Wt makes connecting to a back-end database a breeze. There's a whole pile of objects that makes serializing a c++ class to the back-end database easy, plus there are a whole bunch of views for quickly displaying and editing that data. This is one (of the many) place(s) where Wt shines in its phenominal cosmic power.

Wt has a page for their database-objects module which is a good starting point: https://www.webtoolkit.eu/wt/doc/tutorial/dbo.html

Wtx is designed to enhance the already powerful Dbo/Widget (also known as MVC) library to simplify some of the redundant (see; boring) tasks when it comes to stitching Wt dbo objects to browser GUI objects.

I'll swing back around here and get some more notes on the subject.
