Think of the dataview as a window into a portion of the data. If you are a
looking at a picture of data you can look at it in certain ways and filter
it to bring out portions of the data of interest to you, but you can't touch
the data. Hope this picture helps you understand what is going on. For a
comprehensive book on the subject as well as other technologies related to
the data layer, see David Sceppa's book, programming Ado.Net.
