Data Governance Best Practices¶

Objective: Master production-grade data governance for distributed analytics systems. When you need to ensure data quality, track lineage, enforce contracts, and maintain reproducibility across Postgres, Parquet, MLflow, and ETL pipelines—these best practices become your foundation.

This collection provides comprehensive guides for metadata management, schema governance, data provenance, and data contracts. Each guide includes architectural patterns, configuration examples, and real-world implementation strategies.

Overview¶

Data governance is the foundation of trustworthy, reproducible analytics. Proper governance enables data quality, lineage tracking, contract enforcement, and schema versioning. These guides cover everything from metadata models to provenance tracking.

Key Topics¶

Metadata & Schema Governance¶

• Metadata Standards, Schema Governance & Data Provenance Contracts - Complete framework for metadata, schema versioning, provenance, and data contracts
• Data Validation and Contract Governance - Comprehensive validation patterns across Postgres, DuckDB, MLflow, Parquet, ETL pipelines, and distributed systems

Data Freshness & Reliability¶

• Data Freshness, SLA/SLO Governance, and Pipeline Reliability Contracts - Comprehensive data freshness governance with SLA/SLO frameworks for ETL pipelines, real-time streaming, geospatial processing, and data serving layers

Data Lifecycle & Retention¶

• Data Retention, Archival Strategy, Lifecycle Governance & Cold Storage Patterns - Comprehensive data retention and archival strategies governing data lifecycle from hot to frozen storage, ensuring compliance, cost optimization, and operational efficiency

Data Quality & Validation¶

• Data Quality SLAs, Validation Layers, and Observability for Tabular, Geospatial, and ML Data - Comprehensive data quality governance with SLAs, multi-layer validation, and observability for tabular, geospatial, and ML data
• Unified metadata model (dataset, column, operational)
• Schema versioning strategies (SemVer, storage patterns)
• Data contracts (API, ETL, geospatial, model)
• Automated validation workflows
• Metadata storage architecture
