Cetin,

No, there's no special DataAccess class. I just use that name to lump all the stuff for accessing data into one layer/tier.

>DataAccessApplicationBlocks does similar to return an SqlReader object.

I haven't even looked at MS's Application Blocks, although I've heard people recommend it.

>PS: Accept me as a newbie to C#,ADO.NET and ASP.NET:)

We all were/are newbies at some point. I have barely used ASP.NET, so I'm certainly no expert at that. =)
