Firebird is a free and open-source, cross-platform, client-server SQL relational database management system, running on Linux, Unix, and Windows. Please mention your exact Firebird version when asking questions.
Firebird (Wikipedia) is an open-source SQL relational database management system (RDBMS) using the client-server model. It is cross-platform, running on Linux, Unix, and Windows.
It is written in C++, and is ultimately derived from the Borland InterBase 6.0 source code. Firebird is open-source, released under a non-copyleft MPL-like license. It is totally libre and free, for both open-source and commercial applications, but of course you can contribute back with code and donations to the Firebird Foundation.
Firebird and its predecessors have been in use for more than 30 years, which makes it a very mature and stable product.
