ADO.Net uses
1) Oledb
2) ODBC
3) JET Providers

Answer / vivek

Before ado.net 2.0 they give only interfaces to implemetn
them then every provider started implementing on their own
way so problem araised with these implementation.
From ado.net2.0 it gives abstract classes like DbConnetion
to providers.Then the providers create classes to implement
those abstract classes.
Ex:SqlConnection,OracleConnection.
with thses abstract classes we can connect to any backend.
