to satisfy your curiosity: btrieve is a (comercial) record manager server, that is facilitating access to isam organized data through software interrupts.

further development of btrieve made an sql server, and the meta information about the sql tables and indexes is being kept in a small collection of btrieve tables named file.ddf, field.ddf, index.ddf, fieldext.ddf and comment.ddf. this is where ddf comes from.

btrieve has been widely used for efficient (yet low level isam) applications and application generators, and is now been used also as the backend of the pervasive sql server.

see http://www.pervasive.com for more details.

best regards,
alex
