Whats FoxPro and Interdev for?

Exactly what the title says, whats Visual FoxPro for and Visual InterDev for?

FoxPro is a database product not unlike Access (I don't use it, but I've heard that it's like Access on steroids). It has its own programming language, based on dBase (it is a so-called "x-Base" database). You don't have to use its language though, VB can be used as a front-end for it.

Interdev stands for "Internet Development". You can use its IDE to build web projects, combining the web technologies like HTML, ASP, VBScript, etc.

Hope this gives you the idea.
