A professional-level summary covering key definitions, frameworks, and exam-relevant points.
Definition and Scope
According to the DAMA DMBOK v2, Data Governance is defined as "the exercise of authority, control, and shared decision-making (planning, monitoring, and enforcement) over the management of data assets." It is the highest-level function in the DMBOK framework, providing direction and oversight to all other data management knowledge areas.
Data governance encompasses the policies, processes, standards, roles, metrics, and oversight mechanisms that ensure data is managed as a valuable enterprise asset. It is distinct from data management in that governance sets the rules, while management executes them.
Core Components
The DMBOK identifies the following core components of a data governance programme: governance organisation (council, working groups, data owners, stewards), data governance strategy (vision, goals, principles), data governance policies and standards, data governance processes (issue management, change management, escalation), data governance tools and metrics, and a governance operating model (federated, centralised, or hybrid).
Key Roles
The Chief Data Officer (CDO) or equivalent executive sponsor provides strategic leadership. The Data Governance Council is the cross-functional decision-making body. Data Domain Owners hold accountability for specific subject areas (e.g., Customer, Product, Finance). Data Stewards are subject-matter experts responsible for day-to-day data quality and compliance within their domain.
Governance vs Management
A critical CDMP distinction: governance is about authority and decision-making, while management is about execution and operations. The governance function decides what the rules are; the management functions (data quality, metadata, security, etc.) implement those rules. The CDMP exam regularly tests this distinction.
CDMP Exam Weight
Data Governance carries an 11% weighting in the CDMP exam — one of the highest-weighted domains. Candidates should expect 10–12 questions directly testing governance concepts, roles, operating models, and the relationship between governance and other DMBOK knowledge areas.
