| The DBM class provides a wrapper to a Unix-style 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 6, 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. | |||||
