Governed, Self-Service Data Access

Why wait weeks to create the dashboards you need in order to derive value from your data?

Dremio’s semantic layer empowers data analysts and data scientists to discover, curate, analyze, and share datasets in a self-service manner.

Consistent View of Data for All Users and Tools

Why define isolated definitions of data, calculated fields, and virtual datasets in individual BI tools where they can’t be used by your teammates?

You can use Dremio’s semantic layer to create dataset definitions, calculated fields, and security rules that can be leveraged by any downstream application.
