Looker Enterprise BI Platform

Looker is an enterprise business intelligence and data analytics platform acquired by Google in 2020 and now integrated into Google Cloud as part of the Agentic Data Cloud. It differentiates itself from traditional BI tools through its governed semantic layer built using LookML, a declarative modeling language that defines metrics, dimensions, relationships, and business logic in version-controlled code files rather than in opaque proprietary metadata stores. This approach ensures consistent metric definitions across the entire organization, eliminating the conflicting numbers problem that plagues spreadsheet-driven analytics. The platform features conversational analytics powered by Gemini AI, allowing users to ask natural language questions and receive governed, trustworthy answers grounded in the semantic model rather than hallucinated responses. Data scientists and business analysts can define complex derived metrics, persistent derived tables, and parameterized queries directly in LookML, which are then exposed to business users through interactive dashboards, self-service exploration interfaces, and scheduled data delivery. The Looker API enables developers to embed analytics into external applications, automate report generation, and build custom data applications using the embedded analytics framework. The platform supports connections to dozens of database systems including BigQuery, Snowflake, Redshift, PostgreSQL, and SQLite through SQL-based dialect adapters. Version control integration with Git repositories enables collaborative model development with code review and CI workflows. Governed data experiences combine row-level security, content access permissions, and parameterized embedded dashboards for multi-tenant SaaS analytics scenarios.
