The DBFM module is an off-shoot of WebFM, designed to store files in a database as opposed to the filesystem.
This change was made to enable mutli-site replication of filesystem data.
DBFM is, in much the same way as WebFM, the file manager is based on a heirarchical directory structure unlike the traditional flat filesystem used to date. DBFM uses AJAX to allow administrators to arrange files in the database in the same way they do with file managers on their personal systems.
