Definition: A data management body of knowledge published by DAMA International that provides 11 Knowledge Areas and practical guidelines for organizations to effectively manage data assets — a global standard framework.

Characteristics: (The DAMA Wheel) Presents a DAMA Wheel structure in which data governance is the central hub, organically connected to 10 management areas. (A business-asset perspective) Supports a shift in perspective that treats data not as an IT asset but as an enterprise-wide business asset. (A maturity benchmark) Provides a benchmark for diagnosing data management maturity and building an organizational capability improvement roadmap.

Area	Core Purpose	Key Activities
1. Data Governance	Establish enterprise-wide data management policy, strategy, and accountability	Define data ownership, set policy, ensure compliance
2. Data Architecture	Standard design of enterprise data structure and flow	ERD, conceptual/logical/physical model design
3. Modeling & Design	Formalized representation of data requirements	Normalization, model review, metadata registration
4. Storage & Operations	Data storage infrastructure and operational management	DB administration, backup, recovery, performance tuning
5. Data Security	Data access control and privacy protection	Access rights management, encryption, PII masking
6. Integration & Interoperability	Data linkage across heterogeneous systems	ETL, API, data hub design
7. Documents & Content	Systematic management of unstructured data and documents	Content classification, retention policy, search optimization
8. Reference & Master Data	Ensuring consistency of core shared data	MDM implementation, golden record management
9. Data Warehousing & BI	Integrating data for analytics and delivering insight	DW design, OLAP, dashboards, reporting
10. Metadata	Managing information about data’s meaning, origin, and context	Data catalog, data lineage tracking
11. Data Quality	Ensuring the accuracy, completeness, and consistency of data	Quality measurement, profiling, cleansing/standardization

B. The Data Management Framework (DAMA Wheel)

Design Principle	Description
Governance-centered	Data Governance sits as the hub of the wheel, directing and setting policy for the other 10 areas
Interconnected areas	The areas are not independent — metadata, quality, and security cut across all of them
Enterprise-wide application	An integrated framework that systematizes data management capability across the whole organization, not a single department

3. Expected Benefits and Practical Application of DAMA-DMBOK
