What is a database file system?

I have very little information about what a database file system is.

Can someone here explain to me what a database file system is and what its applications are? How is this different from a regular file system?

How can I build it?

Typical file systems (* nix, ms-dos, etc.) arrange files in a hierarchy. For example,

c: \ represents the top of the hierarchy c: \ foo - the next level in the hierarchy c: \ foo \ bar is the sub node of \ foo, etc.

This is a file system in which files have a significant amount of metadata. For example, the iTunes library may be considered the database file system; you not only have files on the disk and know where they are, but you have tags (genres) and other metadata, such as the author (artist).
