That's a fair question. I think the main issue is the level of abstraction: databases are more abstract than filesystems, and depend on properly working filesystems for their correct operation. A database is one particular application of data storage, while a filesystem is a general mechanism for data storage.

Data bases depend on filesystems for their correct operation?

What about native Pick, where the database IS the filesystem?

Or Oracle, where it's configured to use raw partitions for data storage?

Cheers,

I'd argue that those databases implement their own filesystems.
