Visual FoxPro has excellent database specific features, functional and capabilities. Many of the advanced database features have been rolled into SQL Server, so that should tell you something. VFP is a highly productive tool as well. You can do an amazing amount of work in a very short amount of time with it.
Visual FoxPro is also well known for speed. You can process an amazing amount of information, thanks to Rushmore technology. In many cases applications written in C (which is fast) couldn't keep up with the highly optimized code VFP produced.
