The DAMA Data Modelling and Design exam spans 4 domains, and they are not weighted equally. The top areas are Data Modeling Fundamentals, Database Design, Advanced Modeling and Design. Budget your study hours to match those weights; the full domain list is in the outline section further up this page.

The DMD-1220 exam is DAMA's official certification test, and passing it earns the CDMP credential at the Specialist (CDMP Practitioner / Master Track) level. In career terms, it is verified proof of skill — the kind that moves you up the shortlist when your company works with DAMA technologies, or when you apply to one that does. The same track also includes Certified Data Management Professional (CDMP), Data Management Fundamentals (DMF-1220), so this exam can anchor a longer certification plan.

You pass the DAMA Data Modelling and Design exam at 70% (Practitioner), 80% (Master), and each attempt costs USD $311 — fail, and that fee is due again in full for the retake. Treat mock exams as insurance: keep practicing with Prep4away until your scores sit comfortably above 70% (Practitioner), 80% (Master) twice in a row, then schedule the real DMD-1220 exam.

Please do. Prep4away offers a free demo download for the DAMA Data Modelling and Design exam — grab it from the product page or leave your email and we will send it over. Purchases come with 365 days of free updates; after that year, extending the update service costs 50% of the original price in your member zone.

The DAMA Data Modelling and Design exam packs 100 questions into 90 minutes. That ratio leaves almost no room for stalling, so time management is a trained skill, not luck. Our suggestion: rehearse full-length timed sessions in the Prep4away engine, learn to park a question and return later, and walk into the DMD-1220 exam with a pacing plan already rehearsed.

For CDMP Practitioner level, candidates must pass Data Management Fundamentals (DMF-1220) and two Specialist exams with a minimum score of 70%. Since DAMA revises these rules from time to time, confirm the current prerequisites on the official exam page (https://dama.org/certification/exam-information-and-pricing/) before booking your DAMA Data Modelling and Design exam.
