Firebird is an open source SQL relational database management system that runs on Linux, Microsoft Windows, Mac OS X and a variety of Unix. The database forked from Borland's open source edition of InterBase in 2000, but since Firebird 1.5 the code has been largely rewritten.〔(【引用サイトリンク】title=Firebird 1.5.5 Release Notes ) Firebird 1.5.5 General Notes for rewriting it from C to C++ language〕 ==History== Within a week of the InterBase 6.0 source being released by Borland on 25 July 2000,〔(【引用サイトリンク】title=Borland.com: Inprise/Borland Introduces Interbase 6.0 Now Free and Open Source on Linux )〕 the Firebird project was created on SourceForge.〔(【引用サイトリンク】title=Firebird History )〕 Firebird 1.0 was released for Linux, Microsoft Windows and Mac OS X on 11 March 2002,〔(【引用サイトリンク】title=IBPhoenix Community News Archive )〕 with ports to Solaris, FreeBSD 4, HP-UX following over the next two months.〔(【引用サイトリンク】title=IBPhoenix Community News Archive )〕 Work on porting the codebase from C to C++ began in 2000. On 23 February 2004, Firebird 1.5 was released, which was the first stable release of the new codebase. Version 1.5 featured an improved query optimizer, SQL-92 conditional expressions, SQL:1999 savepoints and support for explicit locking. Firebird 2.0 was released on 12 November 2006,〔(【引用サイトリンク】title=Firebird 2.0 Final Release Launches in Prague )〕 adding support for 64-bit architectures, tables nested in FROM clauses, and programmable lock timeouts in blocking transactions. The previous stable release was version 2.1.6, which added new features including procedural triggers, recursive queries, and support for SQL:2003 MERGE statements. Firebird 2.5.5 is the current stable version. New features included improved multithreading, regular expression syntax and the ability to query remote databases. Through the Google Summer of Code 2013 work has begun on integrating Firebird as an replacement for HSQLDB in LibreOffice. The planned 3.0 release is expected to support stored procedures in languages such as Java and C++, and SQL window functions that restrict query results. A first Beta version was released in November 2014.〔(【引用サイトリンク】title=Firebird Roadmap )〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Firebird (database server)」の詳細全文を読む スポンサード リンク
