Connecting DBeaver, or any tooling similar to that (SSMS) to OneStream’s internal database isn’t really an option since OneStream is a SaaS platform. Direct database access would likely violate the terms of service, and credentials aren’t provided for security reasons.
For working with application data, OneStream’s Data Integration tools or reporting features is the best way to view the application data if needed. If you share more about what you’re trying to achieve, the community can suggest some solid alternatives within OneStream
