Why I Don't Use DataSets in My ASP.NET Applications

This was a revealing article for me. I realized that we usually get stuck into what we know, applying same method again and again because we feel comfortable with it, because we are sure that it will work. We also get lazy in investigating and learning more. Why change if it works? Well, in most of the cases there it is a better way of doing things.
In the below article we have DataReader versus DataSet comparison that is definitely useful if you don’t know it already. Read it and apply. It could use a little testing before we just jump into applying suggestions.
