Firebird database server

Firebird (database server)

Firebird (sometimes erroneously called FirebirdSQL) is a relational database management system offering many ANSI features. It runs on Linux, Windows, and a variety of Unix platforms. Started as a fork of Borland's open source release of InterBase, the Firebird codebase is maintained by the Firebird Project at SourceForge.

New code modules added to Firebird are licensed under the Initial Developer's Public License (IDPL). The original code released by Inprise (as Borland was then called) is licensed under the InterBase Public License 1.0 Both licenses are modified versions of the Mozilla Public License 1.1.


Firebird 1.0 was essentially a bug-fixed version of the InterBase 6.0 open source edition with some minor new features. Development on the Firebird 2 codebase began with the porting of the Firebird 1.0 C code to C++, together with a major code-cleaning undertaking. Firebird 1.5 was the first release of the Firebird 2 codebase and as such a significant milestone for the developers and the whole project.

  • Firebird 2.0 was released in 2006. The latest stable version is 2.0.4 which was released in April 2008.
  • Firebird 2.1 was released on 18 April 2008.
  • Firebird 2.5 is currently in development; an alpha version is expected in the first quarter of 2008, the final by last Quarter of 2008.
  • Firebird 3.0 will merge code from several codebases, including Firebird 2.1, Vulcan, and Fyracle; an alpha version is scheduled for release in Q4 2008.

Around the 20th birthday of the InterBase/Firebird product line, original creator Jim Starkey recollected:

"September 4, 2004 is the 20th anniversary of what is now Firebird. I quit my job at DEC in August, took a three day end-of-summer holiday, and began work on September 4, 1984 in my new career as a software entrepreneur. As best as I can reconstruct, the first two files were cpre.c and cpre.h (C preprocessor), later changed to gpre.c and gpre.h The files were created on a loaner DEC Pro/350, a PDP-11 personal computer that went exactly nowhere, running XENIX. Gpre was my first C program, XENIX was my first experience with Unix, and the Pro/350 was my very last (but not lamented) experience with PDP-11s."

Mozilla Firefox name clash

In April 2003, the Mozilla Foundation decided to rename their web browser from Phoenix to Firebird after a trademark dispute with Phoenix Technologies. This decision caused concern within the Firebird database project due to the assumption that users would be confused by a database and a web browser both using the name Firebird. The dispute continued until the Mozilla developers issued a statement making clear that their software package was called "Mozilla Firebird", not "Firebird". The statement also said that the Mozilla Firebird name was a project codename. On February 9, 2004, Mozilla renamed its browser Mozilla Firefox, thus ending the confusion
