Dataset:1)It is a disconnceted architecture why because
once you fill data in dataset,it'll keep data in it even DB
conncetion was closed.and also no need write code for open
& close database connection.
2)It contain collection of datatables.It can be Add,Edit
and modify at runtime.This property is called Read and
write.
DataReader:
1)It is a Connceted architecture why because we have open
connection to get data from DB.
2)It is Forwarad only.This is only for Reading data from DB.
Diffrence:
==========
DataReader is faster than Dataset,because this is read only.
ADO.net classes
===============
System.data is importent class for ADO.Net.It have
collection of class like Dataset,DataReader.etc...
System.Data.SqlClient;
This is for used making SQL connetion,Command.etc..
Architecture

retive data from DB and then fill dataset to client.and
also It can do Add,Edit and modify operation on DB.

1-data set like a container.it's follow the disconnected
architecture while data reader follow connected architecture.
2-data reader provide forward only and read only access to
data while data set object can hold more than one table from
the same data source.
