1️⃣ What is a Data Quality Analyst?

A Data Quality Analyst is a professional responsible for ensuring that data used by an organization is accurate, consistent, complete, and reliable. They analyze datasets, identify errors, remove duplicates, correct inconsistencies, and establish standards to maintain high-quality data.

In simple terms:
