    Re: What is difference between a DataTable and a DataReader

    DataReader
    1. Its an connection oriented, whenever you want fetch the data from database that you need the connection. after fetch the data connection is diconnected. 
    2. Its an Read only format, you cann't update records.


    DataTable
    A DataTable object represents a single table in the database. It has a name rows and columns.
    There is not much difference between dataset and datatable, dataset is just the collection of datatables.
