Introduction to ADO.NET

ADO.NET is the .NET platform's new database technology, and it builds on ADO (Active Data Objects). ADO.NET defines DataSet and DataTable objects that are optimized for moving disconnected sets of data across intranets and Internets, including through firewalls. At the same time, ADO.NET includes the traditional Connection and Command objects, as well as an object called a DataReader that resembles a forward-only, read-only ADO recordset. Together these objects provide the very best performance and throughput for retrieving data from a database.
