🛡️ Data Governance

Data Governance

A framework of policies, processes, and standards for managing data assets across an organization, ensuring data is secure, compliant, and properly used.

Data governance is the framework that defines who can take what actions, on what data, under what circumstances, using what methods. It establishes accountability, policies, and procedures for managing enterprise data assets.

Core Components of Data Governance

1. Data Ownership: Assigning accountability for data assets to specific individuals or teams
2. Data Stewardship: Day-to-day management and quality oversight
3. Data Policies: Rules governing data usage, retention, and access
4. Data Standards: Naming conventions, formats, and definitions
5. Data Catalog: Inventory of data assets with metadata

Key Governance Domains

- Data Quality: Ensuring data meets defined standards
- Data Security: Protecting sensitive information
- Data Privacy: Compliance with regulations (GDPR, CCPA)
- Master Data Management: Maintaining single source of truth
- Metadata Management: Documenting data lineage and definitions

Frequently Asked Questions

What is data governance in simple terms?

Data governance is a set of rules and processes that define who can access what data, how data should be managed, and who is responsible for data quality and security. Think of it as the "government" for your data.

Why is data governance important?

Data governance ensures data is accurate, secure, and compliant with regulations. Without it, organizations face risks like data breaches, compliance fines, poor decisions from bad data, and inefficient operations.

What is the difference between data governance and data management?

Data governance defines the "what" and "why" (policies, standards, ownership). Data management is the "how" (actual implementation of storage, processing, and delivery of data). Governance is strategic; management is operational.

What is a data steward?

A data steward is responsible for the day-to-day management and quality of specific data domains. They ensure data meets quality standards, maintain documentation, and act as a point of contact for data-related questions.
