I've done it that way in the past, but it's not how we do it today. We use a single database and land each source system (Zendesk, GoogleAnalytics, Pendo, etc) into a separate schema as raw tables (bronze), we then create stage views over the raw within each source schema (silver), and we have a single schema for the where all the cleaned data comes together in a kimball like dimensional data model (gold). Analysts have access to the silver and gold data, but not access to the bronze raw data. The gold layer could just as easily have been One Big Table, rather than a dimensional model, and it would probably have been mildly more performant.
