In the News Management module, in the Data Tier there's these two methods:
NewsManager.Business.News.GetDetails(intNewsID)
and
NewsManager.Business.News.GetDetailsRow(intNewsID)

They both return a news item, but the first method returns it as a NewsDetails class, and the 2nd returns a DataRow.

What is the purpose of having both methods? Only one is used in the code, I forget which one.

They probably changed their mind on how it should work. There's a number of things like this - you can see that the design was evolving even at the last minute.

My preference is to use a class over a row. You want to avoid breaking anything if you decide to add a new column later. By using a custom class you can isolate changes better.
