What are the major difference between classic ADO and ADO.NET?

 Following are some major differences between classic ADO and ADO.NET:

 1. In ADO, we have a Recordset and in ADO.NET we have a             DataSet.

 2. In Recordset, we can only have one table. If we want to                accommodate more than one table,we need to do inner join          and fill the Recordset. A DataSet can have multiple tables.

 3. All data is persisted in XML as compared to classic ADO           where data is persisted in binary   format.
