Re:Isn't this what a *database* is for? (Score 1)

Yes, that's what databases are normally used for. But they can also handle large amounts of data in a efficient way. The aim is to have an unified access to any type of data. This would be fine, but the step from the traditional filesystems to a RDBMS-based system, is too big to work with the old systems. But the proposed RDBMS would internally access the physical data on some HDD and use some internal method to physically store the data. It should provide an interface to support the old filesystem.
