DBM

The DBM class provides a wrapper to a Unix-style dbm or Database Manager
library.

Dbm databases do not have tables or columns; they are simple key-value data
stores, like a Ruby Hash except not resident in RAM. Keys and values must
be strings.

The exact library used depends on how Ruby was compiled. It could be any of
the following:

* The original ndbm library is released in 4.3BSD. It is based on dbm
library in Unix Version 7 but has different API to support multiple
databases in a process.
* Berkeley DB versions 1 thru 5, also known as BDB and Sleepycat DB, now
owned by Oracle Corporation.
* Berkeley DB 1.x, still found in 4.4BSD derivatives (FreeBSD, OpenBSD,
etc).
* gdbm, the GNU implementation of dbm.
* qdbm, another open source reimplementation of dbm.

All of these dbm implementations have their own Ruby interfaces available,
which provide richer (but varying) APIs.
