The free version of SQL Server 2005 is the “Express” edition. Its a cut down
version of SQL Server 2005 and is ideal as an upgrade from Access, for desktop
use or small multi-user databases. Its not designed for large scale production
use, and comes with a number of limitations. The most notable limitations are:
