The DataSet contains the copy of the data we requested through the SQL statement. We can use Dataset in combination with OleDbDataAdapter class . The OleDbDataAdapter object allows us to populate Data Tables in a DataSet. We can use Fill method in the OleDbDataAdapter for populating data in a Dataset.
