Answer Posted / vasudha.g.n
DataReader
Datareader is like a forward only recordset. It fetches one
row at a time so very less Network Cost compare to DataSet
(Fetches all the rows at a time). DataReader is readonly so
we cannot do any transaction on them. DataReader will be
the best choice where we need to show the data to the user
which requires no transaction ie reports. Due to DataReader
is forward only we cannot fetch the data randomly. .NET
Dataproviders optimizes the datareaders to handle the huge
amount of data.
DataSet
DataSet is always a bulky object that requires lot of
memory space compare to DataReader. We can say the dataset
as a small database coz it stores the schema and data in
the application memory area. DataSet fetches all data from
the datasource at a time to its memory area. So we can
traverse through the object to get required data like
qureying database.
