Serious applications - check these out

[Alex Adams]

I suggest you check into Omnis which is a 25+ years mature cross 
platform client/server application development environment that has 
direct connections to most database back ends.  I've been using this 
product since 1989 to great effect.  They also have a powerful web 
solution.  This tool is used by some of the world's largest 
corporations and also by lone developers for very sophisticated, 
multi-enterprise solutions.

Also check out Apple's WebObjects.  New to me, but it looks really good.
