New SQL Database Engine in C#
Sometimes it happens that genious projects get lost by the amount of C# projects published worldwide. Take a minute and check out this project:
http://sourceforge.net/projects/hypernetdb/
It's a high-performance SQL Database Engine with Index optimization written in C#.
For small to medium .Net projects there isn't anything faster than this.
As the project already offers production quality, some more input & new ideas are always welcome !
