InterBase is an open source relational database that runs on Linux, Windows, and a variety of Unix platforms. It is the same commercial database that Motorola, Nokia, Boeing, and the Boston Stock Exchange have used for many years. InterBase offers excellent concurrency, high performance, and powerful language support for stored procedures and triggers. InterBase as an open source database was meant to be available without license fees. However with the recent announcements made by Borland, if you don't want to build your own version from source and you want certified binary versions of InterBase from Borland, you are going to have to pay for it. So whats the alternative? The answer is Firebird - the true open source version of InterBase available for download free of charge and freely distributable.
要发布的话就要购买授权
但由於反應良好, Borland最後改變初衷, 所以最新的interbase 6.5不是全免費.期間, Borland也曾經公開interbase 6.0的源內碼, 從而以GPL發行的'firebird'
(http://www.ibphoenix.com/)則是完全免費的. 最新版本是 (1.0 rc2)
無論interbase6.5或firebird1.0功能完全相同.再者 borland的interbase元件, interbase express或bde都未可發揮interbase應有功能.
建議用 ibo (http://www.ibobjects.com)做ib數據庫開發.
