  *: SqliteVersusDbstar - A comparision of SQLite and the db.* database engine
      recently open-sourced by ITTIA.
  
! *: What about EmbeddedMySQL?: ({link: http://dev.mysql.com/doc/mysql/en/libmysqld_overview.html description})  I don't know enough to do a comparison myself, but it seems to have a lot of overlap.
  
  A big turn off for EmbeddedMySQL is their license - here's an extract:
! _:"The MySQL source code is covered by the GNU GPL license (see section G GNU General Public License). One result of this is that any program which includes, by linking with libmysqld, the MySQL source code must be released as free software (under a license compatible with the GPL)." (added by {link:http://www.smartpethealth.com DV})
  
! Another turn off is its size: when i link SQLite into my app the difference is barely noticed not so with EmbeddedMySQL. 
  
  *: What about SimpleSQL?: ({link: http://www.simplesql.org/ for description})

+ *: Sqlite Versus {link: http://firebird.sourceforge.net/ Firebird}  -   
+ Firebird is open source, cross platform, embeddable, has wrappers for many 
+ language. Firebird is a full featured database and has a footprint of 2-3 
+ MByte. A good choice when SQLite is too lite. Firebird can be used free of 
+ charge even for closed source projects.
