The <TT>dbm</TT> library provides access to NDBM databases under Unix.
NDBM databases maintain key/data associations, where both the key and
the data are arbitrary strings. They support fairly large databases
(several gigabytes) and can retrieve a keyed item in one or two file
system accesses. Refer to the Unix manual pages for more information.<BR>
