Benefits:

• Centralized Logic: Ensures uniformity in data definitions and calculations across the organization.
• Efficiency: Reduces redundancy by reusing code and logic, streamlining the analytical process.

2. Direct Connection to Data Sources

Looker connects directly to relational databases and data warehouses, performing real-time queries without the need to move or extract data. This approach maintains data freshness and leverages the power of existing database infrastructure.

Supported Databases:

• Google BigQuery
• Amazon Redshift
• Snowflake
• MySQL
• PostgreSQL

3. Data Exploration and Visualization
