Free Valentina Community Server Database

Paradigma Software is now shipping Valentina Community Server, a free,
unlimited connection database server based around Valentina 3
technology. This technology uses special methods to reduce the number
and size of tables necessary to build a comparable database with
Oracle, SQL Server or mySQL. Valentina has also been benchmarked by
users as x5 to x10 (and beyond) faster with complex queries than
mySQL. You can work with Valentina Community Server using PHP 4 or PHP
5, with Ruby on Rails support on its way.
