Difference between ADO.net Dataset , ADO Record Set & ADO Data Reader?..

Answer / irfanpathan

Dataset is used to get the data from database by creating
objects..After getting data we should store that data.we
use SQLDATAADAPTER for storing data..after storing we will
give connection with SQLCONNECTION class.and then we bind
the data using DATABIND..This total process is appliued
with DATASET.
where as DATAREADER is also for getting data through
database.But it is faster in access.we wont use DATAREADER
because of performance problem..
i too dont know record set..

Difference between ADO.net Dataset , ADO Record Set & ADO Data Reader?..

Answer / lovenier

We use DataSet to retrieve data from database in disconnected mode, but in the data RecordSet it retrieve data in connected mode..
DataSet is designed to work without any continuing connection to the orignal database, but RecordSet is Required a connected environment.
Data in DataSet is bulk loaded, rather than being loaded on demand.
DataSet have no concept of Cursor and current pointer, you can use for each loops to move through data.
