Side-by-side comparison of AI visibility scores, market position, and capabilities
Alation is an enterprise data catalog and analytics governance platform using machine learning to automate data discovery, stewardship, and trusted data access.
About
Alation is an enterprise data catalog and analytics governance platform that uses machine learning to automate the cataloging of data assets — tables, reports, queries, dashboards, and data pipelines — across an organization's data environment, building a searchable inventory of data assets enriched with automatically captured usage metadata that shows which data assets are actually queried, by whom, and how frequently. The platform's behavioral analysis engine monitors query patterns across connected data sources and surfaces data quality signals — such as tables that haven't been queried recently, fields with high null rates, or reports that senior analysts rely on frequently — without requiring data teams to manually assess and document every asset. This automated curation approach allows organizations to build data catalogs that reflect actual data usage rather than idealized documentation that falls out of date as the data environment evolves.
