- Tables (Managed, Exterior, and International): structured information like transactions, occasions, or buyer profiles.
- Views: filtered or aggregated slices of your tables.
- Volumes: information corresponding to photos, audio, paperwork, or personal code libraries.
- Notebooks: SQL or Python notebooks that outline the evaluation you need to run.

Clear Rooms add a safe, managed house for multi-party evaluation when information should keep personal. Companions can be part of information belongings, run mutually accepted code, and return solely the outputs that each one sides agree on.

- Solely notebooks that you simply and your companions approve can run on serverless compute in an remoted atmosphere.
- Notebooks write to momentary output tables, so that you management precisely what leaves the clear room.

In a Databricks Clear Room, you possibly can have as much as 10 organizations (you plus 9 companions) working collectively in a single safe atmosphere, even should you’re on totally different clouds or information platforms. Every crew retains its information in its personal Unity Catalog and solely shares the precise tables, views, or information they need to use within the clear room.
