"Database File System; It is a new type of file system that does away with places where you store your files. Actually do not think of it as a file system, instead think of it as a document system. And while being precise, it is not database system either, it is a faceted system?. It is a file system geared toward serving the user and is meant to make your live easier. It supports 'locating' files the way you think about them."
