Alation
Alation is a data catalog and governance platform that helps data analysts discover, understand, and trust enterprise data. It crawls databases, BI tools, and data lakes to auto-generate metadata and usage stats. A built-in search engine surfaces relevant tables, columns, or dashboards. Analysts can tag, comment, or rate datasets, building tribal knowledge. Alation also includes data lineage visuals and policy management for compliance. By combining machine learning with collaborative curation, Alation fosters a culture of data self-service while maintaining governance. Ideal for mid to large companies wanting a strong data discovery layer.
