Data Quality: understand the concepts and exam cues.
Ensuring data is fit for the purposes for which it is used.
Data Quality (DQ) is the discipline that ensures data is fit for its intended purpose. DAMA frames it not as a one-off technical clean-up but as a continuous, measurable management discipline spanning people, process and technology. It is one of the most operationally tangible chapters in DMBOK2 and maps directly to real-world pain points every enterprise faces.
Inside the companion: this chapter includes an overview, learning objectives, topic priorities, core concepts, exam cues and revision material. Some chapters also include dedicated diagrams and relationship maps.
