A data catalog is a centralized metadata repository that helps organizations discover, understand, and manage their data assets. Key features include automated metadata crawling, data lineage tracking, access controls, and collaboration tools. Modern catalogs like Decube leverage AI for automated quality evaluations and anomaly detection. Organizations using data catalogs report 30-50% reductions in data search time and up to 50% less quality rework.
