...
Like a shared lens that everyone uses to view the same trusted business numbers.
