Key best practices include: implementing duplicate detection algorithms during extraction, creating strong validation rules, running regular audits and data profiling, and establishing continuous monitoring with governance frameworks. Common issues like duplicate records, inconsistent formats, and missing values can affect 10-30% of business records. Organizations with robust data management practices see 15-20% gains in operational efficiency. The post also highlights that 43% of organizations cite data accuracy as the main barrier to AI success, and references Decube's platform features (automated monitoring, lineage tracking, ML-powered anomaly detection) as tools to support these practices. ## Full article daily.dev links to this article rather than hosting it.
