data governance

The overarching framework of policies, roles, and technical controls ensuring data availability, integrity, and security.

Detailed Explanation

Data governance is the operational and technical strategy to prevent a company's data ecosystem from becoming a toxic swamp. It establishes who owns the data, who can access it, how long it is retained, and how its quality is measured.

With the rise of GenAI, governance has expanded to restrict what data embeddings and LLMs can consume to prevent confidential information leakage.

Why It Matters

It is the only defense against regulatory fines, data breaches, and AI systems exposing executive salaries to interns.

Common Failure Mode

A company dumps all its data into a data lake without governance. Two years later, nobody knows what data is accurate, reports conflict, and compliance audits fail miserably.

Practical Example

Applying a governance rule using BigQuery column-level security to restrict PII access.

Production Manifestation

Data catalogs (e.g., Collibra, Amundsen), IAM policies, PII masking rules, and automated compliance auditing pipelines.
