The page you linked to is a custom ASP.NET application, not a DNN app and thus that isn't a module.  It wouldn't be *too* difficult to build something like that custom, or you could probably accomplish a similar app through XMod or ListX (I don't have experience with either, but from what I see they are both pretty in depth).  You might even be able to put something together with the UDT (User Defined Table) module. 

Point taken, I know I've been pushing it a bit. I was kind of surprised at how often Enterprise forms wasn't mentioned when it was an obvious candidate, and thought it should be more in the general conciousness of the community. I know there are other modules that can accomplish some similar tasks and respect them as well.

If anything, however, I've not done EF justice ...
