In one of the companies, we used it as an information tool. We created a logical model so that the business would know what was in the offices down to the warehouse. The current use case is also the same. We have some places for information, so we can do a logical data model for them, but, usually, it would go towards building an actual database, which also involves reverse engineering of an existing one because people don't know what's in there.
It is currently on-prem, but we still have a separate server.
