The convenient database engine for a "Distributed" System

[Pierre-Frédéric Caillaud]

	I've not used it personnally, but I heard good things about it :

"Firebird is a relational database offering many ANSI SQL-99 features that  
runs on Linux, Windows, and a variety of Unix platforms. Firebird offers  
excellent concurrency, high performance, and powerful language support for  
stored procedures and triggers. It has been used in production systems,  
under a variety of names since 1981.

Firebird is a commercially independent project of C and C++ programmers,  
technical advisors and supporters developing and enhancing a  
multi-platform relational database management system based on the source  
code released by Inprise Corp (now known as Borland Software Corp) on 25  
July, 2000 under the InterBase Public License v.1.0.

Firebird is completely free of any registration, licensing or deployment  
fees. It may be deployed freely for use with any third-party software,  
whether commercial or not.."

	These seems to be an embedded version so that you can embed the library  
in your app and make everything nice and monolithic.
