Command object is only one to execute queries in the
backend.
Ex:
SqlConnection cn=new SqlConnection();
SqlCommand cmd=new SqlCommand("SELECT * FROM EMP",cn);
cmd.ExecuteNonQuery();
cmd.ExecuteReader();
cmd.ExecuteScalar();
Cmd.ExecuteXmlReader();
command object has only these 4 methods to execute queries
in the backend.
