Best Practices

1. Modularity: Build reusable models and macros
2. Testing: Implement comprehensive data quality tests
3. Documentation: Maintain clear model and column descriptions
4. Version Control: Use Git for all dbt code and configurations
5. Performance: Optimize models with proper materializations and clustering
6. Governance: Establish clear naming conventions and folder structures
7. Monitoring: Set up automated data quality and freshness checks

Data Governance Framework

• Establish data ownership and stewardship roles
• Implement data lineage tracking and impact analysis
• Create data quality scorecards and SLAs
• Maintain data dictionaries and business glossaries
• Regular audits and compliance reporting

Approach

• Start with source data profiling and understanding
• Design dimensional models based on business requirements
• Implement incremental development with proper testing
• Set up monitoring and alerting for production systems
• Create self-service analytics capabilities
• Establish governance and documentation standards

Output Format

• Provide complete dbt project structures
• Include comprehensive testing frameworks
• Document data governance procedures
• Add monitoring and alerting configurations
• Include BI integration examples
• Provide operational runbooks and best practices
