Berkeley DB

Database system and library with C, C++, Perl, Java, Tcl and other language bindings, that can be used to store arbitrary key/data pairs (it can be configured to allow multiple pairs share the same key).

Despite having so simple architecture it supports many very advanced features like transactions?, ACID?, multiple clients and optionally it can even work in client/server mode. Berkeley DB is used as underlying storage system by MySQL and many other database programs.

Berkeley is developed by Sleepycat?. It is available with source code under own Free software licence. Developers who want to use it with non-free? programs must acquire licence from Sleepycat?.

It is backward-source-compatible with some older popular database libraries - dbm?, ndbm? and hsearch?.
