I think ADO.NET is C#


ADO.NET is an evolution of the ADO data access model that directly addresses user requirements for developing scalable applications. It was designed specifically for the web with scalability, statelessness, and XML in mind.

ADO.NET uses some ADO objects, such as the Connection and Command objects, and also introduces new objects. Key new ADO.NET objects include the DataSet, DataReader, and DataAdapter.

Just to flesh that out some....

ADO (ActiveX Data Objects) is Microsoft's layer on top of OLEDB (successor to ODBC) to allow applications to talk to databases in a (somewhat) provider agnostic way. ADO is used in classic ASP, and is the source of the common ADODB.Connection, ADODB.Recordset, ADODB.Command, etc. objects that are used to interact with databases.

ADO.NET is basically the successor to ADO that runs on the .NET Framework. It's used in ASP.NET, C#, VB.NET, etc. to talk to databases. It can use "native" drivers written by application vendors, or the older OLEDB or ODBC drivers. It contains objects such as Data.OleDbCommand, OleDbConnection, DataReader, etc. As you can see, it shares some programming model similarities with ADO - but adds a bunch of new features as well.

Probably the main change in the model is that ADO.NET is designed around a disconnected model (grab the data, disconnect, work with the data, connect, and send updates) whereas ADO was designed with a connected model (open cursor on server, get first row of data, update, get second row of data, update, etc.).
