If you've read anything about data quality in a professional context, you've probably encountered references to DAMA — often alongside phrases like "DAMA DMBOK" or "the six data quality dimensions." DAMA is the closest thing the data management profession has to a universally recognized authority.
Here's what it is, why it matters, and what it actually says about data quality.
What Is DAMA?
DAMA International (Data Management Association International) is a nonprofit professional organization for data management professionals, founded in 1988. Its primary contribution to the field is the DMBOK — the Data Management Body of Knowledge — which is the definitive reference guide for data management practices.
The DMBOK (currently in its second edition, DMBOK2, published in 2017) is a comprehensive framework covering all aspects of enterprise data management: data governance, data architecture, data modeling, data quality, master data management, metadata management, data security, business intelligence, and more.
DAMA is not a software vendor, not a certification body (though it supports certifications like the CDMP — Certified Data Management Professional), and not a consulting firm. It's a standards and knowledge organization — its influence comes from the quality and adoption of the DMBOK.

The DAMA Data Quality Framework
DAMA's contribution to data quality is primarily its framework of six core data quality dimensions, which has become the most widely used standardized definition of data quality in professional practice.
The six dimensions:
1. Completeness — The degree to which all required data is present. Are mandatory fields populated? Are all expected records present?
Sohovi profiles every column in your dataset for completeness and flags the exact rows where values are missing — free to try.
2. Validity — The degree to which data conforms to defined formats, data types, and business rules. Is the date in an acceptable format? Is the status one of the allowed values?
3. Accuracy — The degree to which data correctly represents the real-world entity or event it describes. Is the address actually correct? Is the amount the real transaction value?
4. Consistency — The degree to which the same data is represented identically across systems and over time. Does "New York" mean the same thing in the CRM and the analytics tool?
Sohovi finds gaps, duplicates, and format errors in your CRM data — so your team is working from records they can trust.
5. Timeliness — The degree to which data is available and current for its intended use. Is the pricing data current? Is the contact information recently verified?
6. Uniqueness — The degree to which each entity is represented only once. Are there duplicate customer records, duplicate transactions, duplicate products?
DAMA's 6 vs. Other Dimension Frameworks
DAMA's six dimensions are not the only framework. ISO/IEC 25012 defines 15 quality characteristics. Some enterprise tools use 10+ dimensions. The DAMA framework is notable for its pragmatism: six dimensions are enough to cover the most common and most costly data quality failures, without creating a framework so complex that it's impractical to use.
For most businesses — and for most data quality tooling — the DAMA six dimensions are the practical standard.
DAMA's Data Management Wheel
DAMA also contributed the "Data Management Wheel," a visual framework showing the 11 knowledge areas of data management (data governance, data architecture, data modeling, data quality, etc.) with data governance at the center — the organizing principle around which all other practices revolve.
This wheel is widely used in data management education and certification programs. Its practical value: it reminds practitioners that data quality is one component of a larger discipline, and that quality without governance (who owns it, who enforces it) is insufficient.
The CDMP Certification
DAMA offers the CDMP (Certified Data Management Professional) certification, which is the most recognized credential in data management. The certification exam covers all 11 knowledge areas of the DMBOK. For data professionals, a CDMP signals comprehensive knowledge of data management practices — not just technical skills.
Why DAMA Matters If You're Not a Data Professional
Even if you're a small business owner or an ops manager rather than a data architect, DAMA's framework is useful for two practical reasons:
1. Common language. When you talk to a data vendor, consultant, or hire a data analyst, DAMA's framework is the language they're likely using. Knowing that "completeness" means something specific (not just "is the data good?") helps you ask better questions.
2. A proven set of dimensions to measure. You don't need to invent your own data quality framework. DAMA's six dimensions cover the most important failure modes in practice. Use them as your checklist.
The Bottom Line
DAMA and the DMBOK are the closest thing to an industry-wide standard in data management. The six data quality dimensions DAMA defined are used in tools, certifications, vendor documentation, and enterprise quality frameworks worldwide. Understanding what DAMA is — and what its framework says about data quality — gives you a shared language with the broader data profession and a proven starting point for your own quality practice.
