VS.NET and datasets

[sjzjinyi]

I was reading an article on a different site about using the visual studio tools for asp.net development, and the example given created a dataset class by adding a new "Component Class." When I was going through it myself the day before, I had created a dataset class by adding a new "Dataset." It seems they both have the same end result (bound to server controls, filled by a SqlDataAdapter) but I was wondering if anyone would care to venture an explanation of the difference in doing it one way or the other.<BR>
