What it is: An open-source database engine based on InterBase. Where you can find it: http://www.firebirdsql.org/ Runs on: MicrosoftWindows, LinuxOs, SunSolaris, MacOsx (Darwin), FreeBsd and OpenBsd, HpuxOs and AIX. Supports Transactions in Delphi. -- Maciej Szumocki How it differs from InterBase: Better support, good documentation, and very responsive developer team. ---- What it's not: An open-source browser that's now called MozillaFirefox. ---- I'm somewhat fuzzy on the distinction between a database engine and a database package like MySQL. Is Firebird meant to be embedded into applications like the old Jet and Foxpro DB engines were? ---- You can embed it into your application or run it as a server. I haven't used it for a long time but I remember it was pretty nice. -- TimJarman ---- CategoryDatabase
