Dataset - I need to get up to speed fast

Tech-Archive recommends: Speed Up your PC by fixing your registry

I need to get up to speed on the new dataset object fast. Can someone
recommend a primer or other highly condensed tutorial that will give me an
intense injection of practical knowledge on how datasets work?

In particular, I know that a dataset can contain multiple tables but can a
dataset encapsulate hierarchical data arrangements? The particular
application that my company wants me to investigate is if it is practical to
use a dataset instead of an Xml file stream as a data transfer object for a
very complicated project document of variable data contents and shape.
